Query Optimization in Object—Oriented Database Systems

In this paper, query processing and optimization in object-oriented database systems (OODBs) in a centralized environment is discussed. The typical chain query processing and optimization in OODBs is investigated in detail. An algorithm with complexity of O (n3) to minimize the total cost is provided using dynamic programming, where n is the number of classes referenced by the query. Many issues are addressed and integrated into our basic formulation of the problem. These include sorted states of classes, local processing of selections and projections, allowing multiple intermediate results, arbitrary answer class, class hierarchy (which captures the IS-A relationship among objects), loop query (a simple cyclic query).
