520			_aORACLE-ORACLE Corporation's database manager-is a powerful piece of software that has many capabilities. ORACLE can be used in the production environment and in the DSS environment. A previous work-ORACLE: BUILDING HIGH PERFORMANCE ONLINE SYS-TEMS, QED, 1989-explored ORACLE and high-performance, high-availability systems. This book explores ORACLE in the end-user, DSS environment. As in the case of using ORACLE to build production systems, building DSS systems begins with understanding and establishing the DSS environment. Simply taking the technology of ORACLE and building DSS systems without understanding the larger issues of the DSS environment is a prescription for disaster. The DSS environment is typified by free-form access and usage of data, high flexibility of data structures, the ability to construct sys-tems quickly, and so forth. In short, the DSS environment supports heuristic, nonrepetitive processing on which decisions about the man-agement of the company are made. But unlocking the promise of the DSS/ORACLE environment requires a thorough grounding in the is-sues of the DSS environment.
