The object-oriented data model has been utilized for geographical information applications, chiefly because of the rich set of modelling primitives it offers. Despite its representational capabilities, it still falls short in describing data typically seen in geographic information systems, i. e., impre...
Object-oriented database support for software project management environments: data-modelling issues 来自 Semantic Scholar 喜欢 0 阅读量: 50 作者: SJ Ochuodho 摘要: To keep pace with the stringent requirements of emergent applications, database technology has to change. Conventional databases have ...
Object-oriented databases have been introduced primarily to ease the development of database applications. However, the difficulties encountered when, for instance, trying to restructure data or integrate databases demonstrate that the m... S Abiteboul,A Bonner - 《Proc.acm Sigmod Int.conf.on Manage...
object oriented modelling approachobject oriented software designIn integrated CAD different techniques are used to model various features (informations, activities, data and data flow) of the problem domain. Because they model the same real world topic, all aspects developed using different techniques ...
This extended example demonstrates the applicability of OPNs to the modelling of non-trivial concurrent systems. The methodology for deriving a Petri Net model is to adapt an object-oriented design methodology: the Object Model is prepared in Rumbaugh's OMT notation; the Dynamic Model is then ...
SPATIOTEMPORAL DATA MANAGEMENT OF RECURRENT DEBRIS FLOW EVENTS USING OBJECT-ORIENTED DATA MODELLING classes have been stored and mapped using a previously proposed object-oriented and event-based model and producing in this way a multi-temporal database... M Valiante,D Guida,MF Della Seta - 《It...
It concludes with a possible application, in this case a cartographic database, explaining why the object-oriented approach is more appropriate to this application than traditional database approaches, such as the relational approach. 展开 关键词: databases object-oriented databases data modelling ...
Level-2 fuzzy sets and their usefulness in object-oriented database modelling In the real world information is, for the most part, available in an imperfect form. Managing this kind of information with classical database systems brin... Guy de Tre,RD Caluwe - 《Fuzzy Sets & Systems》 被引...
Object Oriented analysis, design and software construction should yield software of a high quality: software that is reliable, maintainable, extensible, adaptable. However, delivering large OO software systems in a qualitative way is a significant challenge. Scaling up requires formal precision o f ...
