Development of Web services-based Multidisciplinary Design Optimization framework

Ho-Jun Lee, Jae-Woo Lee, Jeong-Oog Lee
2009 Advances in Engineering Software  
Therefore, a framework that allows the implementation of MDO methods must be an environment for design synthesis.  ...  This paper proposes a Web services-based MDO framework that enables the synthesis of available disciplinary and cross-disciplinary resources for MDO via the Globus Toolkit.  ...  Requirements for building a functional MDO framework Typically, an MDO framework can be generalized to consist of the following elements: an intuitive and easy-to-use Graphical User Interface (GUI); CAD  ...

A Review of Object Oriented Database Concepts and their Implementation

Narciso Cerpa, Roy Dean
1993 Australasian Journal of Information Systems  
Object Oriented design and databases has attracted a great deal of attention in recent years.  ...  This article outlines and discusses the semantic data principles used inter alia in understanding Object Oriented concepts.  ...  For example Stonebraker, et al (1990) in their third generation manifesto of DBMS attributes, suggest a Darwinian view.  ...

A Hybrid Approach to Separation of Concerns: The Story of SADES [chapter]

Awais Rashid
2001 Lecture Notes in Computer Science  
Sina (for composition filters) [3], Demeter (for adaptive programming) [17] and AspectJ (for aspect-oriented programming) [30] were not used.  ...  One of the key motivations behind SADES was the development of an extensible and customisable object database evolution system which could be customised to the specific needs of an organisation or application  ...  It might be an error handler [29] , an update method [20] or a transformation function [9] .  ...

Designing persistence for real-time distributed object systems [chapter]

Igor Nekrestyanov, Boris Novikov, Ekaterina Pavlova
1998 Lecture Notes in Computer Science  
An implementation of persistent object store for real-time systems with strict processing time constraints is a challenging task, because many traditional database techniques, e.g. transaction management  ...  This paper examines technical and business requirements for one particular class of such systems and describes an architecture based on distributed shared virtual memory.  ...  In other words, the core engine may be considered as a real-time object-oriented DBMS with CORBA-compliant interfaces.  ...

Inheritance as an Incremental Modification Mechanism or What Like Is and Isn't Like [chapter]

Peter Wegner, Stanley B. Zdonik
1988 Lecture Notes in Computer Science  
Software components developed with an object-oriented language undergo considerable reprogramming before they become reusable in a wide range of applications or domains.  ...  This paper describes several techniques for controlling change in object-oriented systems, illustrates their functionality with selected examples and discusses their advantages and their limitations.  ...  Jason Penney and Jacob Stein, "Class Modification in the GemStone Object-Oriented DBMS," in Proceed- ings of the Conference on Object-Oriented Programming Systems, Languages, and Applications (OOPSLA  ...

Design History System: Data Models & Prototype Implementation [chapter]

Jami J. Shah, S. Rangaswamy, Sohail Qureshi, Susan D. Urban
2000 Knowledge Intensive Computer Aided Design  
This paper presents ISO/STEP compatible data models for digitally archiving the history of design projects. The two main components are a product core model and a process core model.  ...  A prototype Design History System has been implemented which can be accessed over the Internet with a web based user-interface. A relationalobject database is used for design history archival.  ...  For a particular process object and associated data objects (design specifications) there can be associated rationale and constraints.  ...

Knowledge modeling – State of the art

Vladan Devedzic
2001 Integrated Computer-Aided Engineering  
KQML is a language and a set of protocols for agent communication that supports different architectures and types of agents.  ...  Each behavior may be thought of as an individual action function that maps a perceptual input to an action to perform.  ...  The approach is based on a multilevel, general object-oriented model of intelligent systems, called OBOA (OBject-Oriented Abstraction).  ...

Graphical interaction with heterogeneous databases

T. Catarci, G. Santucci, J. Cardiff
1997 The VLDB journal  
The Graph Model has a visual syntax, so that graphical operations can be applied on its components without unnecessary mappings, and an object-based semantics. The aim of this paper is twofold.  ...  In order to address such needs we have designed a new query system with both user-oriented and multidatabase features.  ...  The authors would like to thank the anonymous referees for their helpful comments. Moreover, Tiziana Catarci and Giuseppe Santucci are grateful to Maurizio Lenzerini for his valuable suggestions.  ...

Information systems for distributed production [chapter]

Bernd E. Hirsch, Zbigniew K. Marciniak, Thorsten Kuhlmann
1995 IFIP Advances in Information and Communication Technology  
The main objective of the chapter is to design an integration system reference architecture for distributed CIM applications in a distributed production environment.  ...  As a data exchange mechanism a Common Object Request Broker Architecture is applied.  ...  Hence, it is a kind of process description. We use an object-oriented work flow model based on state diagrams for objects involved.  ...

Execution Models [chapter]

2006 Service-Oriented Computing  
This simple point illustrates a limitation of object-oriented computing. We can invoke methods on objects and, if we have the handle for an object, the object performs the method so invoked.  ...  As a result, it is straightforward for tools to generate WSDL automatically from source code, especially if it is object-oriented.  ...  Agents • If a transaction has been initiated, it will be completed. However, if an exception occurs, then it will not be completed.  ...

Types and persistence in database programming languages

Malcolm P. Atkinson, O. Peter Buneman
1987 ACM Computing Surveys  
In particular, we focus on the problems of providing a uniform type system and mechanisms for data to persist.  ...  Of particular importance in solving these problems are issues of polymorphism, type inheritance, object identity, and the choice of structures to represent sets of similar values.  ...  For example, the violation of a uniqueness constraint may raise an exception when the newPart is constructed.  ...

Upgrading a complex object DBMS to full object-orientation: a case study

H. Dentler, M. Scheurer, F. Schmid, A. Kotz, B. Schiefer, K. Dittrich
Proceedings. Second International Conference on Data and Knowledge Systems for Manufacturing and Engineering  
We claim that our approach can be regarded as a general one for non-standard DBMS kernels.  ...  The resulting DBMS is projected as a data repository for non-standard applications programmed in object-oriented as well as conventional languages.  ...  In this paper, we present an approach to build a fully object-oriented DBMS by upgrading a database system which supports complex object structures.  ...

Towards user-centric concrete model transformation

I. Avazpour
2012 2012 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)  
To generate a transformation with most current MDE approaches, users are required to specify (or provide) complex abstractions and meta-models and engage in quite lowlevel coding in usually textual transformation  ...  These abstractions are very different from concrete visual representation of source and target models and low level coding is hard to specify and maintain, especially for novice users.  ...  With regards to software engineering domain, for example, a UML class diagram is a model that describes an object oriented software system.  ...
