Theory
1. Introduction
There are a lot of new terms to learn when you begin to cover the database section at AS level ICT.
You will be expected to know, understand and use correct database terminology when answering questions in your examination.
Some of these terms that you must understand and be able to use are entities and attributes.
You must also understand how to draw and interpret an entity relationship (E-R) diagram.
This theory will be covered in the next few pages.
Use the menu on the left-hand side to navigate through the pages. Then have a go at the workbook provided in the tasks section of this site.
