VERSION SUPPORT FOR ENGINEERING DATABASE-SYSTEMS

In engineering applications, multiple copies of object descriptions have to coexist in a single database. This paper proposes a scheme that enables users to explicitly deal with these object versions. After introducing a basic version model, the problem of 'rerouting' interobject references upon the creation of new versions is solved by providing generic references and user-specific environments. Finally, logical version clusters are introduced that allow for the meaningful grouping of versions. The paper concludes with some remarks on implementation and a comparison with other approaches.

CSDL: A Conceptual Schema Definition Language for the design of Data Base Applications

引用

IEEE Transactions on Software Engineering 1979年第5期SE-5卷 481-496页

作者： Roussopoulos, Nicholas Department of Computer Sciences University of Texas at Austin Austin TX. 78712 United States

A language to support the incremental design of the conceptual schemata of data bases is presented. Abstractions are expressed in terms of highevel constructs and operations on these abstractions allow the definition of other abstractions. Both abstractions and operations on them are totally independent from the underlying internal representation of the schema, which is created consistently by applying the operators of the language. In addition, the language offers a number of support facilities for type checking of relationships and graphical displays of the conceptual schemata for easier understanding.
