Abstract: Nowadays, distributed database (DDB) systems are often better tailored to the structure and needs of organizations than their centralized counterparts. Among the main concerns
and constraints when designing DDBs are effort and time consumption, which are limited and valuable resources. Due to the complexity of the problem, most of the proposed
solutions divide the design process into two parts: the fragmentation and the allocation of the fragments to the different locations in the network. The quality of database
distribution design, which involves fragmentation and allocation, should be assessed by the performance of a system. This paper addresses an architectural and functional
overview of an implemented tool that aids designers to design DDBs in a relational context. Conceptual design and fragmentation issues are considered as well as the
allocation problem. The tool applies metaheuristics for solving many design problems to obtain outputs in reasonable time. They use cost models and are targeted at globally minimizing these costs.
