Title
Intra-Transaction Parallelism in the Mapping of an Object Model to a Relational Multi-Processor System
Abstract
We map an object model to a commercial relational multi-processor database system using replication and view materialisation to provide fast retrieval. To speed up complex update operations, we exploit intra-transaction parallelism by breaking such an operation down into shorter relational operations which are executed as parallel subtransactions of the update transaction. To ensure the correctness and recoverability of the operation's execution, we use multi-level transactions. In addition, we minimise the resulting overhead for the logging of the compensating inverse operation required by the multi-level concept by logging the compensation for non-derived data only. In particular, we concentrate on the novel application of multi-level transaction management to efficiently maintain the replicated data and materialised views. We present a prototype implementation and give a performance evaluation of an exemplary set-oriented update statement.
