Managing Database Systems For A Successful Business

Managing your database system needs crucial planning for greater business productivity. Information and record keeping in any business or organization is  very valuable factor in achieving goals for lifelong success. Handling your business files and other data for further growth and development of your business requires productive tools or aplicativo application programs that will tidy up everything and organize files and information in any way you want them to be to suit your preferences and special needs to make your organization or business become more productive.

Database Types and Characteristics

Database management systems in every company or organization are usually identified as either desktop database systems or server databases. These two types of systems are used according to the organization\'s preferences and the volume of work or information it handles. If you are working alone in running your small business, you may opt for  desktop database system in dealing with all the information and records that your small business hold for your clients and for the entire business itself.

Bigger organizations or companies usually opt for larger databases system that will meet all their huge demands of information processing systems and bulk work that is generally catered by the server databases. Server databases are obviously more powerful than desktop databases. They are also more expensive than the desktop databases.

Choosing Your Own Database Management System

Your small business may eventually grow into  bigger one or may even develop into  huge company or corporation in the future. However, these foreseen growth and development will not just happen in  mouse click or  wink of an eye. This process needs hard work and proper management to flourish each day.

If you will have to examine your business development standards, you will actually realize that you have progressed from  one-man entrepreneur that slowly takes about 3-5 stafe or employees after  year or two then expands to about 20 people or more in your workplace. Of course, you will not just calculate your employee fees here and other overhead expenses in deciding for your ideal database management system. Obviously, you could not deny the fact that your business is expanding so you need  more formal workplace or office space or even  small building that will meet your needs as  team or  expositor-alone business body.

Considering these facts and changes, you now have to think of an ideal database system to manage information within your business. The good thing here is you still have the choice to use desktop database systems if you are thinking about your budget. However, since your business is growing and your human resources are noticeably increasing, it is even more recommended that you switch to server databases. This involves more money to set up such  system yet more rewarding when you become stable in dealing with it for greater productivity.

Evaluating Database Systems

Once you know what you actually need with your business information systems, your final step is to evaluate various options for success. Microsoft Access is  very popular desktop database system used by small businesses. This database application is very much affordable and simple in functionalities. Other desktop database applications that desaparece users promote are FileMaker Pro, Lotus, Paradox and FoxPro.

For server databases, the popular options are IBM DB-2, Microsoft SQL server and Oracle. Server databases maybe costly yet offer the great advantage of providing detailed configuração and solution for  systematic collaboration and enhanced productivity.

It does not matter how big or small your business is by now. What actually matters is how well you manage your business through  well-planned database system and configuração for endless success in each coming year. Do your research very well and consider your own company\'s needs to get your ideal database management solution for further success.

Best Database Management Software

Database managers have  lot of responsibilities. Econômico, customer, and medical data are entrusted to them, and they have to keep these databases functional, accurate, and private. Additionally, they have to keep up with the latest aplicativo, testing to make sure it\'s functional. They have to be ready for disaster recovery, know how to configure hardware, maintain repair and installation records, and troubleshoot database problems.

Whether you work in manufacturing, government, or health care, you have  lot of responsibilities if you\'re in charge of maintaining databases. And you need the best programa available for managing your database files.

Having the right advanced data management solution is  necessity for database managers and database users. You need the features that are found in top-end utilitário. Data structure modification, data editing, data conversion, and convenient search / replace capabilities are all necessities for database managers.

Another task that often falls to DB managers is índice rebuilds and instant re-indexing in open database files. You also need to be able to open, modify, and view the índice files themselves. Knowing the structure of your database files can be very valuable to database managers, and utilitário like DBF File Manager gives programmers and managers these tools.

Ideally,  database manager should be able to conexão with multiple documents and to configure the way in which they conexão with the documents to exactly suit their needs. An intuitive user conexão, like that of DBF Viewer, is necessary so that you can começo using your database management utilitário right away rather than having to undergo extensive training first.

Also, the ideal database management programa should let you work with equal ease whether your DBF format files were created using dBase, FoxPro, Visual Foxpro, or Clipper. In the course of  workday, you may have to add fields, rename them, or delete fields in your files, and with the proper aplicativo, like DBF Editor, you can easily modify your table structure while interacting with an intuitive conexão that makes things easy whether you\'re new to database management, or whether you\'ve been doing it for decades.

Should you need to open índice files (which have extensions.cdx,.mdx,.ntx, and.ndx) after opening the associated dbf file, then you need programa that gives you that capability. These files contain the pointers to records in the database file and sometimes you need to access them using your database program\'s Índice Manager dialog box.

For increased file safety during operations, you need database management programa that allows you to filter records so that you only modify data you need to. Temporary filter functions can be very helpful for keeping your data safe while you\'re working disponível database files.

Database Technology for Real-Time Analysis and Control

Large-scale manufacturing, sewage treatment and power generation facilities are required to leverage increased process visibility which provides better and faster decisions, increased productivity and reduced costs for  sustainable competitive advantage. The key factors and criteria that organizations consider important towards managing, measuring and controlling production processes and costs can be logged into  database for analysis. Process historian database technology, vast protocol connectivity, and intelligent analysis application are all important to complex industrial decision making. Most large systems have  need to store massive amounts of process and commercial data. Different databases often need to work together. Learning differences between databases helps in selecting the best database for your situation.

Limited computer storage capacity became  bottleneck in the IT system. The information revolution has led to far more data now than in the past. Large database systems are generating  flood of new data all the time. With the growth of computer storage capacity, there is  tend to permanently save all sorts of data. More information can be acquired and more information can be stored. Early in the information revolution, security trading systems often only stored recent transaction details. They discarded old information and wrote over the allotted memory space. Now most enterprises tend to save everything that can be saved like every transaction, every phone call, each click conectado  internet sítio da Internet and each switch in communications. Due to this trend, massive amounts of computer storage is getting used. In enterprise-level applications, the cost of saving massive data is often shocking.

