I personally enjoy SQL development more than most. I interned early in my career with a team of outstanding database administrators and quickly fell in love. I had taken my database courses in school, so I had some basic knowledge, but what I learned during that internship has been invaluable to me. Not only did it teach me that I have a secret passion for data, but the technical understanding I gained has been a boon in every job I’ve gotten going forward.

However, in our industry, having full-stack skills is always a good idea. You never know what will be thrown at you. We interact with SQL daily, so more knowledge will always come in handy. Additionally, if you end up at a smaller company that does not have the resources for a full database team, more of those responsibilities will fall on you. Being able to state that you are confident in your database skills during an interview will open up many interesting career paths.

First Normal Form (1NF) states that a single field should store a single data point and that all rows should be unique. Don’t store a list of things in a field. Those should be individual records.

If you’ve taken a course on relational databases in school, you have surely encountered the term normalization. It’s the core concept of database design. However, as a developer, here’s why you should care: It will make your life easier.

The important point here is that your data should be atomic, so large tables with repeated data should be broken out into smaller tables with easily searchable keys. This makes filtering more efficient and querying more straightforward. It literally makes your job is easier!

ndemic life catching up with me. I have worked at home for years, but I was never S.T.U.C.K. at home. My now infrequent trips to Costco are the highlights of my months. I live in a nice spot — on a river — and it’s summer — but even that river life lost its glimmer for me.

Second Normal Form (2NF) states that each table should have a single primary key column. Create unique IDs. Instead of using name and address as a compound key, just give the user a unique ID number or GUID.

According to JetBrains’ 2020 Developer Ecosystem Survey, 56% of developers utilize or interact with a SQL database in their development environment. Even so, most developers view SQL concepts as a secondary concern, as they are often interacting via their chosen language and do not play much of a part in the design. Generally speaking, being able to connect and run basic queries will get you through the day.

Third Normal Form (3NF) states that no functional transitive dependencies are allowed. This one might be the most complicated, but essentially it means that if you have a field that is dependent on another field, it should be broken out to another table. This allows the foreign key to change — not the actual value.

I know when I was a teenager, I relied heavily on apps like Facebook, Skype, What’s App to communicate as I rarely had enough minutes on my phone to make calls. I remember frequently going to places like Tim Horton’s or Starbucks to use their WIFI to communicate with friends.

At many companies, there is even a separate database team that will be handling the database design and optimization, so you will never get first-hand exposure. I think this is often the deterrent to learning more about SQL. It’s viewed as a utility that is often handled by others. Software developers have enough on their plate, right? Fair enough.

The big idea behind database normalization is to reduce data redundancy and make sure that data is stored in a clean, logical manner. The level to which a database is normalized is based on which “normal form” it achieves. To date, there are debatably up to six normal forms, but in reality, all you need to understand are the first three.

There is a lot to database development and administration — there are experts out there who can work magic. However, as a developer and not an SQL wizard, these are the topics that will set you apart from the pack when it comes to SQL knowledge.
