The traditional data models provide basic frameworks for database structures. However, they do not include semantic information for the representation and manipulation of databases. The data model is a representation medium concerning computer phenomena, but is not an abstraction mechanism with respect to human activities. Therefore, it is necessary to manage semantic information with a view to the intellectual information retrivals and effective database managements. In this paper, we address a semantic data model to make the intellectual database access possible. Our semantic data model is fundamentally designed on the basis of the ER model from a viewpoint of the management of semantic information. Moreover, the concept in the case grammar is introduced not only to make the properties of entities distinct, but also to interpret natural-language-like queries effectually.
