A New Strategy for Integrating Heterogeneous OO Schemas

In this paper, we present a strategy to integrate heterogeneous OO schemas. As compared to the existing methodologies, this approach integrates local schemas into a deductive-like global schema. In this way, more semantic relationships of component schemas can be captured and a more complete integration can be done. In addition, an efficient algorithm is proposed to do the integration automatically, based on the correspondence assertions given by designers. This algorithm is efficient in the sense that the characteristics of assertions are utilized to avoid useless matchings. 1. Introduction With the advent of applications involving increased cooperation among systems, the development of methods for integrating the pre-existing databases becomes important. The design of such global database systems must allow unified access to the diverse and possibly heterogeneous database systems without subjecting them to conversion or major modifications [BOT86, LA86, SK92, CW93, HLM94]. One impo..
