Parallelization and object-orientation: a database processing point of view

To improve the performance of object-oriented databases, we wish to create some integration between parallel and object-oriented technologies. We concentrate on path expression queries. The parallelization of path expression queries can be achieved through simultaneous processing among objects (inter-object parallelization), or concurrent processing among classes (inter-class parallelization). These two parallelization models view parallel object-oriented query processing from two different angles, the object point of view and the class point of view. We also present performance measurements for an implementation which highlight the strengths and the weaknesses of each parallelization model.
