RODRIGUEZ MORFFI, Abel; GARCIA GONZALEZ, Carlos Ernesto; LEMAHIEU, Wilfried  e  GONZALEZ GONZALEZ, Luisa Manuela. SIADBDD: An integrated tool to design distributed databases. Rev.fac.ing.univ. Antioquia [online]. 2009, n.47, pp.155-163. ISSN 0120-6230.

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.

Palavras-chave : Distributed Database Design; CASE tools; global conceptual schema; fragmentation; allocation.
