چکیده

Object Data Management Systems (ODMSs) are a relatively new type of information management tool. They have emerged to provide support for the management of complex data in data-intensive applications like Computer-Aided Design and Computer-Aided Software Engineering. We develop an interface to an ODMS through the LOOPN++ programming language. LOOPN++ is based on Petri Nets and object-orientation, and is a useful tool for dynamically controlling data access.

ساختار دهی آنی داده‌‌های مکانی ورودی GIS با تأکید بر عارضه راه

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...

Information Systems Modelling Using Loopn++, an Object Petri Net Scheme

There have been significant recent developments in high level specification schemes for modelling information systems using formalisms based on petri nets. In particular, the application of object-based design principles have produced high level petri nets which can be used to model large complex systems. This paper discusses a new language and modelling scheme, known as LOOPN++, which fully in...

Modelling Layered Protocols in LOOPN

LOOPN is a language and simulator for specifying systems in terms of coloured timed petri nets. It includes object-oriented features such as subtyping, inheritance and polymorphism which allow for the convenient modularisation of complex specifications. This paper briefly describes LOOPN and considers its application to the modelling of layered network protocols.

Producing Network Applications Using Object-Oriented Petri Nets

The programming language Java has become and extremely popular language; many people are writing concurrent systems using Java. The design and implementation of concurrent Java programs is significantly more complex than sequential programs and the use formal method is seen as extremely beneficial for the design and implementation of such systems. The Petri net formalism [Petri 1962] can be use...
