We describe an integration of the hypermedia system HyperPATH with the object-oriented DBMS (OODBMS) O¡ . Providing persistence to a hypertext system was the first motivation of this work. More generally, we were interested in a better understanding of the connection of hypertext systems with OODBMS. One oals was to define an abstract interface between HyperPATH and a variety of OODBMS’s. The solution adopted shows that opening HyperPATH to different OODBMS’s is not possible without major rewriting of existing C++ code.
