Abstract

In a generalised distributed database system with decentralised controls and heterogeneous and pre-existing nodes, queries can be very complex, particularly if they provide a data integration facility. We describe here an algorithm for the optimal decomposition of such queries into subqueries, taking into consideration the availability of nodal operations (some nodes may not be able to perform all operations) and other factors. This algorithm is being implemented in the PRECI* system.
