IMAGE is a database management system (DBMS) developed by Hewlett-Packard and included with the HP 3000 minicomputer. It was the primary reason for that platform's success in the market. It was also sometimes referred to as IMAGE/3000 in its initial release, and later versions were known as TurboIMAGE, and TurboIMAGE/XL after the PA-RISC migration. IMAGE is based on the network database model, in contrast to most modern systems which are based on the relational database model. A SQL (Structured Query Language) front-end processor was later added, offering users the ability to run SQL queries on existing databases. This produced IMAGE/SQL, the current name.

  • DBUTIL - Creates and performs maintenance functions on the database.
