Abstract

In the context of the project HEaD (Heterogeneous Extensibleand Distributed DBMS) we present a technology to distributejoin queries over distributed relational DBMSs in a heterogeneous workstation network. Special aspects are the optimization of multi-way joins and the optimal parallel execution based on data flow control involving CPU, I/O, memory allocation and network load. We focus our attention on spanning a complete search space without invalid elements to optimize multi-way joins with help of an approximative search algorithm and a complex cost function.
