Large commercial information systems still mainly concentrate on secondary and tertiary information rather than the goal-information actually sought by end-users. In this report, the nature of goal-information is explored and means by which it may be handled by database systems are discussed. A comparison is made of promising developments such as object-oriented databases and dynamic semantic data models with more traditional approaches using relational databases and free text retrieval systems.
