Excel, Word, Access, Outlook
Previously on computer literacy: A Test For Computer Literacy
If you’re a computer programmer, you sometimes hear other programmers complain about Excel, because it mixes data and code, or about Word, because it mixes text and formatting, and nobody ever uses Word and Excel properly.
If you’re a computer programmer, you frequently hear UX experts praise the way Excel allows non-programmers to write whole applications without help from the IT department. Excel is a great tool for normal people and power users, I often hear.
I have never seen anybody who wasn’t already versed in a real programming language write a complex application in an Excel spreadsheet. I have never seen anybody who was not a programmer or trained in Excel fill in a spreadsheet and send it back correctly.
Computer programmers complain about the inaccessibility of Excel, the lack of discoverability, the mixing of code and data in documents that makes versioning applications a proper nightmare, the influence of the cell structure on code structure, and the destructive automatic casting of cell data into datatypes.
UX experts praise Excel for giving power to non-programmers, but I never met a non-programmer who used Excel “properly”, never mind developed an application in it. I met non-programmers who used SPSS, Mathematica, or Matlab properly a handful of times, but even these people are getting rarer and rarer in the age of Julia, NumPy, SymPy, Octave, and R. Myself, I have actually had to learn how to use Excel in school, in seventh grade. I suspect that half of the “basic computer usage” curriculum was the result of a lobbying campaign by Microsoft’s German branch, because we had to learn about certain features in Word, Excel, and PowerPoint on Windows 95, and non-Microsoft applications were conspicuously absent.
Visual Basic and VBS seemed like a natural choice to give power to end users in the 90s. People who had already used a home computer during the 8-bit/16-bit era (or even an IBM-compatible PC) were familiar with BASIC because that was how end-users were originally supposed to interact with their computers. BASIC was for end users, and machine code/compiled languages were for “real programmers” - BASIC was documented in the manual that came with your home computer, machine code was documented in MOS data sheets. From today’s point of view, programming in BASIC is real programming. Calling Visual Basic or .Net scripting in Excel “not programming“ misrepresents what modern programmers do, and what GUI users have come to expect after the year 2000.
Excel is not very intuitive or beginner-friendly. The “basic computer usage” curriculum was scrapped shortly after I took it, so I had many opportunities to observe people who were two years younger than me try to use Excel by experimenting with the GUI alone.
The same goes fro Microsoft Word. A friend of mine insists that nobody ever uses Word properly, because Word can do ligatures and good typesetting now, as well as footnotes, chapters, outline note taking, and so on. You just need to configure it right. If people used Word properly, they wouldn’t need LaTeX or Markdown. That friend is already a programmer. All the people I know who use Word use WYSIWYG text styling, fonts, alignment, tables, that sort of thing. In order to use Word “properly“, you’d have to use footnotes, chapter marks, and style sheets. The most “power user” thing I have ever seen an end user do was when my father bought a CD in 1995 with 300 Word templates for all sorts of occasions - birthday party invitation, employee of the month certificate, marathon completion certificate, time table, cooking recipe, invoice, cover letter - to fill in and print out.
Unlike Excel, nobody even claims that non-programmer end users do great things in Word. Word is almost never the right program when you have email, calendars, wikis, to-do lists/Kanban/note taking, DTP, vector graphics, mind mapping/outline editors, programmer’s plain text editors, dedicated novelist/screenwriting software, and typesetting/document preparation systems like LaTeX. Nobody disputes that plain text, a wiki, or a virtual Kanban board is often preferable to a .doc or .docx file in a shared folder. Word is still ubiquitous, but so are browsers.
Word is not seen as a liberating tool that enables end-user computing, but as a program you need to have but rarely use, except when you write a letter you have to print out, or when you need to collaborate with people who insist on e-mailing documents back and forth.
I never met an end user who actually liked Outlook enough to use it for personal correspondence. It was always mandated by an institution or an employer, maintained by an IT department, and they either provided training or assumed you already had had training. Outlook has all these features, but neither IT departments nor end users seemed to like them. Outlook is top-down mandated legibility and uniformity.
Lastly, there is Microsoft Access. Sometimes people confused Excel and Access because both have tables, so at some point Microsoft caved in and made Excel understand SQL queries, but Excel is still not a database. Access is a database product, designed to compete with products like dBase, Cornerstone, and FileMaker. It has an integrated editor for the database schema and a GUI builder to create forms and reports. It is not a networked database, but it can be used to run SQL queries on a local database, and multiple users can open the same database file if it is on a shared SMB folder. It is not something you can pick up on one afternoon to code your company’s billing and invoicing system. You could probably use it to catalogue your Funko-Pop collection, or to keep track of the inventory, lending and book returns of a municipal library, as long as the database is only kept on one computer. As soon as you want to manage a mobile library or multiple branches, you would have to ditch Access for a real SQL RDBMS.
Microsoft Access was marketed as a tool for end-user computing, but nobody really believed it. To me, Access was SQL with training wheels in computer science class, before we graduated to MySQL and then later to Postgres and DB2. UX experts never tout Access as a big success story in end-user computing - yet they do so for Excel.
