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...

This paper describes the object-oriented design and implementation of an extensible schema manager for object-oriented databases. In order to achieve extensibility, we have adopted an open class hierarch y approach using an ob ject-oriented implementation where an object-oriented database maintains its implementation classes as user-defined classes. A Graphical interface for an Object-Qriented ...

In order to develop formal methods for the design, analysis and implementation of object-oriented systems it is essential to formalise the underlying object-oriented concepts. At present, most object-oriented concepts are treated informally, or are deened with reference to a particular language. The aim of this paper is to present a formal view of behavioural compatibility for classes which is ...

SOA is rapidly emerging as the premier integration and architectural approach in contemporary complex, heterogeneous computing environments. SOA is not simply about deploying software: it also requires that organizations evaluate their business models, come up with service-oriented analysis and design techniques, deployment and support plans, and carefully evaluate partner/customer/supplier rel...

SOA is a prominent paradigm for accomplishing reuse of services. Service reusability is one dominant factor which has a greater influence on achieving quality in SOA systems. There exists sufficient research in this area and researchers have contributed many works towards achieving quality in SOA systems but much emphasis was not provided on service reusability [1] [2] [3]. Few authors have add...

the present article aims to explicate the difference between perceptions of conceptual relations governing the public in different eras. therefore, this can be achieved through considering ancient greece as the birthplace of western traditions and deciphering the mythological meaning of governance in that era. to this end, it takes advantage of a hermeneutical-historical point of view to review...
