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. The design tool works interactively to handle information which is ambigous, incomplete or redundant.

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.

single message and a processing mechanism that may invoke multiple methods (so long as they apply to either the input or output objects). The development of the OFD was influenced by conceptual modeling languages and discrete event simulation languages and the formal semantics of the OFD is based on work in deductive databases.

Reflection in a uniform behavioral object model,TIGUKAT object model is purely . in nature, supports full encapsulation of objects, defines a clear separation between primitive components such as ., and incorporates a . semantics over objects. The architecture of its meta-system is uniformly represented within itself, which gives a clean semantics for reflection.