The narrative around Excel is quite different from the narrative around Yahoo Pipes, IFTTT, AppleScript, HyperCard, Processing, or LabView. The narrative goes like this: “Excel empowers users in big, bureaucratic organisations, and allows them to write limited applications to solve business problems, and share them with co-workers.”
Excel is not a good tool for finance, simulations, genetics, or psychology research, but it is most likely installed on every PC in your organisation already. You’re not allowed to share .exe files, but you are allowed to share spreadsheets. Excel is an exchange format for applications. Excel files are not centrally controlled, like Outlook servers or ERP systems, and they are not legible to management. Excel is ubiquitous. Excel is a ubiquitous runtime and development environment that allows end-users to create small applications to perform simple calculations for their jobs.
Excel is a tool for office workers to write applications to calculate things, but not without programming, but without involving the IT department. The IT department would like all forms to be running on some central platform, all data to be in the data warehouse/OLAP platform/ERP system - not because they want to make the data legible and accessible, but because they want to minimise the number of business-critical machines and points of failure, because important applications should either run on servers in a server rack, or be distributed to workstations by IT.
Management wants all knowledge to be formalised so the next guy can pick up where you left off when you quit. For this reason, wikis, slack, tickets and kanban boards are preferable to Word documents in shared folders. The IT department calls end-user computing “rogue servers“ or “shadow IT“. They want all IT to have version control, unit tests, backups, monitoring, and a handbook. Accounting/controlling thinks end-user computing is a compliance nightmare. They want all software to be documented, secured, and budgeted for. Upper management wants all IT to be run by the IT department, and all information integrated into their reporting solution that generates these colourful graphs. Middle management wants their people to get some work done.
Somebody somewhere in the C-suite is always viewing IT as a cost centre, trying to fire IT people and to scale down the server room. This looks great on paper, because the savings in servers, admins, and tech support are externalised to other departments in the form of increased paperwork, time wasted on help hotlines, and
Excel is dominating end-user computing because of social reasons and workplace politics. Excel is not dominating end-user computing because it is actually easy to pick up for end-users.
Excel is dominating end-user computing neither because it is actually easy to pick up for non-programmers nor easy to use for end-users.
This is rather obvious to all the people who teach human-computer interaction at universities, to the people who write books about usability, and the people who work in IT departments. Maybe it is not quite as obvious to people who use Excel. Excel is not easy to use. It’s not obvious when you read a book on human-computer interaction (HCI), industrial design, or user experience (UX). Excel is always used as the go-to example of end-user computing, an example of a tool that “empowers users”. If you read between the lines, you know that the experts know that Excel is not actually a good role model you should try to emulate.
Excel is often called a “no code“ tool to make “small applications“, but that is also not true. “No Code” tools usually require users to write code, but they use point-and-click, drag-and-drop, natural language programming, or connecting boxes by drawing lines to avoid the syntax of programming languages. Excel avoids complex syntax by breaking everything up into small cells. Excel avoids iteration or recursion by letting users copy-paste formulas into cells and filling formulas in adjacent cells automatically. Excel does not have a debugger, but shows you intermediate results by showing the numbers/values in the cells by default, and the code in the cells only if you click.
All this makes Excel more like GameMaker or ClickTeam Fusion than like Twine. Excel is a tool that doesn’t scare users away with text editors, but that’s not why people use it. It that were the reason, we would be writing business tools and productivity software in GameMaker.
The next time you read or hear about the amazing usability of Excel, take it with a grain of salt! It’s just barely usable enough.

Which Is The Best PostgreSQL GUI? 2021 Comparison
PostgreSQL graphical user interface (GUI) tools help open source database users to manage, manipulate, and visualize their data. In this post, we discuss the top 6 GUI tools for administering your PostgreSQL hosting deployments. PostgreSQL is the fourth most popular database management system in the world, and heavily used in all sizes of applications from small to large. The traditional method to work with databases is using the command-line interface (CLI) tool, however, this interface presents a number of issues:
It requires a big learning curve to get the best out of the DBMS.
Console display may not be something of your liking, and it only gives very little information at a time.
It is difficult to browse databases and tables, check indexes, and monitor databases through the console.
Many still prefer CLIs over GUIs, but this set is ever so shrinking. I believe anyone who comes into programming after 2010 will tell you GUI tools increase their productivity over a CLI solution.
Why Use a GUI Tool?
Now that we understand the issues users face with the CLI, let’s take a look at the advantages of using a PostgreSQL GUI:
Shortcut keys make it easier to use, and much easier to learn for new users.
Offers great visualization to help you interpret your data.
You can remotely access and navigate another database server.
The window-based interface makes it much easier to manage your PostgreSQL data.
Easier access to files, features, and the operating system.
So, bottom line, GUI tools make PostgreSQL developers’ lives easier.
Top PostgreSQL GUI Tools
Today I will tell you about the 6 best PostgreSQL GUI tools. If you want a quick overview of this article, feel free to check out our infographic at the end of this post. Let’s start with the first and most popular one.
