Object-oriented modeling is an established approach to document information systems. In an object model, a system is captured in terms of object types and associations, state machines and collaboration diagrams, among others. Process modeling on the other hand, provides a different approach whereby behavior is captured in terms of activities, flow dependencies, resources, etc. These two approac...

As software systems become larger and more complex, developers require the ability to model abstract concepts while ensuring consistency across the entire project. The internet has changed the nature of software by increasing the desire for software deployment across multiple distributed platforms. Finally, increased dependence on technology requires assurance that designed software will perfor...

A new modeling language, called Modelica, for physical modeling is being developed in an international effort. The main objective is to make it easy to exchange models and model libraries for different domains, such as, mechanical, pneumatics, electrical, hydraulics, and others. The design approach builds on non-causal modeling with true ordinary differential and algebraic equations and the use...

Object oriented analysis OOA which is the nowadays popular approach to conceptual modeling has evolved from object oriented programming OOP and semantic data modeling SM Inheritance is one of the most important concepts of OOP Therefore an inheri tance concept suitable for OOA is needed In this paper we argue that recent approaches for semantics of inheritance in OOA are not adequate We propose...

Computer aided modeling and simulation of complex physical systems, using components from multiple domains, such as electrical, mechanical, and hydraulic, have in recent years witnessed a significant growth of interest. Generalpurpose simulation tools, e.g., Simulink, using block diagrams and causal connections have dominated the area for years. However, in the last decade novel languages, (e.g...

The Unified Modeling Language (UML) is commonly used in the development of non-real-time systems and is gaining popularity in the object-oriented real-time community as well. Recently, Rational Software Corporation teamed with ObjecTime, Ltd to develop UML for Real-Time (UML-RT). UML-RT uses the extensibility mechanisms of UML to incorporate concepts from ROOM (Real-time Object-Oriented Modelin...

Object−oriented simulation modeling and simulation Psim are presented as a powerful although basic approach to the study (or understanding) of real−time systems. The modeling approach is based on Communicating Real−Time Machines (CRSM). The modeling notation used is the set of extensions to UML (RT−UML) for real−time systems. The object−oriented simulation is the process interaction approach to...

The Enterprise Simulation Server is proposed as an ideal platform which leverages the power of the Internet for the development, execution and distribution of simulation models throughout the enterprise. The development of Javabased simulation languages is a necessary step toward the realization of this vision. The design of the new Java-based Silk simulation is described and promoted as the me...

More and more works are done on the design of the Unified Modeling Language (UML) which is designed to help us for modeling effective object oriented software , Existing ObjectOriented design methods are not mature enough to capture nonfunctional requirement such as concurrency, fault tolerance , distribution and persistence of a software approach. Our approach proposed to use aspect-oriented s...

Object-oriented database system supports the powerful concepts of data abstraction and complex data modeling while deductive database system has inferential and declarative query capabilities. Previous research has demonstrated the advantages and feasibilities of the confluence of the declarative logic-based paradigm and the object-oriented paradigm in the dual-paradigm system of deductive obje...
