Abstract

As the emergence of service-oriented architecture provides a major boost for e-commerce agility, the number of available Web services is rapidly increasing. However, when there are a large number of Web services available and no single Web service satisfies the given request, one has to compose multiple web services to fulfill the goal. Web services composition refers to the process of collaborating the heterogeneous web services. Even though there are many web service composition methods exist, there is no simple, standard and scalable architecture which primarily aims to satisfy the need of user request at present. This paper presents a model of web services composition by using Finite State Machine (FSM) techniques which enables to provide effective and scalable solution for service composition by generating request satisfiable deterministic paths. FSMWC targets functional, service specific and QoS attributes which when given an information goal, attempts to find all services capable of providing the desired information. We present a model for FSM based Web Service Composition (FSMWC) and evaluate the efficiency and effectiveness of FSMWC.

Abstract

Business rules have attained a major role in the development of software systems for businesses. They influence the business behavior based on the decisions enforced upon a wide range of aspects. As the business requirements are subjected to frequent amendments, new business rules have to be evolved to reinstate the previously formed ones. Business analysts count on the assistance from the IS developers for this accomplishment. As business rules are set and owned by the business, provisions must be enforced for business rule management by the business analysts directly. In order to get a clear picture of what the current policies and terms in the business are, business users utilize the document as a valuable tool. Unfortunately, documents are not updated as per the modifications in the source code. Moreover, as the software becomes larger, documents become increasingly large and hence difficult to understand and maintain. Thus they turn out to be a non-useful resource in such conditions. With a motive to resolve the above issues, several tools for extracting the rules from the business program code have been developed. In this paper, a robust architecture for an extraction engine to isolate rules from the base source code has been proposed. This suggested model involves slicing of code segments which results in easy identification of domain variables which in turn would result in extraction of business rules, validating them and exchanging them with the newly formulated business policies. This is a new research dimension which paves waves for efficient and quick business rule management strategy.

Abstract

Many organizations of the current decade use the Business Process Modeling Notation (BPMN) which is a standard for capturing business processes in the early phases of systems development. The mix of constructs found in BPMN makes it possible to create models with behavioral errors. Such errors are especially problematic at the levels of domain analysis and high-level systems design, because errors at these levels are among the hardest and most costly to correct. A methodology for monitoring the correctness and identification of the inherent properties of the process model is thus a desirable feature for modelling tools based on BPMN. Nevertheless, since prior studies have only examined issues related to semantic and functional model checking methods, there have been few researches that introduce and discuss the hidden properties and the behavioral relationships between the components of the model. In this paper, a robust architecture for business process property evaluation engine is proposed. This can be integrated with any Business Process Modeling framework to efficiently identify the isolated properties in the individual components of the model and visualize the runtime exceptions in the model. Evaluation of the proposed architecture with the help of the Architecture Tradeoff Analysis Method (ATAM) shows that using this property evaluation engine, a target system can be developed with less manpower, in less time, and with higher quality than previous methods. The property evaluation mechanism improves the earlier mode of business design and further recommends the business expert to convert the functionality into an optimized one. This is a new research dimension which paves way for the certainty of the easy maintenance and re-engineering of business processes in future.
