Sažetak
The problem of the integration of heterogeneous data sources can be divided into two separated subproblems. The first one is the problem of solving semantic inconsistencies and conflicts between independent sources. This problem is treated in [5],[6],[7] and [13]. In this paper we shall deal with the second subproblem - the problem of the translation between different query languages that data sources may use. Grammar templates for some of them will be created using DC grammars. It will be shown that DC grammars are good enough to represent all properties of query languages that are syntactically of first or higher order.
