Do you use the internet to search for information, such as music tracks, items in an online shop or train times? If so, the chances are that you are using a database without realising it! Many IT systems involve the use of databases and it is important to understand how they work.

Databases are designed to hold data in a digital form, for example, a record for each computer game in a shop. Database tools can be used to ensure the data is valid and accurate.

They also allow information to be restricted to certain individuals and to be analysed and presented in reports. Job roles include database administrators who oversee the performance, integrity and security of a system and database managers who are responsible for the way a company manages, organises and stores its information.

In this unit you will investigate the features and uses of databases by exploring what they are and what you can do with them. You will be able to apply some of your findings to your own database solution.

You will also learn how to use database software to design, develop and test relational databases for a brief. Once completed, you will review your database, having obtained feedback from others, and evaluate possible improvements.
