Abstract
In Chapter 6 we discussed a generic layering scheme for distributed query processing in which the first two layers are responsible for query decomposition and data localization. These two functions are applied successively to transform a calculus query specified on distributed relations (i.e., global relations) into an algebraic query defined on relation fragments. In this chapter we present the techniques for query decomposition and data localization.
