And then, we present the main features of an improved object-oriented representation model PDM and its implementation MOSS. ...
An example is given for demonstrating the application of the objectoriented representation model PDM and the object-oriented programming environment MOSS in the field of mechanical CAD. ...
Research in semantic modelling, entity-relationship modelling, or object-oriented data modelling has resulted from this interest. ...

Therefore, we seek a data model in which the structural relationship is adequately represented. Furthermore, design activities and contexts are highly dynamic. ...
In this paper we discuss mechanisms for integrating domain knowledge within design databases in ways that make it most effective for the designer, and most accessible for review and update. ...
Primitives for evolving the database model are generally limited in their expressive power and restrictive in their usage (e.g. must lock the whole database). • Rich semantics: Data in CAD systems has ...

It is argued on theoretical as well as on empirical grounds that incorporating lifetime dependency into object-oriented analysis models both improves their expressiveness and helps to keep the number of ...
One deficiency encountered in current analysis techniques is the lack of proper means to express inter-object relationships that result from dependencies of individual objects' life cycles. ...

New semantics in object-oriented databases need to be used to improve concurrency. There is still a lack of efficient concurrency control in OODBMS. ...
An object oriented database is a collection of objects and these objects' behaviour and relationship is defined according to object oriented concepts. ...
Therefore, for Typel databases the instance locking protocol will be the best choice for concurrency control and the class locking protocol will be the worst choice. ...
