In Object-oriented databases (OODB), although path expressions through pointer connections may exist, it is sometimes necessary to perform an explicit join operation between two classes. Since a class may contain collection attributes, as well as simple attributes, join queries in OODB may be based on collections. A need for collection join algorithms arises, since conventional join algorithms, such as hybrid-hash join, GRACE join, were not designed for collection join queries. A new algorithm, so called "Parallel Double Sort-Merge" join algorithm, is proposed. This algorithm plays an important role in parallel object- oriented query processing, due to its superiority over the conventional join methods.