Relational databases are commonly used in commercial applications like customer relationship management systems. Commercial applications usually require many fields to be stored like: customer name, company name, address, phone number, and email address. Industrial applications are usually simpler and require fields like  tag name,  measurement value and  time stamp to be stored. Production data is relatively much simpler, yet the point count is usually very large. Real-time and historical data processing is greater than the processing ability of  relational database.  great advantage of the process historian database is simple massive production data and historical data generation.

database comparison study was done by Wellintech, Inc. disponível an environmental protection management information system. They converted the system\'s data into  process historian database from an Oracle based relational database. The database took up 90 percent of the systems hard disk. The system had been operational for three years. The database held  great amount of data and was based conectado  GIS system which stored sistema de navegação por satélite information, maps, locations, time stamps, spacial map information, and locations. The database also held  lot of information conectado the management of the environmental monitoring system. The database was substituted with process historian database and through compression the process historian database cut down the storage space by 25 percent. The space the database occupied was reduced and the querying was much faster with the process historian database.

Process Historian Databases compresses data through  multiple compression algorithm. The changes of industrial production process field data often has waveform laws. Only  small portion tags or variables change in value frequently. The values of the other tags change ery slowly, and users can allow accuracy of data loss within  certain range. Data compression in process real-time/historical databases is  very important technology since it can save massive amounts of space and can aid in query speed.

The CHANGE (0) Compression Algorithm is available for any type of variable compression. It only detects the time-out of compression and verifes the same value detection. It stores the value when  variable has changed. It does not store  variale if nothing has changed. For any kind of compression algorithm, the first step is to check the time and the quality stamp.

The principle of dead banding compression algorithm is very simple. It stores the data when the change in value change reaches  certain threshold. For many variables that change slowly in the novo production process, it can dramatically reduce the amount of data stored.

The swinging door compression algorithm was first proposed by OSI Soft PI. The algorithm s relatively simple and PI opened the entire algorithm to the public. Now, almost all process historian databases have adopted this compression algorithm, and have added new technologies in with it to make it more optimal. The principle of the swinging door algorithm judges whether  data point needs to be saved. It draws  straight line between data from  previous saved point P to the next data point N. It checks the absolute bias of those data points (including ) between two points (P, N) and the data points disponível that line corresponding to the time stamp. If there is bias of the point that exceeds the compression bias, that point  should be saved.

These compression technologies can help you to save storage space, enhance data querying speed.  vast amount of data is being collected in industrial databases from measurement instruments and control hardware. Many industrial communication protocols are being used in many different industries. BACnet and LonWorks are commonly used in HVAC systems, 102 Protocol in power plants, and Modbus in process control.  large amount of connectivity of data collection is very important in intelligent information systems.

Intelligent analysis for efficiency in all industries requires collection of data from hardware, storage of data to  database, and conversion of the data into usable information for decision-making. Data can be converted into information through process historian database analysis tools which can help you compute things like how many tons of water gets treated in  sewage treatment plant in one week. The historical data analysis tool can predict the future events, or estimate uncertain past events.

Relational databases are great for commercial or smaller systems. Process istorian databases are great for industrial applications where measurement data does not dramatically change over time or requires fast querying speed disponível vast amounts of data.

Web Database Development Services

With the web and World Wide  revolution, almost all companies are now setting up websites to be able to serve their customers appropriately. Most of these websites are just simple-informational websites. The simple websites do not require databases as they do not require holding of data conectado. When it comes to big organizations, their websites are  bit complex. Their websites require databases for holding data. The data to be held belong to either the organization\'s employees or customers.

If an organization deals with  lot of data, it needs to have  database for their rede. This database allows for storage and processing of the data received from the visitors to the conjunto de páginas da Internet and data to be supplied to visitors to the conjunto de páginas da Internet. For instance, if you are  banking institution, you will have cases of customers trying to check their accounts statuses from the sítio. You will also have employees accessing the database from the rede. If you want such  complex sítio you need to contract  database development services. These are services from individuals or organizations that will take care of your entire database  matter how complex it may be.

The rede database developers offer services like database refactoring and optimization. Apart from creating the databases for your rede, the developers also deal with issues of poor performance of the database and lack of scalability and interoperability. The developers help in database testing, improvements in implementation and database refactoring.  good developer will create  database for your rede that handles both unstructured and structured data.

good database for your rede transforms your business requirements into  physical database desenho industrial. The developers combine their rede desenho industrial skills and database configuração skills.  internet database is simply an ordinary database which is accessible from the conjunto de páginas da Internet. One can retrieve or modernização information in the database from the organization\'s conjunto de páginas da Internet. Internet database development may seem expensive to an organization but its not. The database saves the organization  lot of costs in terms of clerical costs. By customer accessing information from the conjunto de páginas da Internet, they do not visit the organization acessível regular basis for information. When few customers visit the business premises for information, the organization can lay off adicione of the clerical grupo. Also, with  database for the rede, the organization does not need to open branches in different parts of the world/country. Customers can envio or download information from the database from anywhere in the world/country.

The database development is based acessível  number of key principles. These principles are security, performance and data quality management. The principle of security ensures that the organization data is safe from unauthorized access or alterations, thus securing the stored data. Security is enabled through  number of ways e também.g. data encryption, database audit, passwords etc. To ensure performance of the database, special techniques of data caching, clustering and load balancing are employed. Quality of data is also an important factor to consider when designing the internet database. To ensure quality of data, accuracy and consistency of data should be ensured.

Database in SQL Server

Ever wanted to make  read-only point-in-time copy of  database, and wondered which technique to use? Microsoft SQL Server 2005 provides  plethora of ways to do this, including database backup/restore, database detach/re-attach, log-shipping, replication, mirroring, and so forth. However, one method available in the Enterprise edition, the Database Snapshot, is new to SQL Server 2005, and is worth taking  closer look.

