Parallel query evaluation for relational database management systems still remains a challenging problem. Modern systems must show near optimal performance in spite of running in a heterogeneous hardware environment, exploiting different ways of parallelism and dealing with unpredictable system load. This thesis paper presents a dynamic and flexible system addressing the issues of optimization and evaluation of relational queries for a distributed and dynamic environment. In particular, this work consist of: 1) the architecture of a distributed system which was inspired by the concepts of software agents; 2) the architecture and the implementation of a communication infrastructure for the system components; 3) the architecture and the implementation of a new query optimization algorithm; and 4) the concept and the implementation of a new query evaluation engine for parallel execution, which enables runtime optimization of queries. Furthermore, the design supports the extension and the configuration of the system and its components.
