|The Oracle Relational Database Management System (RDBMS) is an industry
leading database system designed for mission critical data storage and
retrieval. The RDBMS is responsible for accurately storing data and efficiently

The Oracle Corporation also supplies interface tools to access data

The chief data analyst (the Pythia) would get off her skull on steam and
Laurel leaves and mutter gibberish (Said Quixotically on Laurel, SQL for
short) which was then translated by priests in an ambiguous manner in order
to please the end-user and thus extract a hefty donation.
Interbase from Borland (Unix/MS-DOS)

Probably the most famous bit of management information was to Croesus,
