with a full abstract specification of the data-types involved and a multi-level architecture similar to that of a DBMS. A related question is the kind of model that is most suitable for representing the architecture of documents and multimedia data. Ideally gains in flexibility and information representation resulting from the use of database techniques should not be counterbalanced by a deterioration in the human-computer interface. Besides being involved in the initial development, implementation and use of hypertext systems, members of the panel have experience in applying database techniques to textbases using ER and relational models and object-oriented approaches such as Taxis and Postgres. - 183