Why are Database Snapshots Useful?   There are many applications where  point-in-time snapshot is useful. Microsoft suggest the following use cases:  

Reporting up to  specific time period, ignoring later data Reporting against mirror or standby databases that are otherwise unavailable Insuring against user or administrator error, providing  quick way to revert to an older version of the database Managing test databases, particularly during rapid feature and schema development Of course, these needs could be served by  database backup or attached copy of  database, but the key benefit of choosing  snapshot over one of the other methods is simple: creating  database snapshot is fast. Creating and Using Database Snapshots   Creating database snapshots is easy - it\'s  CREATE DATABASE statement, specifying only the logical and physical filenames. Remember it\'s  read-only snapshot, so we don\'t need to add autogrowth or transaction log settings. Here\'s the code:

CREATE DATABASE AdventureWorks_Snapshot_Monday ON

( NAME=AdventureWorks_Data,

FILENAME=\'C:SnapshotsAD2K_Monday.ss\'

)

AS SNAPSHOT OF AdventureWorks

Snapshot creation is not supported by the Object Explorer área de interação in Management Studio; you must use  CREATE DATABASE statement as above, with the AS SNAPSHOT OF clause indicating the source database. Also, note that only the Enterprise edition of SQL Server 2005 supports database snapshots.

The snapshot contains  version of the data as it existed at its creation, having rolled back uncommitted transactions. This means that otherwise unavailable databases, such as mirrors and standby servers, can be used to create snapshots.

Having created  snapshot, you can now use it as you would any other read-only database; all objects are exposed in exactly the same way, via Object Explorer, scripts, or reporting tools.

Reverting  database to the version stored in the snapshot is similarly easy:

RESTORE DATABASE AdventureWorks FROM DATABASE_SNAPSHOT=\'AdventureWorks_Snapshot_Monday\'

This returns the database to the state it was in when the snapshot was created, minus any uncommitted transactions - remember that  snapshot is transactionally consistent at its creation. Note that restoring from  snapshot renders all other snapshots unusable - they should be deleted and re-created if required.

How do Database Snapshots work?   Database Snapshot looks like an ordinary read-only database, from the user\'s point of view; it can be accessed with  USE statement, and can be browsed from within Management Studio. However, it initially occupies almost  disk space, and so can be created almost instantly. This magic is achieved via an NTFS feature, sparse files.  sparse file is  file that may appear to be large, but in fact only occupies  portion of the physical space allocated to it.

Now, because  database snapshot presents  read-only view of your source database, it need not store  copy of every page. Instead, SQL Server performs  copy-acessível-write operation; in the source database, the first time  data page changes after the creation of  snapshot,  copy of the original page is placed in the sparse file. The snapshot serves data from the snapshot copies where source data has changed, and the original source pages when they are unchanged.

Best Practices   Sometimes you will choose  copy of  backup over  snapshot, sometimes it\'ll be  detached copy of the data file. However, for many situations your best bet is  database snapshot, so it\'s worth keeping adicione points in mind. In pessoal:  

The file size will look considerably larger than the space it consumes disponível disk, and should be clearly marked as  snapshot for this reason. Use explicit naming conventions to make it clear to administrators. Snapshots are at their best when young and fresh, and don\'t take up too much space. If you need to keep  snapshot for any length of time, consider using another method to create your read-only copies. As snapshots persist until deleted, you will need to explicitly rotate snapshots, either manually or with  script. Performing índice operations such as defragmentation or índice rebuilding will modify so many pages that the snapshot will likely contain  complete copy of the source data for that índice. The more snapshots there are, the more copies will exist. If the disk containing  snapshot fills up, and  page write fails, the snapshot will become useless, as it will not contain all necessary pages. Make sure the disk can\'t fill up! Database snapshots are  worthwhile addition to the arsenal of any SQL Server DBA, and fit well with other techniques, particularly when you may need to quickly revert  database, or if you need to maintain rolling snapshots. Remember the key advantages: high speed and low physical size. But also remember that these advantages diminish as the snapshot ages and grows, and if the number of snapshots increases. Above all, database snapshots are fast and easy to use; it won\'t cost you anything to try them out, and you will probably find them very useful indeed. If all you need to do with  point-in-time copy is select from it, or possibly revert to it, then  database snapshot is likely the best choice available.

Tips For Choosing and Using MySQL Database in a Web Hosting

Most widely pronounced \"my ess cue el\", \"my sequel\". MySQL is  leading open source relational database management system. It is largely SQL-compliant and runs acessível  wide variety of operating systems. MySQL is part of the popular LAMP server configuration, Linux Apache MySQL PHP/Perl/Python. Today, it is undoubtedly the most popular and widely used database management system for building database driven websites. It provides  solid backend foundation for millions of websites globally.

Any form of data you may have that requires storage, whether it\'s  customer database or accounts records, is stored disponível  database. You will need  database management system to create, add, manipulate, and process data in your databases, and undoubtedly, MySQL is one of the best and most comprehensive DBMS (Database Management Systems) packages disponível the market today. It can also be used as  relational database management system, which means it can store data in various tables that can communicate with one another rather than all in one large \'flat file\" of data.

MySQL can be run as  server disponível your sítio pc or in  remote dedicated server. The mode of access for MySQL databases and MySQL functionalities is all dependent disponível the rede hosting company used. This could be via  hostname or IP address of the MySQL database server. For complete and seamless management of your databases, most internet hosting companies provide  client management platform for your to carregamento and configure your MySQL databases. The most popular and widely used MySQL client today is \"phpmyadmin\". Using phpmyadmin allows you to input your various commands, most likely using scripts, to interact with your databases. These commands can be written disponível PHP programming scripts or within the database management client aplicativo.

When choosing  MySQL  hosting provider, you\'ll want to consider desaparece additional factors beyond the standard server uptime, backup/redundancy systems, bandwidth, email, and bandwidth concerns.

Unlimited MySQL Databases: If you are considering the services of  MySQL  hosting provider, you\'re surely planning conectado making databases  significant part of your rede-presence. You therefore need to find  MySQL hosting provider that offers you unlimited MySQL databases, with unlimited storage space. This will give you the freedom to scale up your operations and create more databases without any additional cost(s) acessível your part.  rede host that promotes itself as  MySQL hosting provider must offer its clients with unlimited databases. You must always do your research and compare services and features of  good number of hosting companies before making  final decision.

