Achieving logical data independence in hypermedia databases

The authors demonstrate that the concept of logical data independence as it is used in conventional databases can be applied beneficially to hypermedia modeling to achieve a clear separation between hypermedia data and applications. They show which aspects of logical data independence can be distinguished in hypermedia databases and describe an architecture which is constructed similar to the architecture of a conventional database. The paper is a continuation of previous work, in which they described how physical data independence can be achieved for hypermedia database management systems
