Relational Databases

What is a relational database?

We use relational databases to store data that we can group into relations or tables. For example, a customer database might have a table for customers, a table for orders, and a table for product information. Each table would have a different purpose, but all data in the database would be related. Relationships are like links between tables. They allow us to connect the data from one table to another. For example, we could use a relationship to connect a customer’s name with their order information.