Database Client Management Conexão: It is  doubt that you\'ll be working with your databases acessível  frequent basis, and therefore, you\'ll want  MySQL hosting provider that\'s designed  user friendly admin área de interação with MySQL user in mind. If you have various development grupo involved in the desenho industrial, building and maintenance of your databases, you\'ll want to have the facility to be able to create multiple user I.D.\'s to allow varying degrees of secure access to databases. Phpmyadmin is good administrative utilitário to have for MySQL databases.  good and reputable internet hosting company should as  default provide this tool as part of its MySQL database hosting service.

CRON support: You\'ve spent  fair amount of time looking for  new  host for your websites, and you are comparing features, prices, and support options trying to find the best match for your needs. One vital thing that should crop up in your mind is something called cron jobs. What is exactly is CRON, and is it something you really need and should form the basis of your decision to go with  pessoal internet host?

CRON is  scheduling daemon available conectado Linux and other UNIX operating system variants.  cron helps you to run specific scripts for regular, routine tasks to be run at periodic intervals.  MySQL hosting provider should allow you to set up and manage crons from your admin control panel. These scripts are also good for Preventive Maintenance routines.

I know this will probably not mean much to you, but don\'t worry too much about it, as I\'ll explain it better. Let\'s assume that you own  conjunto de páginas da Internet, and visitors to your conjunto de páginas da Internet sign up for  periodic service you offer, but getting an email for each person that signs up is getting too daunting and  burden, and adicione are starting to slip through the cracks. Wouldn\'t it be nice if there was  better way to get one notification  day with all the names and emails of those who have subscribed to the service?

CRON was invented as  result of this. Any  developer familiar with the workings of cron jobs could easily write and schedule  script to run once  day and email  list of all subscribers for that day. Executing  script or program at  scheduled time is the very reason cron exists. This takes away the mundane task of getting  notification for each subscriber.

Cron job settings by default are kept in  file called \"crontab.\"  simple editing of this file can allow cron jobs to be executed whenever you want. To the unfamiliar, the crontab file can be pretty confusing and intimidating sometimes. It is exactly for this reason that most  hosting providers only allow access to cron through an easy to use  área de interação. One vital thing to consider is to make sure that you choose  internet host that provides this simple internet conexão for cron.

PHP Information: The most common script for MySQL databases is PHP.  MySQL hosting provider with PHP extensions enabled is likely to be more frustrating than useful to you. By checking into  prospective MySQL hosting provider\'s PHP capabilities, you can ensure compatibility between your scripting language and your database management, thus saving yourself trouble and regrets in future. Poor decision made could ruin your internet presence.

Finally, if MySQL database is the database of choice for all your websites; make sure that you get  host that specializes in MySQL hosting. This is vital for the overall stability and functioning of your internet applications.

Monitor and Audit Database Security

The database of  company is the storehouse of all the vital information and data pertaining to the functioning of the firm and is intended to be absolutely confidential and protected from any attack by  cibernética criminoso. The possibilities of  database being hacked and misused by attackers are high because it is accessible to the user from anywhere. Hence it becomes the foremost duty of an administrator to protect the database by constantly monitoring the functions and look for any loophole that will benefit the attacker.

Database security is done periodically by the administrator of the company\'s sítio for closely monitoring the activities of the users who have access to the database. This is mainly done to prevent any tampering of the database by anyone who has permission to reach the data acessível the database. It is also done to ensure that  person without the proper authorization is allowed to enter into the database. The database security and auditing are done in many methods such as securing the server, monitoring the connections to the database, access control, and enforcing restrictions disponível the access to the database.

Restrictions to database access: When the database of  company is controlled via the web, this measure is at its best use. There will be  list of users that are authorized to access the data disponível the database and when this access is restricted, the data is all the more secured. When this is applied, the user will be able to attempt logging in only three times and if he fails in providing the correct password, his account is disabled and he will not have the privilege of accessing the database again. When somebody is trying to access the database from an unknown destination, such attempt can also be thwarted by this tool.

Access control: Said to be one of the toughest and hardest security audits conectado the database, the security of the data is high when this is applied. The method requires the combination of efforts of both the administrator and the developer for the database. When this method is brought into effect disponível the database, all the systems that have access to the database are checked thoroughly and  list of all the persons who will have the authority to gain access to the database is prepared. This makes the task easier to monitor the activities of all such persons closely and if anything suspicious is found, his access is cancelled, thus ensuring the better security of the database.

Connection to database:  updates that are unauthorized are permitted by the system administrator to be done acessível the database. He needs to thoroughly examine any incremento that has to be made to the database and found to be genuine and safe. There could be others who have the permission to incremento the data disponível the database too. It is the duty of the system administrator to frequently check that this privilege is not misused and vital information is tampered. He must be constantly watching these persons for not crossing the security measures and mishandling the data.

Security of the server: By using this method, the number of persons who will have the authority to access the database can be restricted. This is done keeping in view the probability of anyone accessing the vital data conectado the database and tampering it.  unauthorized person can login to the database. Only the computers which have  legitimate IP address are permitted by the server of the company to access the database. The server of the database, in turn, is programmed in such  way that it will allow only the connections that are made from  pessoal  server. As  result,  outsider will be able to gain access to the database of the company.

Other measures: Firewall configuration will help in protecting the data and ensuring the security of the database. The company should not use the system passwords and other parameters provided by the vendors. All the data that are very confidential are to be protected. The sensitive information needs to be encrypted for public networks. All the security systems and applications are to be updated at regular intervals. Each user is to be provided with  unique ID for accessing the database.

These are desapareces of the measures that need to be meticulously followed for ensuring the safety of the database. Frequent auditing of the safety measures and updating the tools can also be of immense help in protecting the database of  firm.

Database

Database Fundamentals must be prepared to all the computer professionals and users. If you lack in their moderno   meaning of terms, you would always find an uneasiness and discomfort when these   jargons come to you. This article is targeted to  novice and expert both, so   that novice can prepare and an expert can revise things as well. My approach is   to mention all the things concerned with database concepts.

