- W204065736 abstract "High-quality designing of present-day information systems is not possible without using conceptual modeling techniques. They allow to decrease complexity of processed information noticeably, and to focus on key aspects of a system being created. But now complexity of systems is so high that their representation as a conceptual model has high complexity too. There is several approaches to control of conceptual model complexity, for example, adding abstraction layers. In this paper we suggest an original method that may be used along with existing ones. Essence of the method lies in not using self-dependent identification of relations. An object type set underlying a relation is suggested to be used as its identifier. The article considers the consequences of this step: simplification of conceptual model analysis, completeness of relation’s semantics; it is shown possibility of development of a conceptual query language expressions of which do not refer to relations in an explicit way, are compact, and, at the same time, have structure that is very close to phrases of natural language (without any artificial additions). The paper gives prove that the suggested approach to control of conceptual model complexity does not result in significant effort increasing in the course of conceptual designing, and that it is applicable in all the cases in which other conceptual techniques are applicable." @default.
