What is a Relational Database?

A relational database uses tables to organize data. Data is located in tables with columns and rows and each row has a unique identifier that allows data in the row to be quickly accessed and modified. Data from different tables can be associated via a second unique identifier such as a customer or account number. The relational database type was created in 1970 by Edgar Codd at IBM’s San Jose Research Lab and it is the most popular type of database in use today. The programming language used in conjunction with relational databases is called Structured Query Language (SQL) and the database management system is called a relational database management system (RDBMS).