1. pgAdmin
pgAdmin is the de facto GUI tool for PostgreSQL, and the first tool anyone would use for PostgreSQL. It supports all PostgreSQL operations and features while being free and open source. pgAdmin is used by both novice and seasoned DBAs and developers for database administration.
Here are some of the top reasons why PostgreSQL users love pgAdmin:
Create, view and edit on all common PostgreSQL objects.
Offers a graphical query planning tool with color syntax highlighting.
The dashboard lets you monitor server activities such as database locks, connected sessions, and prepared transactions.
Since pgAdmin is a web application, you can deploy it on any server and access it remotely.
pgAdmin UI consists of detachable panels that you can arrange according to your likings.
Provides a procedural language debugger to help you debug your code.
pgAdmin has a portable version which can help you easily move your data between machines.
There are several cons of pgAdmin that users have generally complained about:
The UI is slow and non-intuitive compared to paid GUI tools.
pgAdmin uses too many resources.
pgAdmin can be used on Windows, Linux, and Mac OS. We listed it first as it’s the most used GUI tool for PostgreSQL, and the only native PostgreSQL GUI tool in our list. As it’s dedicated exclusively to PostgreSQL, you can expect it to update with the latest features of each version. pgAdmin can be downloaded from their official website.
pgAdmin Pricing: Free (open source)
2. DBeaver
DBeaver is a major cross-platform GUI tool for PostgreSQL that both developers and database administrators love. DBeaver is not a native GUI tool for PostgreSQL, as it supports all the popular databases like MySQL, MariaDB, Sybase, SQLite, Oracle, SQL Server, DB2, MS Access, Firebird, Teradata, Apache Hive, Phoenix, Presto, and Derby – any database which has a JDBC driver (over 80 databases!).
Here are some of the top DBeaver GUI features for PostgreSQL:
Visual Query builder helps you to construct complex SQL queries without actual knowledge of SQL.
It has one of the best editors – multiple data views are available to support a variety of user needs.
Convenient navigation among data.
In DBeaver, you can generate fake data that looks like real data allowing you to test your systems.
Full-text data search against all chosen tables/views with search results shown as filtered tables/views.
Metadata search among rows in database system tables.
Import and export data with many file formats such as CSV, HTML, XML, JSON, XLS, XLSX.
Provides advanced security for your databases by storing passwords in secured storage protected by a master password.
Automatically generated ER diagrams for a database/schema.
Enterprise Edition provides a special online support system.
One of the cons of DBeaver is it may be slow when dealing with large data sets compared to some expensive GUI tools like Navicat and DataGrip.
You can run DBeaver on Windows, Linux, and macOS, and easily connect DBeaver PostgreSQL with or without SSL. It has a free open-source edition as well an enterprise edition. You can buy the standard license for enterprise edition at $199, or by subscription at $19/month. The free version is good enough for most companies, as many of the DBeaver users will tell you the free edition is better than pgAdmin.
DBeaver Pricing
: Free community, $199 standard license
3. OmniDB
The next PostgreSQL GUI we’re going to review is OmniDB. OmniDB lets you add, edit, and manage data and all other necessary features in a unified workspace. Although OmniDB supports other database systems like MySQL, Oracle, and MariaDB, their primary target is PostgreSQL. This open source tool is mainly sponsored by 2ndQuadrant. OmniDB supports all three major platforms, namely Windows, Linux, and Mac OS X.
There are many reasons why you should use OmniDB for your Postgres developments:
You can easily configure it by adding and removing connections, and leverage encrypted connections when remote connections are necessary.
Smart SQL editor helps you to write SQL codes through autocomplete and syntax highlighting features.
Add-on support available for debugging capabilities to PostgreSQL functions and procedures.
You can monitor the dashboard from customizable charts that show real-time information about your database.
Query plan visualization helps you find bottlenecks in your SQL queries.
It allows access from multiple computers with encrypted personal information.
Developers can add and share new features via plugins.
There are a couple of cons with OmniDB:
OmniDB lacks community support in comparison to pgAdmin and DBeaver. So, you might find it difficult to learn this tool, and could feel a bit alone when you face an issue.
It doesn’t have as many features as paid GUI tools like Navicat and DataGrip.
OmniDB users have favorable opinions about it, and you can download OmniDB for PostgreSQL from here.
OmniDB Pricing: Free (open source)
4. DataGrip
DataGrip is a cross-platform integrated development environment (IDE) that supports multiple database environments. The most important thing to note about DataGrip is that it’s developed by JetBrains, one of the leading brands for developing IDEs. If you have ever used PhpStorm, IntelliJ IDEA, PyCharm, WebStorm, you won’t need an introduction on how good JetBrains IDEs are.
There are many exciting features to like in the DataGrip PostgreSQL GUI:
The context-sensitive and schema-aware auto-complete feature suggests more relevant code completions.
It has a beautiful and customizable UI along with an intelligent query console that keeps track of all your activities so you won’t lose your work. Moreover, you can easily add, remove, edit, and clone data rows with its powerful editor.
There are many ways to navigate schema between tables, views, and procedures.
It can immediately detect bugs in your code and suggest the best options to fix them.
It has an advanced refactoring process – when you rename a variable or an object, it can resolve all references automatically.
