Graph Based Modeling and Implementation with EER / GRAL
نویسندگان
چکیده
This paper gives a closed approach to modeling and implementation with graphs. This approach uses extended entity relationship (EER) diagrams complemented with the Z-like constraint language GRAL. Due to the foundation of EER/GRAL on Z a common formal basis exists. EER/GRAL descriptions give conceptual models which can be implemented in a seamless manner by e cient data structures using the GraLab graph library. Descriptions of four medium size EER/GRAL-applications conclude the paper to demonstrate the usefulness of the approach in practice.

متن کاملQuerying as an Enabling Technology in Software Reengineering
In this paper it is argued that different kinds of reengineering technologies can be based on querying. Several reengineering technologies are presented as being integrated into a technically oriented reengineering taxonomy. The usefulness of querying is pointed out with respect to these reengineering technologies. To impose querying as a base technology in reengineering examples are given with...
متن کاملA Booch Metamodel a Booch Metamodel
Object-oriented methods, like the Booch method, are widely used in the development of software systems nowadays, but their syntax and semantics are only de ned by natural language text and examples. This paper provides a formalized description of the syntax of the Booch method by using the EER/GRAL approach of modeling.
متن کاملTransforming Extended Entity - Relationship Model into Object - Relational Database using Triple Graph Grammars
The entity-relationship and extended entity-relationship have been the most popular paradigms for conceptual database design. However, with the appearance of a new generation Object-relational database and UML, conceptual database modeling using the EER approach has not attracted much interest, although the EER model is still powerful when working with object-oriented databases. Therefore in th...
