    Scheduling Resource Usage in Object-Oriented Queries

    Database Programming Languages

    Italy. 6th - 8th September 1995


    T.W. Leung


    Query facilities in object-oriented databases lag behind their relational counterparts in performance.

    This paper identifies important sources of that performance difference, the random I/O problem and the re-reading problem.

    We propose three techniques for improving the execution of object-oriented database queries: reuse/out of order execution, memoization, and buffer replacement policy.

    Schedule level optimization is introduced as our framework for integrating these techniques into query processing systems.