[1] Entity and Entity Relationships :

Entity :

An Entity is place, object or thing for which we can collect information.

Such as Student is an Entity and we can collection information like Name, Phone and Address. Here, Name, Phone and Address are the Attributes of entity \'student\'.

Entity Relationship Diagram :

Also called as E também-R Diagram. E também-R Diagram is the graphical depiction of the entity, its attribute and relationship between entities.

[2] Data and Database :

Data :

Data are the single unit of an information.

Such as if name of an employee is \'John\', then \'John\' is  data. His telephone . is   \'+9109880959786\', then, this is also  data. The value of the attribute of any entity can be said as data.

So, Data are the known facts that can be recorded and have their implicit meaning. e também.g. name, telephone, address etc.

Data is  variado and \'Datum\' is the um form of the data.

Information :

When the set of data are collected together in  meaningful manner, an information is generated.

Such as if we take example of an employee \'John\'. The Name is \'John\' , Telephone . is   \'+9109880959786\' , designation is \'DBA\'. So, if we collectively analyze these, we get information that   \'John\' is an employee with telephone . \'+9109880959786\' and he is designated as   \'DBA\'.

So, When the desapareces set of data are collected together, information get produced.   Although, this information is not for computer, this is just for humans only.

Database :

Database is the collection of related data.

Database is logically coherent collection of data with desapareces inherent meaning.  random assortment of data can not be said as database. Such as  Telephone Diary is also  database, but, if it is randomly stored then, it can not be said as database.   Database can be generated manually or in computerized manner. The Library catalog is also  database.

[3] Database Management System (DBMS) :

Database Management System is the collection of programs and tools that enables users to create and maintain the database.

DBMS is also  general purpose utilitário system that facilitates the process of defining, constructing and manipulating databases for various applications.

Characteristics of Database Management System :

(1) Self Describing

(2) Insulation from Programs and Data Abstraction

(3) Support of Multiple views to Database.

[4] Advantages of DBMS:

1- Controlling Redundancy :

There are provisions in all database models that redundant storage of the data can be avoided.

2- Security Over Unauthorized Access :

This is the feature found in the database that without proper login,  one can modify or store database. The security can not be achieved with the flat file (Sequential) approach.

3- Providing Persistent Storage for Database Objects :

Database can be used as the persistent storage of Program objects, Database and Database structures. This meant that  complex object of programming languages can be stored in the database. This gives more flexibility and compatibility of database over the programming languages.

4- Permitting Inferencing and Actions using Rules :

Inferencing is the method for defining deducing rules for inferencing new information from stored database. Such database are called as Deducible Database. In other words, there must be desapareces methods to provide information by logical implementation disponível the stored database.

6- Allowing Multiple User Conexão :

DBMS has the capability to provide concurrent execution of various parts of the database. In this approach, Deadlock and other anomalies are also handled by the DBMS.

5- Backup and Recovery :

Database Management Systems have proper mechanism to Backup the whole database and recover when any disaster comes to picture. There are methods for Disaster Recovery in all DBMS.

[5] Data Models :

data model is the set of conceptual tools for describing data, their relation, semantics and consistency constraints. There are following data models-

(1) Hierarchical Model

(2) Network Model

(3) Relational Model

(4) Object Relational Model

Describing all of these would be out of context. You should know that with all these, Relational Model is famous one. Newer implementation of DBMS do follow Object Oriented Model. Such as Oracle, Sybase and SQL Server.

[6] Logical and Physical Data Independence :

Data Independence is the quality of DBMS that ensure the capability to change the database in  manner that the change in one level does not affect the other level. Such as change in the physical storage (Internal Level) does not affect the database structure (Conceptual Level).

(1) Logical Data Independence:

Capability to change the Logical structure without changing the external and internal schema of the database.

(2) Physical Data Independence:

Capability to change the Physical schema without any change in the conceptual schema of the database.

[7] Database Languages :

There are following database languages-

[1] DDL (Data Definition Language)

[2] DML (Data Manipulation Language)

[3] DCL (Data Control Language)

[1] DDL (Data Definition Language)

This is the language concerned with the creation of database structure and schema related with this. This language is concerned with the definition of the whole database architecture.   DDL is used to define and manage all the objects in an database. Such as creating Databases, creating security objects that define the whole database.

[2] DML (Data Manipulation Language)

Insertion, Incremento , Delete and Selection are the activities concerned with the database manipulation language.   DML is used to Select, Insert, Incremento, and Delete data in the objects defined using DDL.

[3] DCL ( Database Control Language)

Database control language is concerned with the consistency maintaining, authorizing access and other control over the database.

There are desaparece other languages which must be known. These are -

VDL (View Definition Language) : Providing means to view the conceptual schema of database for external level of three level schema.

SDL (Storage Definition Language) : Providing means to change or modify the internal schema of the database.

[8] Relational Database :

The Relation database model is based upon the conception of implementing the database with the Mathematical Set Theory. In this model, data is collection of tables called Relation in the set theory. The Tabular representation of data contains rows and columns in which rows represent set of attributes of individual entity and the columns represent the attribute of entity.

model is also said as Relational Database Model, if it follows complete set of Rules defined by Dr. E também.F. Codd. There are 12 Rules of Dr. Codd. In all of them, only Oracle is supposed to follow nearly all of them. But, the best in performance is Sybase which is more easier to configure that of Oracle.

SQL :

SQL is actually Structured Query Language. This is pronunciated as \'sequel\', but \'Ess-Que-El\' is also correct.   It was initially named by Dr. E também.F. Codd who named it Structured English Query   Language (S E também Que L ) as Sequel.

SQL is based acessível the Relational Model. Nearly all the database implementation in the world are in Relational Model. Sybase ,SQL Server, Oracle,   DB2 are the famous implementation of Relational Model. But these are also kept in the Category of Object Relational Model.   Microsoft Access is not supposed to be relational model. This actually uses desapareces   flavors of relational database. But, can not be taken into account of pure   Relational database.

