MySQL Naming Conventions

What is MySQL?

MySQL is a freely available open source Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). SQL is the most popular language for adding, accessing and managing content in a database. It is most noted for its quick processing, proven reliability, ease and flexibility of use.

What is a naming convention?

In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers that denote variables, types, functions, and other entities in source code and documentation.

General rules — Naming conventions

Using lowercase will help speed typing, avoid mistakes as MYSQL is case sensitive.

Space replaced with Underscore — Using space between words is not advised.

Numbers are not for names — While naming, it is essential that it contains only Alpha English alphabets.

Valid Names — Names should be descriptive of the elements. i.e. — Self-explanatory and not more than 64 characters.

No prefixes allowed.

Database name convention

Name can be singular or plural but as the database represents a single database it should be singular.

Avoid prefix if possible.

MySQL table name

Lowercase table name

MySQL is usually hosted in a Linux server which is case-sensitive hence to stay on the safe side use lowercase. Many PHP or similar programming frameworks, auto-detect or auto-generate class-based table names and most of them expect lowercase names.

Table name in singular

The table is made up of fields and rows filled with various forms of data, similarly the table name could be plural but the table itself is a single entity hence it is odd and confusing. Hence use names like User, Comment.

Prefixed table name

The table usually has the database or project name. sometimes some tables may exist under the same name in the database to avoid replacing this, you can use prefixes. Essentially, names should be meaningful and self-explanatory. If you can’t avoid prefix you can fix it using php class.

Field names

Use all above cases which include lowercase, no space, no numbers, and avoid prefix.

Choose short names no-longer than two words.

Field names should be easy and understandable

Primary key can be id or table name_id or it can be a self-explanatory name.

Avoid using reserve words as field name. i.e. — Pre-defined words or Keywords. You can add prefix to these names to make it understandable like user_name, signup_date.

Avoid using column with same name as table name. This can cause confusion while writing query.

Avoid abbreviated, concatenated, or acronym-based names.

Do define a foreign key on database schema.

Foreign key column must have a table name with their primary key.

e.g. blog_id represents foreign key id from table blog.

Avoid semantically — meaningful primary key names. A classic design mistake is creating a table with primary key that has actual meaning like ‘name’ as primary key. In this case if someone changes their name then the relationship with the other tables will be affected and the name can be repetitive losing its uniqueness.

Conclusion

Make your table and database names simple yet understandable by both database designers and programmers. It should things that might cause confusion, issues with linking tables to one another. And finally, it should be readable for programming language or the framework that is implemented.

🎉 Just finished reading this awesome adventure in database design! If you're into tech and love a good challenge, check out this post on database normalization. It's a fun and insightful read that turns a complex topic into a captivating story. 🚀📊

The Great Data Cleanup: A Database Design Adventure

As a budding database engineer, I found myself in a situation that was both daunting and hilarious. Our company's application was running slower than a turtle in peanut butter, and no one could figure out why. That is, until I decided to take a closer look at the database design.

It all began when my boss, a stern woman with a penchant for dramatic entrances, stormed into my cubicle. "Listen up, rookie," she barked (despite the fact that I was quite experienced by this point). "The marketing team is in an uproar over the app's performance. Think you can sort this mess out?"

Challenge accepted! I cracked my knuckles, took a deep breath, and dove headfirst into the database, ready to untangle the digital spaghetti.

The schema was a sight to behold—if you were a fan of chaos, that is. Tables were crammed with redundant data, and the relationships between them made as much sense as a platypus in a tuxedo.

"Okay," I told myself, "time to unleash the power of database normalization."

First, I identified the main entities—clients, transactions, products, and so forth. Then, I dissected each entity into its basic components, ruthlessly eliminating any unnecessary duplication.

For example, the original "clients" table was a hot mess. It had fields for the client's name, address, phone number, and email, but it also inexplicably included fields for the account manager's name and contact information. Data redundancy alert!

So, I created a new "account_managers" table to store all that information, and linked the clients back to their account managers using a foreign key. Boom! Normalized.

Next, I tackled the transactions table. It was a jumble of product details, shipping info, and payment data. I split it into three distinct tables—one for the transaction header, one for the line items, and one for the shipping and payment details.

"This is starting to look promising," I thought, giving myself an imaginary high-five.

After several more rounds of table splitting and relationship building, the database was looking sleek, streamlined, and ready for action. I couldn't wait to see the results.

Sure enough, the next day, when the marketing team tested the app, it was like night and day. The pages loaded in a flash, and the users were practically singing my praises (okay, maybe not singing, but definitely less cranky).

My boss, who was not one for effusive praise, gave me a rare smile and said, "Good job, rookie. I knew you had it in you."

From that day forward, I became the go-to person for all things database-related. And you know what? I actually enjoyed the challenge. It's like solving a complex puzzle, but with a lot more coffee and SQL.

So, if you ever find yourself dealing with a sluggish app and a tangled database, don't panic. Grab a strong cup of coffee, roll up your sleeves, and dive into the normalization process. Trust me, your users (and your boss) will be eternally grateful.

