Summary

This new unit covers everything in Section 3.7 of the latest AQA 8525 specification. It begins by covering the concept of a database before extending this into relational databases and associated terminology. Inconsistency and redundancy are covered before looking at Structure Query Language (SQL). SQL is used to write and interpret simple queries and to insert, update or delete data from a database table.
