Application and system prototyping via an extensible object-oriented environment,this paper, we present an object-oriented design and implementation of an extensible environment for object-oriented databases. At the outset, we classify extensibility into logical and physical extensibility. We further categorize the three predominent ways to achieve the above extensibility featur作者: Dislocation 時(shí)間: 2025-3-22 08:01

Conclusion: Creation of Temporary Enclaves,which accesses information of a grammar and a lexicon is designed to meet the requirements of the tool. The parsing results are processed further on by rules and heuristics which set up a relationship between linguistic and design knowledge.

Searching for compositions in ER schemes,o an ER schema unintentionally and are hard to detect. We introduce an important class of such data, compositions of relationship sets, and define them formally. In addition, we suggest methods which might help the database designer to find compositions in the schema.作者: 波動(dòng) 時(shí)間: 2025-3-27 10:39

A taxonomy for schema versioning based on the relational and Entity Relationship Models,s which necessitate a high volume of structural changes or where structural change is difficult. This paper presents a taxonomy of changes applicable to the Entity-Relationship Model together with their effects on the underlying relational model expressed in terms of a second taxonomy relevant to the relational model.