Step-by-Step Guide to Database Normalization

Here's the step-by-step process I used to normalize the database and resolve the performance issues. I used an online database design tool to visualize this design. Here's what I did:

Original Clients Table:

ClientID int

ClientName varchar

ClientAddress varchar

ClientPhone varchar

ClientEmail varchar

AccountManagerName varchar

AccountManagerPhone varchar

Step 1: Separate the Account Managers information into a new table:

AccountManagers Table:

AccountManagerID int

AccountManagerName varchar

AccountManagerPhone varchar

Updated Clients Table:

ClientID int

ClientName varchar

ClientAddress varchar

ClientPhone varchar

ClientEmail varchar

AccountManagerID int

Step 2: Separate the Transactions information into a new table:

Transactions Table:

TransactionID int

ClientID int

TransactionDate date

ShippingAddress varchar

ShippingPhone varchar

PaymentMethod varchar

PaymentDetails varchar

Step 3: Separate the Transaction Line Items into a new table:

TransactionLineItems Table:

LineItemID int

TransactionID int

ProductID int

Quantity int

UnitPrice decimal

Step 4: Create a separate table for Products:

Products Table:

ProductID int

ProductName varchar

ProductDescription varchar

UnitPrice decimal

After these normalization steps, the database structure was much cleaner and more efficient. Here's how the relationships between the tables would look:

Clients --< Transactions >-- TransactionLineItems

Clients --< AccountManagers

Transactions --< Products

By separating the data into these normalized tables, we eliminated data redundancy, improved data integrity, and made the database more scalable. The application's performance should now be significantly faster, as the database can efficiently retrieve and process the data it needs.

Conclusion

After a whirlwind week of wrestling with spreadsheets and SQL queries, the database normalization project was complete. I leaned back, took a deep breath, and admired my work.

The previously chaotic mess of data had been transformed into a sleek, efficient database structure. Redundant information was a thing of the past, and the performance was snappy.

I couldn't wait to show my boss the results. As I walked into her office, she looked up with a hopeful glint in her eye.

"Well, rookie," she began, "any progress on that database issue?"

I grinned. "Absolutely. Let me show you."

I pulled up the new database schema on her screen, walking her through each step of the normalization process. Her eyes widened with every explanation.

"Incredible! I never realized database design could be so... detailed," she exclaimed.

When I finished, she leaned back, a satisfied smile spreading across her face.

"Fantastic job, rookie. I knew you were the right person for this." She paused, then added, "I think this calls for a celebratory lunch. My treat. What do you say?"

I didn't need to be asked twice. As we headed out, a wave of pride and accomplishment washed over me. It had been hard work, but the payoff was worth it. Not only had I solved a critical issue for the business, but I'd also cemented my reputation as the go-to database guru.

From that day on, whenever performance issues or data management challenges cropped up, my boss would come knocking. And you know what? I didn't mind one bit. It was the perfect opportunity to flex my normalization muscles and keep that database running smoothly.

So, if you ever find yourself in a similar situation—a sluggish app, a tangled database, and a boss breathing down your neck—remember: normalization is your ally. Embrace the challenge, dive into the data, and watch your application transform into a lean, mean, performance-boosting machine.

And don't forget to ask your boss out for lunch. You've earned it!

Blog #11 – Oral Recitation: ERD, Normalization, and the Data Dictionary

For this week’s blog, we had an oral recitation covering three important database design topics: Entity Relationship Diagram (ERD), Database Normalization, and the Data Dictionary. What made this recitation unique was the use of a module roulette, where questions were randomly selected from Modules 7, 8, and 9. The exciting twist? We were allowed to use our notes, and those who raised their hands first had the chance to answer!

Here’s a quick recap of what we covered:

📌 Module 7 – Entity Relationship Diagram (ERD): An ERD is a visual representation of the system’s data structure. It maps out key entities—like users, records, or transactions—and the relationships between them. Using symbols like rectangles (for entities) and diamonds (for relationships), the ERD helps developers and stakeholders understand how the database is structured and how different components interact.

📌 Module 8 – Database Normalization: This process ensures that data is well-organized and free from redundancy. Normalization involves dividing tables into smaller, related ones and defining relationships between them. It’s essential for eliminating anomalies (like insert, update, or delete issues) and maintaining data integrity across the system.

📌 Module 9 – Data Dictionary: The Data Dictionary is a text-based reference that describes all the data elements in a system—like field names, data types, relationships, and constraints. It acts as a central guide for developers, helping maintain consistency and clarity when designing or updating databases.

I’m happy to share that I passed the oral recitation and met the score requirements! 😊 It feels great to see hard work and preparation pay off, especially when discussing topics that will play a big role in our ongoing research project.

Excited to keep building on this knowledge as we continue with our manuscript and system design!

Data Security in Database Design: Protecting Your Information from Threats and Attacks

Data security is a critical concern for any organization that handles sensitive information. Database design plays a crucial role in protecting data from various threats and attacks. Here are some best practices to ensure data security in database design:

Access control: Limit access to the database to authorized users only. Use strong authentication mechanisms, such as passwords or biometrics, to ensure that only legitimate users can access the data.

Encryption: Use encryption techniques to protect data at rest and in transit. Encryption can prevent unauthorized access to sensitive information, even if attackers gain access to the database.

Data masking: Implement data masking techniques to hide sensitive information from users who do not need to see it. This can include techniques such as replacing sensitive data with random characters or masking certain characters.

Regular backups: Make regular backups of the database and store them in a secure location. This ensures that data can be recovered in case of a disaster or data breach.

Vulnerability testing: Regularly test the database for vulnerabilities and address any issues promptly. This can include scanning for vulnerabilities in the database software, as well as testing the security of the underlying infrastructure.

Security patches: Keep the database software up-to-date with the latest security patches and updates. This can help prevent known vulnerabilities from being exploited by attackers.

Monitoring and logging: Implement monitoring and logging mechanisms to track who is accessing the database and what they are doing. This can help identify potential threats and suspicious behavior.

Regular training: Train database users on best practices for data security, including how to create strong passwords, how to identify phishing emails, and how to report suspicious activity.

By following these best practices, organizations can improve data security in their database design and protect their sensitive information from various threats and attacks.
