On successful completion of this module, students will be familiar with the ideas used in database packages for personal computers and be able to design and construct a database using such a package to store and retrieve information of the type they will encounter in their studies.
This module provides an introduction to the use of a relational database management system so that:
The philosophy of the course will be to provide students with a tool and with techniques that they can use elsewhere in their studies. The practicals will be based on the microcomputer package Microsoft Access.
On successful completion of this module, students should be able to:

The views of a table; field data types, properties; validation; primary keys and indexes; Access form wizards; varieties of form available; the views of a form; controls; tab order; visual design; forms for data entry.
3. Interrogating a Database - 3 Lectures, 2 Practicals
Simple search; wildcards; filters and select queries; crosstab, parameter, groups and totals queries. Elementary SQL for queries.
4. Reports - 1 Lecture, 1 Practical
