Cohesion has been a topic of interest since structured design [20, 23] in the 1970’s. Today, there are numerous researchers continuing this work into object-oriented designs [1, 3, 5, 7, 9, 10, 12, 13, 16, 18, 19, 22]. Most of the current research has focused on the interaction of methods within a class, the inter-method cohesion. In this paper we consider both the inter-method cohesion and the...

This paper reports the results from an action research project which studies the benefits of documenting the evolution and the rationale for the evolution of a requirements specification. Earlier research into the use of ad hoc design explanation, in which design decisions were documented using the IBIS notation (Issue Based Information System) as they were made, found both benefits and weaknes...

The recent interest in object-oriented analysis has resulted in the introduction of abstraction in the analysis phase of information systems development life cycle. Abstraction has been proven to be a powerful object-oriented construct through which software complexity can be reduced and software productivity can be improved. Our main aim in this paper is to provide the support of abstraction f...

This paper presents an extended version of GoalOriented Requirements Analysis Method called AGORA, where attribute values, e.g. contribution values and preference matrices, are added to goal graphs. An analyst attaches contribution values and preference values to edges and nodes of a goal graph respectively during the process for refining and decomposing the goals. The contribution value of an ...

Improving dynamic feature of service composition is a vital and challenging stage in web service application. With the increasing of service number, it is hard to balance the flexibility and verification very well in dynamic and complex environment. The previous methods compare two services by their own features. These methods are useful and concise to find substitutes for unavailable services,...

Object–oriented methods can substantially improve achievement of software–engineering and system–building goals. Choosing a method means looking at the support it offers for the object– oriented paradigm, for the application domain of the software developer, and for software–engineering principles, practices, and goals. In this presentation we shall explore how these needs are answered by vario...

In object-oriented modeling an object reacts objectively to an invocation of one of its methods in the sense that it is given which description for the method is interpreted. Subjective behavior of an object means that is not objectively given which description is interpreted | the choice depends on other factors than the invocation such as the invoking object, the context of the objects, and t...

Object-oriented views play a key role when giving accessing applications a new or restricted perspective on persistent object-oriented data. However, traditional object-oriented view systems only allow for limited changes when it comes to restructuring a database schema and the related persistent objects in a view. We present a new approach for defining object-oriented views that enables view s...

The development of PHM propels the combination of design for testability and relevant PHM technology, which leads a need for the demonstration of PHM-oriented testability design. The paper mainly introduces the evaluation and demonstration method ranging from the design phase to the demonstration phase. Firstly, the index set to be evaluated is established according to the feature of the PHM-or...