DataGrip is not just a GUI tool for PostgreSQL, but a full-featured IDE that has features like version control systems.
There are a few cons in DataGrip:
The obvious issue is that it’s not native to PostgreSQL, so it lacks PostgreSQL-specific features. For example, it is not easy to debug errors as not all are able to be shown.
Not only DataGrip, but most JetBrains IDEs have a big learning curve making it a bit overwhelming for beginner developers.
It consumes a lot of resources, like RAM, from your system.
DataGrip supports a tremendous list of database management systems, including SQL Server, MySQL, Oracle, SQLite, Azure Database, DB2, H2, MariaDB, Cassandra, HyperSQL, Apache Derby, and many more.
DataGrip supports all three major operating systems, Windows, Linux, and Mac OS. One of the downsides is that JetBrains products are comparatively costly. DataGrip has two different prices for organizations and individuals. DataGrip for Organizations will cost you $19.90/month, or $199 for the first year, $159 for the second year, and $119 for the third year onwards. The individual package will cost you $8.90/month, or $89 for the first year. You can test it out during the free 30 day trial period.
DataGrip Pricing
: $8.90/month to $199/year
5. Navicat
Navicat is an easy-to-use graphical tool that targets both beginner and experienced developers. It supports several database systems such as MySQL, PostgreSQL, and MongoDB. One of the special features of Navicat is its collaboration with cloud databases like Amazon Redshift, Amazon RDS, Amazon Aurora, Microsoft Azure, Google Cloud, Tencent Cloud, Alibaba Cloud, and Huawei Cloud.
Important features of Navicat for Postgres include:
It has a very intuitive and fast UI. You can easily create and edit SQL statements with its visual SQL builder, and the powerful code auto-completion saves you a lot of time and helps you avoid mistakes.
Navicat has a powerful data modeling tool for visualizing database structures, making changes, and designing entire schemas from scratch. You can manipulate almost any database object visually through diagrams.
Navicat can run scheduled jobs and notify you via email when the job is done running.
Navicat is capable of synchronizing different data sources and schemas.
Navicat has an add-on feature (Navicat Cloud) that offers project-based team collaboration.
It establishes secure connections through SSH tunneling and SSL ensuring every connection is secure, stable, and reliable.
You can import and export data to diverse formats like Excel, Access, CSV, and more.
Despite all the good features, there are a few cons that you need to consider before buying Navicat:
The license is locked to a single platform. You need to buy different licenses for PostgreSQL and MySQL. Considering its heavy price, this is a bit difficult for a small company or a freelancer.
It has many features that will take some time for a newbie to get going.
You can use Navicat in Windows, Linux, Mac OS, and iOS environments. The quality of Navicat is endorsed by its world-popular clients, including Apple, Oracle, Google, Microsoft, Facebook, Disney, and Adobe. Navicat comes in three editions called enterprise edition, standard edition, and non-commercial edition. Enterprise edition costs you $14.99/month up to $299 for a perpetual license, the standard edition is $9.99/month up to $199 for a perpetual license, and then the non-commercial edition costs $5.99/month up to $119 for its perpetual license. You can get full price details here, and download the Navicat trial version for 14 days from here.
Navicat Pricing
: $5.99/month up to $299/license
6. HeidiSQL
HeidiSQL is a new addition to our best PostgreSQL GUI tools list in 2021. It is a lightweight, free open source GUI that helps you manage tables, logs and users, edit data, views, procedures and scheduled events, and is continuously enhanced by the active group of contributors. HeidiSQL was initially developed for MySQL, and later added support for MS SQL Server, PostgreSQL, SQLite and MariaDB. Invented in 2002 by Ansgar Becker, HeidiSQL aims to be easy to learn and provide the simplest way to connect to a database, fire queries, and see what’s in a database.
Some of the advantages of HeidiSQL for PostgreSQL include:
Connects to multiple servers in one window.
Generates nice SQL-exports, and allows you to export from one server/database directly to another server/database.
Provides a comfortable grid to browse and edit table data, and perform bulk table edits such as move to database, change engine or ollation.
You can write queries with customizable syntax-highlighting and code-completion.
It has an active community helping to support other users and GUI improvements.
Allows you to find specific text in all tables of all databases on a single server, and optimize repair tables in a batch manner.
Provides a dialog for quick grid/data exports to Excel, HTML, JSON, PHP, even LaTeX.
There are a few cons to HeidiSQL:
Does not offer a procedural language debugger to help you debug your code.
Built for Windows, and currently only supports Windows (which is not a con for our Windors readers!)
HeidiSQL does have a lot of bugs, but the author is very attentive and active in addressing issues.
If HeidiSQL is right for you, you can download it here and follow updates on their GitHub page.
HeidiSQL Pricing: Free (open source)
Conclusion
Let’s summarize our top PostgreSQL GUI comparison. Almost everyone starts PostgreSQL with pgAdmin. It has great community support, and there are a lot of resources to help you if you face an issue. Usually, pgAdmin satisfies the needs of many developers to a great extent and thus, most developers do not look for other GUI tools. That’s why pgAdmin remains to be the most popular GUI tool.
