Two points of discussion presented are whether it is possible to achieve tight coupling of the kind defined, and whether it is of some benefit to reach for tight coupling. It is concluded that in addition to a gain in performance, the tight integration of all system components will result in a homogeneous treatment of many of the application-specific system components of today. Different applications will be easier to integrate, homogeneous user interfaces will become the rule instead of the exception, and the sharing of components between different applications will reduce the system development effort considerably.<<ETX>>","PeriodicalId":329505,"journal":{"name":"[1989] Proceedings.

The report is based on extensive research experiences in specifying the structure of such a system, including the underlying data model and the privacy policy, as well as on the insight gained from a prototype implementation of selected parts of the specification. The system is called DORIS (datenschutz-orientiertes informations system). While the model is basically object-oriented, it is possible conveniently to describe an application by non-first-normal-form tuples and relations, and the data-manipulation language is high-level and relational. An expression is evaluated in three stages: navigation in the set of surrogates of persons, asking for knowledge, and finally normalization, prime value processing and output preparation. A prototype implementation of selected parts of the model is based on a kernel concept.<<ETX>>","PeriodicalId":329505,"journal":{"name":"[1989] Proceedings.
