On bi-level conceptual schemas

Proceedings of the 1993 ACM conference on Computer science - CSC '93, 1993
The advent of Entity-Relationship (E-R) model has revolutionized the database design process. The overwhelming success of Entity-Relationship approach to database design partly lies in the simplicity and semantic clarity of the E-R model. However, two seemingly conflicting measurements of database design: logical-clarity and physical-efficiency, force ...

A conceptual graphs approach to conceptual schema integration

1993
The design of complex information systems usually involves the production of a number of separate conceptual design modules. These are subsequently integrated to form a global information schema. The integration of these modules is a well-known problem area in database systems design.

A method for transforming relational schemas into conceptual schemas

Proceedings of 1994 IEEE 10th International Conference on Data Engineering, 2002
A major problem with currently existing database systems is that there often does not exist a conceptual understanding of the data. Such an understanding can be obtained by describing the data using a semantic data model, such as the ER model. Consequently, there is a need for methods that translate a schema in a traditional data model into a ...

Engineering for conceptual schema flexibility

Proceedings Eleventh International Workshop on Research Issues in Data Engineering. Document Management for Data Intensive Business and Scientific Applications. RIDE 2001, 2002
Many engineering approaches exist that are widely accepted as 'good design practices' for their ability to deliver high-quality conceptual schemas. Such schemas are supposed to be stable enough for subsequent system exploitation, and flexible enough to accommodate future changes.