If you are looking for an open source solution that has a better UI and visual editor, then DBeaver and OmniDB are great solutions for you. For users looking for a free lightweight GUI that supports multiple database types, HeidiSQL may be right for you. If you are looking for more features than what’s provided by an open source tool, and you’re ready to pay a good price for it, then Navicat and DataGrip are the best GUI products on the market.
Ready for some PostgreSQL automation?
See how you can get your time back with fully managed PostgreSQL hosting. Pricing starts at just $10/month.
While I believe one of these tools should surely support your requirements, there are other popular GUI tools for PostgreSQL that you might like, including Valentina Studio, Adminer, DB visualizer, and SQL workbench. I hope this article will help you decide which GUI tool suits your needs.

Dedicated Server Web Hosting: The Benefits And Features Of Utilizing Hosting

You've come a lengthy way out of your fledgling site that only got 200 hits monthly. You now have the 3 hundred page monster coming for you to get countless hits monthly. You are have to a much better hosting plan than you'd before. A far greater hosting plan.
Sure, your shared web hosting plan labored fine previously. Ok, well, not counting individuals intermittent lower-occasions and oh yeh, that other time if somebody (your competitors, maybe, but many likely an ex-girlfriend) determined your bank account password and deleted your whole website. However that simply won't provide for your site because it is now. You've invested a lot of time and cash into this project and it is finally beginning to yield some Fatality Servers. There's simply no question about this: you have to find and review server plans and choose the best one fast!
A passionate server is itself, the physical bit of hardware that the host company rents for you. It features its own processor, hard disk drives(s), Ram (RAM) and bandwidth capacity.
Your site and it is connected software is going to be located solely about this dedicated server's hard disk drives. Hosting permit you to install and run just about any program. They furthermore allow other users, that you have provided access, the opportunity to connect with your dedicated hosting server and employ individuals same programs simultaneously you need to do. It has made hosting extremely popular among internet gamers. Dedicated gaming servers offer the same options that come with regular dedicated hosting servers but they're meant for less serious pursuits.
But do you know the other advantages of utilizing hosting? That's certainly a legitimate question thinking about that dedicated server web hosting costs considerably greater than shared or virtual hosting plans. However with the elevated cost comes benefits and features which are considerably worthwhile.
There are lots of advantages of choosing dedicated server web hosting for the high traffic, software intensive website or gaming application. We have listed the most crucial below to influence you within the right direction.
Personalization: Most dedicated server web hosting plans permit you to fully personalize or construct your own server. You are able to therefore select and purchase just the features which you'll require. You frequently can get the selection of operating-system software (Home windows Server Edition & Linux Redhat being typically the most popular options). The selection of such software ought to be informed by thinking about which system your internet applications will run best on.
A significant feature with dedicated hosting plans can also be which user interface to make use of. Plesk and Cpanel control panels are typically the most popular choices. Both allows the hosting of multiple domains and websites but Plesk control panels have proven popular mainly due to their simplicity of use as well as their capability to facilitate event management, Postgre SQL, Support Ticketing Systems, various Language Packs and advanced dedicated game server hosting.

What is DBMS software? A Beginner’s Guide
What exactly is DBMS? We’ve told you everything you need to know about them in different articles. Today, we’re going to talk about software for managing databases. We will talk in depth about what DBMS software is and what its features are. We need DBMS software to take care of any database. Today, we’ll tell you about some well-known DBMS software that is used in web development and software development.
What is DBMS Software?
As you know, we store data in a table-like format on a computer system or server using a database. In these databases, many things are done, like adding, updating, and removing data. DBMS software is used to do all of this work.
This DBMS software is the only thing that can get into the database, get data out of it, or store data. This software acts as a link between the database and the application. When you use a web app, software, mobile app, etc., all of the data and information comes from the database, and DBMS software works between your apps and the database.
Features of DBMS Software
Real-World Item: A database management system can store any kind of information based on what the organisation needs. This doesn’t just mean names, addresses, and phone numbers. With the help of DBMS software, a database can hold any kind of data that exists in the real world.
ACID Properties: Atomicity, Consistency, Isolation, Durability, and other ACID properties can be used in database management with the help of DBMS software.
Reduces Data Redundancy: Because DBMS software follows the rules of normalisation, data redundancy, or data that is repeated in the database when it doesn’t need to be, is cut down.
Data Integrity: Data integrity is one of the most important parts of a database management system. Data integrity makes sure that the database system is good and reliable. This keeps people from getting into the database without permission and makes it safer.
Backup and Recovery: We need backup and recovery when problems like Database Failure happen. If the data couldn’t be recovered at that time, it would be a big problem. The best thing about DBMS software is that it lets you back up and restore data.
SQL ( Structured Query Language ): SQL stands for Structured Query Language. SQL is a language that can be used to create queries, insert, update, and delete data in a database. Almost all DBMS software supports SQL.
Multi-User: With DBMS software, more than one person can manage the database at the same time. It makes it easy for many people to work at the same time.
Transactions: This is a very important part of a DBMS that makes sure that a transaction is either finished or not finished, but never both. For example, if you transfer money to an account, the transaction may fail or succeed, but you won’t get half of the money.
