Abstract

This paper describes the design and implementation of a kernel for an OODBMS, namely the METU Object-Oriented DBMS (MOOD). MOOD is developed on the Exodus Storage Manager (ESM). MOOD kernel provides the optimization and interpretation of SQL statements, dynamic linking of functions, and catalog management. SQL statements are interpreted whereas functions (which have been previously compiled with C++) within SQL statements are dynamically linked and executed. Thus the interpretation of functions are avoided increasing the efficiency of the system. A query optimizer is implemented by using the Volcano Query Optimizer Generator. A graphical user interface, namely MoodView, is developed using Motif. MoodView displays both the schema information and the query results graphically. Additionally it is possible to update the database schema and to traverse the references in query results graphically.
