Abstract: We present the query processing algorithm for the Penguin system. Penguin supports multiple object views on a relational database, so that data may be shared by applications with heterogeneous object schemata. Penguin also offers an interface for the C++ language. We have developed a query processing algorithm for querying composite object views. The query algorithm takes a query on a composite object view, and decomposes it into partial queries on the relational database. The final query... (Update)