ANSI-SQL :

American National Standards Institute handles the standards of SQL. The changes   are made time to time. We have ANSI-SQL-89, ANSI-SQL-92 and other standards.   There are several levels decided. Microsoft SQL Server is given entry level.

Conclusion :

This is all about providing protection for passwords. There are many other   things to research in the same scenario and I would like to share my ideas when   such studies are complete. Overall, my aim was to open your eyes that backups   are not only to secure your data, but due to carelessness this may lead to   leakage of information. In my opinion, disclosure of important information is   more serious matter than loss of information. So, awareness is important and   there is  little effort to apply in securing your backups.

How To Build and Maximize the Power of Your Database

If you have read any of my previous articles, you know that I am  big advocate of database management. The purpose of this article is to dig deeper into the nuts and bolts of how to build, develop, and maximize your database with the goal of increasing your profits.

Many business people do not even have  database, and those that do many times do not consider it anything more than an electronic rolodex designed to keep track of phone numbers and email addresses. I can tell you from personal experience that  database, if properly cultivated, can be so much more, and can in fact be one of the keys to increasing your business.

We will explore the following five key elements of building  successful database in this article:

1. If I don\'t already have  database, how do I get started?

2. What characteristics should I look for in  database program?

3. What information should I put into my database?

4. What tasks should my database accomplish?

5. Database maintenance and daily use.

If I don\'t already have  database, how do I get started?

If you don\'t already have  database, the key is to get started as soon as possible and get in the habit of using your database every time you come into contact with  prospect, business partner, or customer.

Do not get analysis paralysis and over-analyze the situation. It is important to understand that habits take time to develop, and using your database will not be easy at first. Especially in the first month, you will spend  lot of time getting your database up and running. There will be  lot of data entry involved to get your current contacts into your database.

The first step is to gather all of your paper records so that you can enter them into your database. Customer mailing lists, rolodexes, business cards, old files, anything you have that has contact info for people you have come into contact with. You should include past customers, prospects, business contacts, and anyone else you know.

The other thing to consider is what database system to use. It is difficult to começo with one database and then switch to another  couple months later, so do your homework and decide which one will best fit your needs. There are many industry-specific database programs, especially in fields such as real estate, and there are also adicione good general-purpose programs such as ACT! and Outlook. My program of choice is ACT!, and although it is not without it faults, it accomplishes 99% of what I am looking for in  database program.

What characteristics should I look for in  database?

Your database program, disponível  basic level, should keep track of phone numbers, email addresses, physical addresses, and other contact info. It should also be customizable so that you can add fields to keep track of specific data that is important to you or your line of work. For instance, I am in the mortgage industry, so one of the features I like about ACT! is that I have been able to add  couple hundred specific fields to my database such as information about the loan that my clients have, their financeiro information, and other mortgage-related data.

I have also programmed in fields that help me with prospects such as time frame for buying, most important hot points, best time to call, referral source, referral date, and other relevant data for acompanhamento.

There should also be  place where you can take notes under each contact. I use the notes/history tab in ACT! to record key elements of each conversation I have with  prospect, client, or business partner and try to take my notes immediately after the phone call. If I get an email from  contact, I simply copy and paste the entire email into the notes/history tab. You will find that if you take good notes disponível your conversations, it will be easier to build rapport because you can refer back to key points and details about your prospect that will impress upon them that you were paying attention and that they are important to you.  human can remember everything about everybody and every conversation, so take notes!

Another key feature that any database will have is the ability to schedule reminders. After each phone call I have with  person, I schedule the next appointment or phone call so that I don\'t have to remember to do it. Related to this is the ability to schedule an activity series. ACT! for example has  feature where I can program in  series of activities at the click of  button that may be common to multiple contacts. The privado series is already pre- set in the system.

Mail merge capability is yet another key feature that you should look for in your database program. If you are not familiar with mail merge, you should take the time to learn what it is and how it works. Mail merge will allow you to send out  group of emails to multiple people, but customize each email for each contact you send it to, using information from their contact record. For example, you can send out 100 emails, and each one will be customized to say \"Dear \"First Name.\" This is  powerful feature that if used can help build your business with minimal effort disponível your part. Mail merge can also be used to generate customized paper letters.

The final feature that must be part of your database program is the ability to do complex lookups. What I mean by this is that you must have the capability, for example, to look up all contacts in your database who bought something between July and December of 2005, or you may want to look up all of your clients with last names from -M. Basic database programs will only allow you to look up contacts conectado one level. Better database programs, such as ACT! will allow you to look up conectado multiple levels. For example,  good database program will let you look up all of you clients in California, and then further narrow it down within that group to Clients with last names from -M. Not so good database programs will only allow you to look up clients in California, but then you couldn\'t go another level down and narrow the search. You will find that you want this feature as you get deeper into databasing.

What information should I put into my database?

At the very least, your database program should serve as an electronic rolodex. But, with only this minimal information, that\'s all it will be to you. Again, it is important to make sure you are getting  program that is customizable so that you can add the fields you want. In addition to phone number, addresses, and names, here is  brief list of desaparece of the items that I have included in my database:

Referral source, referral date, página da Internet address, best time to contact, preferred form of contact, hot points for sales, ID number, status, time frame, birth date, number of children, hobbies, surveys, and industry specific information that pertains to your business.

You should also have  notes section in which to record notes conectado conversations with your contacts. It is also very useful if your database program keeps  history of emails, phone calls, and appointments that are recorded automatically when you \"clear\" your reminders.

What tasks should my database accomplish?

Your database should allow you to verificação with your prospects, clients, and business partners, in an efficient, methodical way that doesn\'t take  lot of your time. In my opinion, this is the single most important thing that your database can do for you to help you grow your business.

The key is to develop systems that help you stay in front of every person that goes into your database, literally forever. For example, I have categorized my contacts into six general categories for seguimento: prospects, clients, \"in process\", \"delayed leads\", Realtors, and Business contacts. I have developed specific and automatic verificação systems for each category. These systems incorporate different types of contact: email, snail mail, and phone. Once  contact is put into  pessoal category, they are plugged into the acompanhamento campaign for that category forever.

