A relational database is a collection of data elements that are linked together by pre-defined relationships. These elements are laid down in a table format with columns and rows. Tables store data about the things that will be represented in the database.

 Relational Database Management System (RDBMS)?

A relational database management system (RDBMS) is a program for creating, updating, and administering relational databases.

Relational databases store data in tables. Tables can grow large and have a multitude of columns and records. Relational database management systems (RDBMSs) use SQL (and variants of SQL) to manage the data in these large tables. The RDBMS you use is your choice and depends on the complexity of your application.
