Weiming Shen, Jean-Paul A. Barthès
1996 IFIP Advances in Information and Communication Technology  
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.  ...

Domain Centered Design Support [chapter]

Fatma Mili, Krish Narayanan
1998 Globalization of Manufacturing in the Digital Communications Era of the 21st Century  
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  ...

Lifetime dependency relationships and their application to modelling roles and relationship objects [chapter]

J. J. Kaasbøll, R. Motschnig-Pitrik
1996 IFIP Advances in Information and Communication Technology  
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.  ...  ACKNOWLEDGEMENT Thanks to Ragnar Normann, Markku Nurminen, Jan-Erik Ressem, and Gunther Vinek for constructive comments and to John Mylopoulos for insightful discussions on abstraction mechanisms.  ...

A Self-Adjusting Multi-granularity Locking protocol for Object-Oriented Databases

Deepa Saha, Joan Morrissey
2009 2009 Second International Conference on the Applications of Digital Information and Web Technologies  
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.  ...

A Review of Data Representation of Product and Process Models [chapter]

Narges Sajadfar, Yanan Xie, Hongyi Liu, Y.-S. Ma
2013 Springer Series in Advanced Manufacturing  
The B-Rep modeling method uses a model to bound the edge and vertices of the solid object in order to clearly store and speedily display geometric information, including the faces, edges, and vertices  ...  As a type of semantic data model, a product data model is a set of data in a consistent data structure that ideally represents product information efficiently, effectively, and concisely [8, 20] .  ...  A semantics-oriented engineering data repository can support the complex and dynamic engineering and business information flows among associated and networked databases in the modern economy.  ...

A multi-granularity locking model for concurrency control in object-oriented database systems

Suh-Yin Lee, Ruey-Long Liou
1996 IEEE Transactions on Knowledge and Data Engineering  
It is shown that our locking model has indeed made some improvements and is suitable for concurrency control in object-oriented databases.  ...  A locking model adopting a multi-granularity approach is proposed for concurrency control in object-oriented database systems.The model is motivated by a desire to provide high concurrency and low locking  ...  More semantic concurrency control: The semantics employed in the MGL is the relationships between objects only.  ...

Exception Handling in Object Oriented Systems [chapter]

Alexander Romanovsky, Christophe Dony, Jørgen Lindskov Knudsen, Anand Tripathi
2000 Lecture Notes in Computer Science  
Exception handling continues to be a challenging problem in object oriented system design. One reason for this is that today's software systems are getting increasingly more complex.  ...  Also, concurrency, distribution, and code mobility add new dimensions to the existing challenges in this area.  ...  This report reflects the viewpoints and ideas that were contributed and debated by all these participants. Without their contributions, neither the workshop nor this report would have materialized.  ...