With  follow-up system like this in place, it is not  coincidence that when it comes time to buy, your prospects will think of you. When it comes time to refer, your business partners will refer to you. And when they do, it is important to get into the habit of opening up your database from the first second of the first phone call with each prospect or new contact. Take good notes, ask good questions, and record it all in your database. The more you know about the people you come into contact with, the easier it will be to sell more.

Database maintenance and daily use

The final key to developing an effective database is to make sure you have  maintenance system in place. You must first of all purge your database acessível an ongoing basis of contacts with bad phone numbers, bad emails, etc.

Once you get deep into database management, you will become so reliant disponível your database that it will be the backbone to your business. It is extremely important to back up your database disponível  regular basis and to store the backup disponível an external source. I am to the point where if I were to lose my database, my business would be in serious jeopardy. I back up every 3 days, and store the backup acessível an external hard drive as well as disponível my desktop.

Developing an effective database will not be an easy task and at first you may question my assertions in this article. However, with persistent work, over the course of just  few months, you will see that an effective database will transform your business and take you to new levels.

Database For Marketing

database helps manage information to produce meaningful results. Travel agents are among the most experienced users of databases. All computerized reservations systems rely upon sophisticated databases of flight inventories and reservations. Agents also maintain client databases in traveler profiles. What differentiates these databases from those developed in-house conectado computers is that the airlines, not the agents, control them.

characteristic of databases is that the data is linked into one useful system. For example, an agency may store client information acessível índice cards. By shuffling through these cards, it is possible to identify who went disponível which tour, produce an alphabetized list, or, rearrange the cards in zip code order for  bulk mailing. Similarly,  database provides an automated, or \"computerized,\" method for recording and storing data.

Data in and of itself has  use. It is only when it is processed - selected, sorted, or arranged in desaparece meaningful way - that it has any utility at all. Names, addresses, numbers, and dates are typical of the data you may need to store. Data becomes information only after it is arranged in  manner to answer  question, solve  problem, or take action.

This fundamental concept should guide the development of your database. Unless the data you collect can be used to answer  question, solve  problem, or take an action, it is probably not worth the effort. Automating useless data gets you nowhere-only faster.

Database Development

The development of  database may pose several hurdles: learning how to master new programa, and figuring out how to computerize all of the notes, cards, and lists that now comprise your \"database.\"

Taking disponível all of these hurdles at once may be overwhelming. If you have only limited experience using  computer or  experience in developing  database, you may want to consider employing an outside contractor to assist you. You would desenho the \"specifications\" for the database, including the data to be included, the kinds of information the system should produce, and the activities you want to accomplish, such as mailing lists and monthly reports. An outside contractor can then take your requirements and develop  database.

Although it may be more costly in the calção run, requiring the contractor to train you or someone conectado your stafe conectado the aplicativo will enable you to maintain the database more effectively and develop new databases as the need arises.

If you are experienced acessível computers, or are persistent and patient, most aplicativo packages offer  step-by-step approach to database desenho industrial in tutorials that should enable you to develop your database yourself. Whether you use  contractor or develop the database yourself, selecting the right aplicativo for your present and future needs is an important decision.

Database Aplicativo

There are two main forms of computer programa for databases - (1) record-oriented databases, and (2) relational databases.

In  record-oriented system, one record is created for each traveler in the system. In  relational database,  traveler\'s name would appear conectado several related lists. The distinguishing factor between the record and relational database is the flexibility and added capabilities characteristic of  relational database. The trade-off is that while relational databases are more powerful, they also require more time to master.

Database Desenho industrial

While this article focuses conectado the use of databases for marketing leisure travel, the principles of database organization may be applied to any database. Before beginning the desenho industrial of  database, define the functions the data will be expected to perform. These should be the moderno activities you plan to automate through the database, such as mailing lists and traveler preferences, etc. Time taken to carefully specify the expected uses of the database will be rewarded many times over in the future.

Once the uses for the database have been determined, factor these into the data elements needed to furnish the requisite information. Since the same data is used for many purposes, expect many of the data elements within the categories to overlap. This \"paper and pencil\" work will require several drafts to come up with the right data.

Data elements for the previously defined uses might include:

• Personalized information disponível prospects

Name

Nickname

Spouse\'s Name

• Special interests

Hobbies

Travel Interests

Spouse\'s Interests

• Group Affiliations

Group Memberships

Spouse\'s Memberships

• Unique Preferences

Travel Preference

Lodging Preference

Other Preferences, needs (wheelchair accommodation, dietary restrictions, etc.)

• Promotion Effectiveness

How did prospect hear about trip or tour

• Market segment

Market segment code

• Mailing Lists and Letters

Home Address

Home Phone

Business Address

Business Phone

Database for Marketing

The list above illustrates how data elements are identified. The unique feature of databases is that they may be customized to suit virtually any need. The database that you desenho industrial will have an array of data elements that will fit your specific needs. And need is the key concept. Once the list has been developed, go over the list to determine which data elements are missing and, equally important, which data elements are not needed. Superfluous data extracts  high price in  computerized database - more input, more disk space, more maintenance to keep the data current.

Once the data elements have been identified, configuração the screen espelho for data input. In designing the espelho, the following principles are helpful:

Plain English. While travel abounds with acronyms, such as fone, using plain English means that you will not have to hire  travel agent each time you want to enter data. An easily understood input screen goes  long way to explaining what data needs to be entered.

Load data that changes first. Adicione data needs to be changed more frequently than others. Entering these data eliminates the need to scroll to the bottom of the record to modernização  line. This means data that one usually thinks of first, such as name and address, is put at the end of the record since it is least likely to change.

Utilize error trapping. Many programa packages include error trapping features that monitor if data has been entered correctly. The extra time required in setting up error trapping routines makes input easier and information more consistent.

