What are the 4 Types of Databases?
The Four Types of Databases are as follows:
Operational databases
An organization’s business processes and operations rely on detailed data stored in this system. Also called subject area databases (SADBs), transactional databases, and production databases, these databases store a variety of information. Customers, human resources, inventory, and other databases containing business data are examples of operational databases. An employee database, for instance, would contain information about the employee’s hours worked, compensation, benefits, performance appraisals, training, and development status, among other things.
