This volume collects papers presented at the 2nd International Workshop
on Object-Oriented Database Systems (ooDBS-II) held at the Ebernburg near
Bad Münster am Stein, FRG, in September 1988. It thus gives a comprehensive
overview of the latest developments in this flourishing area of current
database research. Object-oriented database systems have been approached
with mainly two major intentions in mind, namely to better support new
application areas like CAD/CAM, office automation, knowledge engineering,
and to overcome the 'impedance mismatch' between data models and programming
languages. The notion of object-orientation in database systems is thus
a broader one than e.g. in the area of programming languages. Structural
object-orientation provides for data model mechanisms that allow the direct
representation and manipulation of highly-structured entities; behavioral
object-orientation cares for facilities to associate arbitrary user-defined
type-specific operations with data entities; finally, full object-orientation
tries to combine the advantages of both categories. Though data model concepts
are the decisive feature of object-oriented database systems, numerous
other system aspects have to be reconsidered or allow better solutions,
respectively, in this light. They include e.g. transactions, implementation
techniques, optimization, formalization, the inclusion of rules, and the
integration with other systems. A number of research prototypes and even
some commercial systems are meanwhile available. Both, approaches to extend
databases with object-oriented capabilities and approaches to extend object-oriented
programming languages with database features have been and are being investigated.