Employ multiple screens. Most databases allow more than one screen to input information. Multiple screens enable you to include the detail required to make  database more effective than just  mailing list.

Include maintenance data. Maintenance data records when and by whom  record was last updated. This information is helpful in monitoring the timeliness of the data and establishing accountability for the quality.

Putting the Database to Work

As the database is maintained, it will take conectado  life of its own. You will begin to think of new applications for the data that exceed your original definition.

Understanding SQL Web Hosting

SQL is the acronym for Structured Query Language, which is  computer language that is used to manipulate data in  database. SQL works with many different database systems, such as Access, Oracle and MS SQL. SQL is widely used due to it\'s simplicity and applicability to diverse database functions, many of which make up global business systems and commercial computer aplicativo.

Rede Hosting is  service provided by  company that leases server space to companies or individuals that have internet pages they want to display disponível the rede. Internet hosts provide the necessary bandwidth and technology to allow web users to access these internet pages. While anyone can create  rede page, special servers dedicated to rede connectivity and hosting are required to make the internet page active. Therefore, SQL  hosting is  service that allows SQL databases to be hosted disponível the web. SQL  hosting can be used to store database information conectado the , allow offsite personal to access database management tools and provide detailed information to customers or clients. Typical applications that use SQL databases are ERP (Enterprise Resource Planning) and CRM (Customer Relationship Management) programs.

What are the Benefits of SQL Rede Hosting

There are several advantages to investing in an SQL  hosting service rather than relying disponível  standard internet host. If you require  internet based database, you will quickly come to appreciate these benefits:

Increased RAM and Bandwidth - Typically, database applications take up  lot of memory and server space. SQL rede hosting services provide additional room for your database to evolve and grow over time.

SQL Administration Services - Because SQL internet hosting services are dedicated to database hosting, they generally have the ability to offer advanced administration services to keep your database running smoothly and at optimum performance.

Technical Assistance and SQL Desenho industrial - If you\'re new to SQL, many SQL internet hosting services provide technical assistance and configuração packages for an additional cost when you purchase rede hosting. Things to Look for in  Quality SQL Internet Hosting Service Once you\'ve decided to go with an SQL internet host, you\'ll need to select  service. There are  lot of providers currently acessível the market, and sometimes it\'s difficult to tell them apart.  quality SQL internet hosting service should offer you the following:

Reliability Control Panel Options Technical Support Customer Support Multiple Hosting Plans Overall, if you plan acessível maintaining  database disponível, your best option is to go with  internet hosting service that has servers dedicated specifically to SQL applications. Doing so will ensure that you get the most value out of your investment. SQL internet hosting may cost  little more than standard hosting, but it\'s worth every penny.

SQL Introdution

What is SQL?

SQL stands for Structured Query Language and is a declarative programming language used to access and manipulate the data in RDBMS (Relational Database Management Systems). SQL was developed by IBM in the 70's for the main unit of the platform. Several years later SQL has become the standard, therefore, the us National Institute of Standards (ANSI-SQL) and International Organization for Standardization (ISO-SQL). According to the standard ANSI SQL to pronounce "queue", but many utility and database developers with experience in MS SQL Server pronounce "sequel".

What is RDBMS?

Relational database Management System as part of utility is used to store and manage the data in the database tables objects. relational database table tabular data structure organized in rows and columns. The columns of the table, also known as table fields have unique names and different attributes defining the column type, default value, indexes and several other column characteristics. The rows of the table of the relational database are the contemporary data entries.

Most of the popular SQL RDBMS

The most popular RDBMS are MS SQL Server, Oracle, Oracle Corp., DB2 from IBM, MySQL MySQL and MS Access from Microsoft. The majority of vendors of databases, have developed their SQL property of extension based on available ANSI-standard SQL. For example, the version of SQL used by MS SQL Server is called Transact-SQL or simply T-SQL, Oracle's version is called PL/SQL (shorts for Procedural Language/SQL), and MS Access use of Jet-SQL.

What can you do with SQL?

or the SQL queries is used to retrieve data from database tables. The SQL queries use the SQL SELECT key word which is part of the data (Data Query Language dql delete). If we have the table is called "Commands" and want to select all entries where the value of the request is greater than $ 100 is ordered by the order value, you can do so with the following SQL SELECT query:

SELECT Orderid, Productid, Customerid, Orderdate, OrderValue

From the Orders

WHERE OrderValue > 200

ORDER BY OrderValue;

The SQL clause specifies which table(s) are we in the recovery of the data. SQL Where clause specifies the search criteria (in our case, to retrieve only the records with the OrderValue of more than us $200). The ORDER BY clause specifies that the returned data has to be requested by the OrderValue column. The clauses where and ORDER BY are optional.

or You can manipulate the data stored in tables of a relational database, using the INSERT, UPDATE, and DELETE SQL keywords. These three SQL commands are part of the Data Manipulation Language (DML).

– To insert data in a table named "Orders" you can use a SQL statement proximate to the bottom:

INSERT INTO Orders (Productid, Customerid, Orderdate, OrderValue)

The VALUES of (10, 108, '12/12/2007', 99.95);

- To modify the table data, you can use a statement like this:

UPDATE Orders

SET OrderValue = 199.99

WHERE CustomerID = 10 And Orderdate = '12/12/2007';

- To remove data from the database table, use the following statement:

DELETE Requests

WHERE CustomerID = 10;

or You can create, modify or delete database objects (database example of database objects (tables, views, stored procedures, etc.), through the CREATE, ALTER, and DROP SQL keywords. These three SQL keywords are part of the Data Definition Language (DDL). For example, to create the table "Orders" you can use the following SQL statement:

CREATE Orders

(

Orderid INT IDENTITY(1, 1) PRIMARY KEY,

ProductID INT,

CustomerID ID,

Orderdate DATE,

OrderValue Currency

)

or You can control the objects database privileges through the GRANTING and revocation of key-words, part of the Language, Data Control (DCL). For example, to allow the user with the user name "User1" to select the data from the table "Orders" you can use the following SQL statement:
