Before You Code, ensure to do this

As developers, it’s tempting to dive straight into coding, but hold on a second! Before you do, there’s one critical step you should never skip: planning your data entities and their relationships.

The first problem your app will likely encounter isn’t about the framework or language used, it’s about your database and the organization of your data. Trust me, a well-thought-out schema can save you countless headaches down the line.

Picture this: You’re at an event planning for 500 guests, but only 50 show up. You’ve got all this excess capacity, right? That’s what happens when you define a column to hold 1000 characters as LONGTEXT. It’s wasteful. Instead, use TEXT, which can handle up to 65k+ characters.

Understanding your data types and their ranges is crucial. For example:

VARCHAR is perfect for 1 to 255 characters.
TEXT or MEDIUMTEXT is your go-to for up to 65,535 characters.
Know when to use TINYINT, SMALLINT, or INT based on the range of values each can hold.

I’ve seen schemas where columns were over-provisioned, like a column defined as LONGTEXT for data that never exceeds 1000 characters. This is inefficient. Just like you wouldn’t rent a stadium for a small gathering, don’t over-allocate your data types.

And don’t forget about signed vs. unsigned integers. If you need to store a number that can never be negative, say from 0 to 200, go for an unsigned TINYINT. This not only ensures data integrity but also optimizes performance.

In short, a little planning goes a long way. Understanding your data and choosing the right types can drastically improve your app’s efficiency and maintainability.

Happy coding, and remember: A solid foundation is key to a successful build
