Robust Module Based Database Management System - 2517 Words

ROBUST MODULE BASED DATABASE MANAGEMENT SYSTEM ABSTRACT The present tendency for developing an ontology-based data management system (DMS) is to take advantage of on attempts made to design a preceding well-established DMS (a reference system). The method aggregates to bring out from the mention of DMS a section of schema applicable to the new application requirements – a module –perhaps personalizing it with additional-conditions w.r.t. the application under building, and then directing a dataset using the resulting schema. In this project, we expand the current denotations of modules and we inaugurate novel effects of robustness that furnish means for examine easily that a robust module-based DMS develops safely w.r.t. both the†¦show more content†¦A good implementation is consequently to build on the endeavor made to design citation DMSs whenever we have to build our own DMS with particular needs. A way to do this is to pull out from the reference DMS the section of schema related to our application requirements, possibly to customize it with extra-constraints w.r.t. our application under development, and then to direct our own dataset using the resulting schema. Latest work in description logics provides various results to fulfill such a repeat of a reference ontology-based DMS. Indeed, modern ontological languages – like the W3C advices RDFS, OWL, and OWL2 – are actually XML-based phonological variants of well-known DLs. All those results consist in taking out a section from an existing ontological schema such that all the conditions respecting the relations of absorption for the application under development are captured in the module previous definitions of sections in the literature basically spot to the notion of (deductive) conventional extension of a schema or of uniform introduce of a schema, a.k.a. omitting about non-interesting relations of a schema. Exemplify those two conceptions for schemas written in DLs and debates their connection. Till now, conventional exten sion has been
