We've just started a block of lessons on databases, and for GCSE Computing you need to know about relational databases. You can't create these in a spreadsheet application, you need a proper relational database management application, such as Microsoft Access or LibreOffice Base. It would be easiest (for me!) if we were all using the same application, so this assignment tests whether you have Access installed on your computer - it doesn't come with all versions of Micrsooft Office.
