QCF level: 3
Credit value: 6
Guided learning hours: 45

Unit aim

The aim of this unit is to enable learners to understand the features of relational databases and to develop the skills necessary to design, create and populate a relational database, as well as utilising software tools to manipulate data.

Unit introduction

Database software is one of the most commonly used application packages in business. Many jobs involve the use of databases and for this reason employees with database skills are valued. The advantages of using a relational database are extensive, including significantly reduced data storage requirements, improved record manipulation and faster access to records. As with spreadsheets, data mining software can make use of database files to interrogate records and look for trends or unusual events.

Most organisations use databases in some way to store records, for example customer information, supplier information, employee details and financial information. These records can be searched, sorted, ordered, and cross- referenced using relational databases. Using a simplified chart tool, graphs and charts can also be created and embedded in reports.

To ensure that relational databases have integrity, validity and efficiency, planning the database prior to implementation is important. Failure to do this may result in a poor product. Efficient relational database design is managed through the process of normalisation and it is important learners understand the importance this brings to developing efficient and effective databases.

In this unit learners will develop understanding of database software and principles, in order to set up an effective and efficient database. Furthermore, learners will be able to use features and functions to manipulate data to yield the desired result.
