Data modeling at conceptual level

Lech Tuzinkiewicz

Abstract


The paper presents the process of data modeling at conceptual level. There are discussed the basic stages of the data modeling process. Key problems specific for this process are explained. Additionally the measures of quality data model evaluation are defined. Example of development of conceptual data models is shown. The way of improving the quality of the data models by using refactoring and refining is discussed.

Keywords
