Object-oriented database management systems (OODBMS) are used to
imple ment and maintain large object databases on persistent
storage. Regardless whether the underlying database model follows
the object-oriented, the rela tional or the object-relational
paradigm, a key feature of any DBMS product is content based access
to data sets. On the one hand this feature provides user-friendly
query interfaces based on predicates to describe the desired data.
On the other hand it poses challenging questions regarding DBMS
design and implementation as well as the application development
process on top of the DBMS. The reason for the latter is that the
actual query performance depends on a technically meaningful use of
access support mechanisms. In particular, if chosen and applied
properly, such a mechanism speeds up the execution of predicate
based queries. In the object-oriented world, such queries may
involve arbitrarily complex terms referring to inheritance
hierarchies and aggregation paths. These features are attractive at
the application level, however, they increase the complexity of
appropriate access support mechanisms which are known to be
technically non-trivial in the relational world.