DBMS software names
Although there are many DBMS software, but here we are going to give only the names of 10 popular DBMS software and some information about them. These are the most commonly used DBMS software.
1. Oracle RDBMS
Oracle Database is the object-relational database management software that is used the most. This tool’s most recent version is 12c, where c stands for “cloud computing.” It works on all three platforms: Windows, Unix, and Linux.
2. MySQL
MySQL is another open-source relational database management system that is used a lot (RDBMS). Many of the biggest and fastest-growing companies in the world, like Google, Facebook, Adobe, etc., use MySQL. The MySQL database management system is used by WordPress to store its blogs.
3. The SQL Server from Microsoft
One of the most popular RDBMS programmes made by Microsoft Corporation is called “SQL Server.” SQL Server works with several programming languages, such as C++, C#, Delphi, JavaScript (Node.js), PHP, and Visual Basic. SQL Server can be used on both Linux and Windows.
4. Postgre SQL
PostgreSQL is a relational database management system that is free and can be used by anyone (RDBMS). It was made at first to replace the Ingres database, which was made at the University of California, Berkeley. Many big companies, like Uber, Netflix, and Instagram, use PostgreSQL. PostgreSQL supports SQL standards, but the syntax and functions have been slightly changed.
5. MonoDB
MongoDB is an open source database management system that is based on documents and doesn’t use SQL. MongoDB Inc. offers commercial support as well as cloud database services. Most of the time, this document-oriented database software is used to store a lot of data. It works with ActionScript, C, C#, C++, Java, and JavaScript, among other programming languages. It works with Windows, Linux, OS X, and Solaris operating systems.
6. Redis
Redis is short for Remote Dictionary Server, which is its full name. It is a non-relational database system, not a relational database. Redis is often called a “data structure server” because its basic data types, such as strings, lists, dictionaries (hashes), and sets, are similar to programming languages. It also has a lot of other data types and tools for counting, geolocation, and processing streams.
7. IBM Db2
IBM made DB2, which is a relational database management system (RDBMS). DB2 is made to look at, store, and get information. With XML, it can handle both object-oriented and non-relational structures.
8. Elasticsearch
Elasticsearch is a distributed, free, and open search and analytics engine that works with all kinds of data, including textual, numerical, geospatial, structured, and unstructured data, etc. The Apache Lucene Library is the foundation for Elasticsearch. Elasticsearch is the search engine that came after Compass, which was made by Shay Banon.

Psequel alternative

#Psequel alternative how to#
#Psequel alternative update#
#Psequel alternative pro#
Easier access to files, features, and the operating system.The window-based interface makes it much easier to manage your PostgreSQL data.You can remotely access and navigate another database server.Offers great visualization to help you interpret your data.Shortcut keys make it easier to use, and much easier to learn for new users.Now that we understand the issues users face with the CLI, let’s take a look at the advantages of using a PostgreSQL GUI: I believe anyone who comes into programming after 2010 will tell you GUI tools increase their productivity over a CLI solution. Many still prefer CLIs over GUIs, but this set is ever so shrinking. It is difficult to browse databases and tables, check indexes, and monitor databases through the console.Console display may not be something of your liking, and it only gives very little information at a time.It requires a big learning curve to get the best out of the DBMS.The traditional method to work with databases is using the command-line interface (CLI) tool, however, this interface presents a number of issues: PostgreSQL is the fourth most popular database management system in the world, and heavily used in all sizes of applications from small to large. In this post, we discuss the top 6 GUI tools for administering your PostgreSQL deployments.
#Psequel alternative update#
We listen to all of our users’ feedback, put it into consideration and finally deliver a new update every week.PostgreSQL graphical user interface (GUI) tools help open source database users to manage, manipulate, and visualize their data. We response almost instantly to the bug reports, feature requests. Perhaps the best thing about being a user of TablePlus is having access to a really quick support. It has everything you need for a PostgreSQL GUI Tool. TablePlus is a modern, native tool with an elegant UI that allows you to simultaneously manage multiple databases such as MySQL, PostgreSQL, SQLite, Microsoft SQL Server and more. Then TablePlus is the app that you’re looking for.
#Psequel alternative how to#
You don’t need to be a tool expert to figure out how to use it. Has a well-thought design which works as you expected.You can be able to connect, create, update, delete, import, export… your database and its data in a very fast and secure way. An app that can be able to get up and run in less than half a second or deal with heavy operations with a couple of million rows without freezing. Was built native to deliver the highest performance.You will probably need a PostgreSQL client that: It’s time to try something new and keep up with the latest changes. Moving on with an alternative GUI tool for PostgreSQL For most people, Psequel is no longer an available GUI for PostgreSQL. In this fast-changing world where everything can be outdated easily, An app without speedy development and a frequent update schedule will never be able to deliver the best experience. It’s also closed source and the developer had stated there were no plans to open source it before disappearing. Īlthough no official statement has been issued, the development of PSequel had stopped and its issue tracker has been filled with tons of unanswered questions, bug reports, and feature requests. The latest version of PSequel which is V1.5.3 was released on. It gets SSH tunneling right while most of the others failed to do so. You can be able to do anything with your PostgreSQL database, creating, connecting, updating, deleting…, you name it. The UI is simple and elegant, just somewhat similar to Sequel Pro. It was written from scratch in Swift 2 thus it’s really neat and clean.
