Introduction
Operational databases are used to created applications used in the
day-to-day operation of the organization. These include scheduling, invoicing,
inventory control and other applications that are considered mission critical.
They generally require a 1-3 second response time 100% of the time.
Operational databases generally use the relational database management
system, although object orientated databases are arriving on the scene.
