decision support database
Jump to user comments
A database from which data is extracted and analysed
statistically (but not modified) in order to inform business
or other decisions. This is in contrast to an operationaldatabase which is being continuously updated.
For example, a decision support database might provide data to
determine the average salary of different types of workers,
whereas an operational database containing the same data would
be used to calculate pay check amounts.