#Psequel alternative pro#
The main goal was just to bring the same experience of working with Sequel Pro from MySQL to PostgreSQL when Sequel Pro’s support for PostgreSQL never seems to happen.Īnd PSequel did a great job being a GUI client for Postgres. Got inspired by the simplicity and elegance of Sequel Pro, the developer behind PSequel wanted to build a PostgreSQL equivalent of it. Psequel was a great PostgreSQL GUI client.

So just type your password and press ENTER/RETURN key. My Stable Diffusion GUI update 1.3.0 is out now Includes optimizedSD code, upscaling and face restoration, seamless mode, and a ton of fixes. In the good old MySQL world, my favorite client is Sequel Pro, but its support for PostgreSQL doesn't seem to. However, they are either web-based, Java-based or don't support the features I want. I know there is a list of PostgreSQL GUI Tools. However, I found its UI is clumsy and complicated. Free Administration Centre for the PostgreSQL database. It's also one of the few clients to provide a GUI front end to the plpgsql debugger. It provides a SQL query tool, an editor for procedural languages and a CRUD interface. When you type the password, it won't be displayed on screen, but the system would accept it. Well, pgAdmin is great for its feature-richness. For many years the 'standard' freely available GUI client for Postgresql, and so is bundled in many packaged installers. If the screen prompts you to enter a password, please enter your Mac's user password to continue. No, PSequel is written from scratch in Swift 2, although PSequel's UI is highly inspired by Sequel Pro. This meant that everyone had to start pulling up Rethink docs, and learning the query syntax to update/delete/etc records, slowing down the efforts of front-end developers that otherwise don't need to know the query language.

In this blog post we discuss how you can install PostGIS on Debian 11 / Debian 10 Linux system. PostGIS is an open source extension for the powerful PostgreSQL relational database system. It enables you to create Geographic objects on the PostgreSQL database server. The features of PostGIS are derived from Open Geospatial Consortium SQL specifications. PostGIS is installable on most Linux distributions, Windows and macOS operating systems. We’ll add the PostGIS APT repository for PostgreSQL then install PostGIS on Debian system from the repository to get the latest releases of the package. Some key features of PostGIS extension are: Processing and analytic functions for both vector and raster data for splicing, dicing, morphing, reclassifying, and collecting/unioning with the power of SQL raster map algebra for fine-grained raster processing Spatial reprojection SQL callable functions for both vector and raster data Support for importing / exporting ESRI shapefile vector data via both commandline and GUI packaged tools and support for more formats via other 3rd-party Open Source tools Packaged command-line for importing raster data from many standard formats: GeoTiff, NetCDF, PNG, JPG to name a few Rendering and importing vector data support functions for standard textual formats such as KML,GML, GeoJSON,GeoHash and WKT using SQL Rendering raster data in various standard formats GeoTIFF, PNG, JPG, NetCDF, to name a few using SQL Seamless raster/vector SQL callable functions for extrusion of pixel values by geometric region, running stats by region, clipping rasters by a geometry, and vectorizing rasters 3D object support, spatial index, and functions Network Topology support Packaged Tiger Loader / Geocoder/ Reverse Geocoder / utilizing US Census Tiger data Step 1: Update system Update the package repository index by running the following commands in your terminal. sudo apt update You can install other basic tools sudo apt install wget curl gnupg2 software-properties-common apt-transport-https Step 2: Add PostgreSQL repository Pull packages signing GPG key from PostgreSQL website wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - Then add PostgreSQL repository to your Debian system: echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" |sudo tee /etc/apt/sources.list.d/pgdg.list Step 3: Install PostgreSQL Database Server PostgreSQL is required to be installed before installation of PostGIS on Debian. Use our previous guides for this installation. Install PostgreSQL 14 on Debian Install PostgreSQL 13 on Debian Once you’ve installed and configured PostgreSQL Database Server on your Debian system you can proceed with the installation of PostGIS extension. Step 4: Install PostGIS on Debian 11 / Debian 10 After the installation of PostgreSQL, proceed to install PostGIS on Debian 11 / Debian 10 Linux system. For PostgreSQL 14: sudo apt update sudo apt install postgis postgresql-14-postgis-3 For PostgreSQL 13: sudo apt update sudo apt install postgis postgresql-13-postgis-3 For PostgreSQL 12: sudo apt update sudo apt install postgis postgresql-12-postgis-3 Step 5: Enable PostGIS onDebian 11 / Debian 10 You need to activate PostGIS features on a database before you can store spacial data. The example below will show you how to create a database and activate the Spacial features. 1.Switch to postgres user. sudo -i -u postgres 2.Create test user/database. postgres@debian-bullseye-01:~$ createuser postgis_user postgres@debian-bullseye-01:~$ createdb postgis_db -O postgis_user 3.Connect to the test database: postgres@debian-bullseye-01:~$ psql -d postgis_db psql (14.1 (Debian 14.1-1.pgdg110+1)) Type "help" for help. 4.Enable the PostGIS extension on the database: postgis_db=# CREATE EXTENSION postgis; CREATE EXTENSION 5. Verify PostGIS is working postgis_db=# SELECT PostGIS_version();

Hosting dedicated servers: Benefits and features of using dedicated servers

From a website that received only two hundred visits per month, you've made a great leap. Now you have a 300-page monster that is generating millions of hits each month. A better hosting plan is required than ever before. A much better hosting plan.
