Sažetak
The increasing number of data sources that are used for decision support in business meant it was necessary to integrate all sources and their unique representation to a user. The sources we may want to integrate can be internal (local databases, etc.) or external (Internet, etc.). Each one of these sources may have a different query language, with a different syntax, different semantics and querying power. Because of this different kinds of problems may arise. The most common problems are inconsistency, partiality of data, and conflicts between sources. We need a language powerful enough to solve those problems. In this paper I will show the way to solve these problems using a logic-based language HiLog as a mediator language. Different strategies to solve these problems will be presented, as well as HiLog solutions for those strategies.
