چکیده

Object-oriented computing is now an established technology for software development.However, a number of challenges must be met before the topic can claim to be fully ma-ture. One of the most demanding challenges is posed by the move from single workstationenvironments to the more general case of a distributed system. There is now considerableinterest in the distributed systems community in object-oriented techniques; it is recog-nised that the features of object-oriented computing are highly appropriate for developingcomplex distributed applications. This paper considers the importance of object-orientedtechniques to distributed system designers and discusses the repercussions of such a moveto distributed environments. The impact of distribution on object-oriented computing isexamined in depth. This analysis raises a number of important issues such as the needfor a broader view of object-oriented computing and the requirement for exible approach-es to invocation. Problems relating to persistence and distribution transparency are alsodiscussed. The importance of underlying system support for distributed objectorientedcomputing is stressed and a case study of the Chorus/ COOL environment presented. Thepaper concludes by assessing the state of the art in distributed object-oriented computing.It is argued that further research is required before the advantages of the object-orientedapproach to software development can be realised in a distributed environment.

Objects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques

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...

On Attributes of Objects in Object-Oriented Software Analysis

One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...

Declarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey

One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...