Yes, your shared hosting plan was fine in the past. Okay, so that doesn't count those intermittent down-times. And, oh yeah, the other time someone (perhaps a competitor, but most likely an ex) cracked your password and deleted all your websites. This will not work for your website now. This project has been too expensive and you have finally seen results. It is clear that you must quickly find the best managed dedicated server plan and evaluate them all.
Your hosting provider rents a dedicated server, which is the actual hardware piece that you use. It is equipped with a processor, hard drives, Random Access Memory (RAM), and bandwidth capabilities. This dedicated server will host your website and any associated software. Dedicated servers enable you to install and use almost any program. You can also give other users access to your dedicated server so they can use the same programs as you. This makes dedicated servers extremely popular with internet gamers. Dedicated gaming servers provide all the same features as regular dedicated hosting servers, but are meant for more serious pursuits.
What are the other benefits to using dedicated servers? This is a valid question, considering dedicated server hosting costs are significantly higher than virtual or shared hosting plans. However, the added cost is worth the benefits and features that come with it.
Hosting dedicated servers for high-traffic, software-intensive websites or gaming applications has many advantages. Below are the main points to help you get started.
You can customize your dedicated server hosting plan. So you can choose and pay only for the features that you require. You will often be able to choose the operating system software you want (Windows Server Edition and Linux Redhat being the most common). It is important to consider which operating system will best suit your web applications before you make a decision about such software. The control panel you choose to use is a major selling point for dedicated hosting plans. Cpanel and Plesk control panels are most popular. While both panels can host multiple websites and domains, Plesk control panels are more popular due to their ease-of-use and ability to facilitate event management and Postgre SQL, Support Ticketing Systems and various Language Packs, as well as advanced dedicated server hosting.
Reliability: Your website or application is not hosted on a shared server. This means that you aren't at risk of it being overloaded by other websites and applications. The speed of your web application loading on a shared hosting plan is affected by how many visitors other websites have received from the shared hosting server. High traffic websites, and websites sharing a server, will experience slower loading times. This is avoided by dedicated server hosting which gives your web application unlimited bandwidth. Sharing hosting can be dangerous as you don't know who is uploading to the server you host on. John in Nantucket may be uploading a web app containing a virus that wipes out everything it touches. Technically, your website is on the same server that John's. Dedicated hosting eliminates this problem and allows you to sleep better at night.
Security: Only you have access to your server. There is no way for viruses or malicious software to get into your server. You can also choose to have an external firewall installed on most dedicated server plans so that you can enforce the access rights.
Unique IP Address: Each dedicated server has its own IP address. This ensures that the IP address of your domain only points to your website. Each domain and website that is hosted on a shared hosting plan receives one IP address. The server's host-header-reading software directs website traffic. Although this process is fast, it can slow down on congested shared servers. Your dedicated server will be assigned an IP address that can point only to your website or web app. Unless you host multiple websites, header-reading software will not slow down the loading process.
Upgrades, Upgrades! Your website will grow, and your budget will too. You can increase the speed of your processor and bandwidth by adding more RAM or bandwidth to your dedicated server hosting at any time. Some hosting companies will allow you switch operating systems, but this is not generally recommended. You should make a decision early on and stick with one OS. This will save you hours of tedious software conversions, and 'unexplained' downtimes.
There are other options
Hard Drive arrangement: If you've chosen to have two hard drives in your dedicated server, you can arrange them either Raid 1 (or Raid 2) Raid 1, also known as disk mirroring, allows one drive to be your primary "work from" hard drive and the other drive acts as an exact copy. This is crucial if you have sensitive information about customers or other valuable information in your web application. You can choose a Raid 2 configuration, which has a primary drive and a secondary drive. The secondary drive is used when the primary storage is full. Raid hard drives make dedicated server hosting much more reliable than regular non-dedicated server hosting.
FTP Backup: The best dedicated hosts will also offer an FTP backup account for your account. Mirroring content from your dedicated hosting server can be done in this account.
The advantages of dedicated server hosting are obvious. With this information, you can easily search for the best dedicated hosting provider. You will find all the options you need in a reliable dedicated hosting provider to make sure your website and other games run smoothly. You should only select the options that you require in a reliable dedicated host. There is no set standard for reliable dedicated servers. You must consider which options will best suit your applications. An inexpensive dedicated server with all the space, bandwidth and security features you need to run your programs efficiently is a great upgrade from a regular server hosting plan. You can customize your cheap managed dedicated servers hosting server to suit your needs and budget.
