1.1 INTRODUCTION
In most organizations particularly business organizations, most of what goes on consists largely of transactions. A transaction is a recorded event having to do with routine business activities. This includes everything concerning the product or service in which the organization is engaged: production, distribution, sales, order and stock-taking. It also includes the materials purchased, employees hired, taxes paid and so on. Today in most organizations, the bulk of such transactions are recorded in a computer-based information system.
