Using PRIMA-DBMS as a testbed for parallel complex-object processing

The PRIMA-DBMS approach is explained by introducing PRIMA´s architecture and query processing framework. The PRIMA-DBMS constitutes a testbed that is flexible enough to support evaluation and validation of quite a variation of different strategies for complex-object processing taking into account different parallelization levels an different hardware environments. Thus, PRIMA marks and important step towards the authors´ main research goal concerning measures for efficient complex-object processing: the measures that are in competition with each other are query optimization, query evaluation strategies, and massive storage, that all benefit from parallelism. The programming environment that supports the parallel DBMS processing is introduced with special emphasis on its ability for parametrization and configuration. A case study of the PRIMA testbed illustrates their first investigations and demonstrates a methodology for evaluation and tuning of PRIMA configurations
