Design patterns are general solutions for recurring problems and used to develop flexible, reusable and modular software with Object-Oriented Programming (OOP). Prior studies have shown a lack of modularity in object-oriented design patterns. AspectOriented Programming (AOP) aims at improving flexibility, reusability, and modularity in object-oriented designs. In a case study Hannemann and Kicz...

analysis and design of object oriented is onemodern paradigms for developing a system. in this paradigm, there are several objects and each object plays some specific roles. identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. this paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. the f...

Teaching introductory object-oriented programming presents considerable challenges. Some of these challenges are due to the intrinsic complexity of the subject matter — object-oriented concepts are tightly interrelated and appear in many combinations. The present work describes an approach to modeling educational domains and reports on the results for object-orientation. It analyzes the depende...

During the revision of Ada, the rules for object-oriented programming were carefully reviewed and tried on small examples. However, Ada 95 has now been put to use in “real” projects. Two years ago, a panel entitled “early experiences with Ada 9X program organization” described first experiences with Ada 95 using the beta version of a compiler. The goal of this panel is to renew this discussion,...

In this paper we introduce a programming language/system DK Parlog ++ which is an experimental testbed for distributed applications, particularly distributed AI and distributed knowledge base applications. The language is designed to have the concurrent computation ability of the Concurrent Logic Programming(CLP) languages, the knowledge representation and problem solving ability of Prolog, bot...

Currently, the interaction between ontologies and general purpose programming languages mostly consists of an indirect mapping between the ontology and the programming language. The language and libraries are often basically used as a programmable ontology editor. In this paper we present a different approach that creates an ontology from regular data objects in a (statically typed) mainstream ...

A visual shell, such as the Apple Macintosh Finder, is a direct manipulation interface to a le system. Although such systems are easy to use, they are are diicult to program, especially for non-programmers. This paper introduces Pursuit, a visual shell design that combines visual program speciication, visual language representation and object-oriented techniques, to address some of the problems...

Initially, object-orientation and parallelism originated and developed as separate and relatively independent areas. During the last decade, however, more and more researchers were attracted by the benefits from a potential marriage of the two powerful paradigms. Numerous research projects and an increasing number of practical applications were aimed at different forms of amalgamation of parall...

1.1 Abstract Oz is a higher-order concurrent constraint programming system under development at DFKI. It combines ideas from logic and concurrent programming in a simple yet expressive language. From logic programming Oz inherits logic variables and logic data structures, which provide for a programming style where partial information about the values of variables is imposed concurrently and in...
