Entity-Relationship Modeling Re-revisited
2004Since its introduction, the Entity-Relationship (ER) model has been the vehicle of choice in communicating the structure of a database schema in an implementation-independent fashion. Part of its popularity has no doubt been due to the clarity and simplicity of the associated pictorial Entity-Relationship Diagrams (“ERD’s”S) and to the dependable ...

ACM SIGMIS Database: the DATABASE for Advances in Information Systems, 1992
In the business environment data modeling diagrams are used as a user communication tool during Data Analysis, as a Database Design tool, as part of Systems Documentation and, increasingly, as a base for automatic generation of data definition language statements by CASE software.In this paper it is argued that the first two uses have conflicting ...

The entity-relationship model for multilevel security
2005A design environment for security critical database applications that should be implemented by using multilevel technology is proposed. For this purpose, the Entity-Relationship model is extended to capture security semantics. Important security semantics are defined and a language to express them in an ER model by means of security constraints is ...

Query abbreviation in the Entity-Relationship data model
Information Systems, 1994Abstract This paper examines the idea of context inference, which is the ability of a query processor to infer the appropriate relationships between the classes mentioned in a query. Context inference has been the basis of Universal Instance (UI) data models. We show that context inference can be applied to the Entity-Relationship model, resulting in
