The fragmentation of a data warehouse into multiple data mart makes the task of the administrator very difficult. He must manage all operations of insertion, update and delete at the level of sources, Extraction, Transformation and Load (ETL) operations, logical Models, fragmentation and allocation. While nearly touching all levels of the architecture of a data warehouse, the administrator’s task is going to become especially as difficult as the level of fragmentation is raised. Of this fact, it will be interesting to develop an auto-evolutionary system permitting to maintain a data warehouse up to date without interrupting its working and while keeping all the time one same level of performance. This article presents a dynamic distributed data warehouse design, proposes some basic concepts, develops a formulation of the problem and integrates an automatic system of administration based on intelligent agents.
