Incorporating components from a number of different sources into a given application is generally considered to be a non-trivial activity. Over the years, various coordination mechanisms have been proposed to tackle this problem. However, even today, the question remains how to best link these coordination mechanisms with an underlying programming paradigm without loosing flexibility. A suitable technique...
Dynamic data flow analysis is a testing technique that has been successfully used for many procedural programming languages. However, for Object-Oriented (OO) programs, previous investigations have still followed a data-oriented approach to keep track of the state information for various data elements. This paper proposes an OO approach to perform dynamic data flow analysis for OO programs. In this...
Real software systems change and become more complex over time. But which parts change and which parts remain stable? Common wisdom, for example, states that in a well-designed object-oriented system, the more popular a class is, the less likely it is to change from one version to the next, since changes to this class are likely to impact its clients. We have studied consecutive releases of several...
Service oriented computing (SOC) is a paradigm for building new software applications from existing loosely-coupled services. During service composition, services available to play different roles in a composition may have variations in their business-level protocols. These protocols may involve communication between two services in a point-to-point relationship, or communication among more than two...
