A relational database is a type of database that stores and organizes data in tables with rows and columns, allowing users to efficiently access, update, and manage related data through established relationships between these tables.
Imagine a library with multiple shelves, each shelf containing a binder. Each binder represents a table, and inside the binders, there are pages with rows and columns. The rows represent individual records, while the columns represent the attributes of those records. Just like how you can easily find information in a library by knowing the location of the binder and the page, you can quickly access data in a relational database by knowing the table and the relationships between different tables.
A relational database is like a well-organized library of data stored in tables, with relationships between tables making it easy to find and manage information.
It's one thing to know what a relational database is, but that is worthless if you don't know why you should know what a relational database is in the first place. Let's break down the importance of this tech term based on two high-level categories. We'll walk through an explanation as well as provide a score, 1-10, that shows you how much you should care about relational databases.
If you do not have a product yet, the importance of relational databases might not be as high. At this stage, you may be more focused on ideation and planning. However, understanding the concept of relational databases can help you make informed decisions about your data storage and management strategy once you start developing your product.
If you have a live product, the importance of relational databases increases significantly.
