Relational Databases

Microsoft Access - in common with most full-featured databases - has a facility which can link different databases by key fields. For example, a company may have a personnel database, sales database and a payroll database. The common field between the personnel and sales database could be an employee number, and between personnel and payroll, the National Insurance number.

An Estate Agent with a computerised system could have links between databases with a housing list, area codes, buyers, vendors etc. This type of system is called a Relational Database Management System (RDBMS).
