Abstract : Since the beginning of the eighties, biological databases have considerably grown. A request on the bases which took only a few minutes can now need several days. Meanwhile, the research community in bioinformatics developped itself and specialised laboratories were created all around the world. Collaboration and exchanges between teams that were sometimes geographically very far from each other led to consider the grid as an adapted solution to the needs in computation power but also to share and distribute the biological data between the researchers. We show the interest of semi-static approaches joining data replications and task scheduling. To this end, we proceeded in three steps : a theoretical analysis, a first validation through simulations, and an implementation on a real platform. The development of this platform led to the conception of a new data manager for the DIET middleware : DAGDA. Beyond its biological applications, this data manager can meet the needs of numerous applications on computational grids
