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

A web service is any service that is available over the Internet that uses a standardized XML messaging system which is not tied to any operating system or programming language. Web Service Security deals with quality of protection through message integrity, message confidentiality, and single message authentication. In that the well known term called WS-Security (Web Services Security) is a specification that protects SOAP messages to ensure end-to-endsecurity. To develop a secure and time effective public key cryptosystem, web services use SOAP message withMONTGOMERY’S method to improve the encryption speed enormously. Earlier RSA was chosen as a secure public key cryptosystem which has been tied up with the SOAP message communication. But the security of the RSA enabled SOAP messaging system is based on the size of the RSA key which is purely determined by the security algorithm we enforce. As the key size increases the security of the system also increases, at the same time increase in key size causes more computation time in spite of key determination.   In order to  speedup these encryption and decryption processes the new technique called Montgomery’s which performs modular multiplication and modular exponentiation and thereby improves the RSA computation much better than the usual method of computation. As an experiment we have implemented the algorithm in C#.NET and applied this algorithm over ASP.NET web service for E-Learning domain and observed that the performance of the proposed algorithm executes relatively faster than the traditional RSA algorithm.

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

Most of the E-business applications have been developed using the standard business logic model which often failed to accommodate the new changes according to the ever-changing business scenario. The end-users who are the best evaluators of E-business systems mostly depend on the QoS parameters but when it comes to the administration of the business organization the functional requirements are the one which play a major role. In order to bridge the gap between the business experts and application developer, a standard business rule mining system is needed which also has a target of managing the reconfigurable business logic with respect to the dynamic decision made by the business experts. The architecture allows the business analyst to propose new business rules for the particular business application and even reconfigure the existing rules. This mining architecture facilitates knowledge based extraction of the business rules from any given E-business applications implemented using any type of business model. For the case work we developed the architecture for E-banking application and implemented various set of banking operation services in ASP.NET. The segmented source code of targeted business logic is provided as an input for the model and it performs rule mining and generates extended business logic as output. We have also evaluated the proposed architecture using Software Architecture Analysis Method (SAAM).

Abstract

With the recent advancement in Internet technologies,and cheap availability of Internet connectivity and resources, E-learning has gained prominence among the masses. People have started preferring Virtual Learning Environments (VLE) to the traditional learning methods. The integration of E-Learning and multimedia information system has perfected and moderated its product development process to understand the user's information need and successfully links it to the appropriate information sources in order order to specialize things in learner's mind. The target of Knowledge media system is to radically enhance individual and organizational performance through integrated web-centric knowledge management, learning management, e-learning,intelligence and task support. This has forced the developers of E-learning systems to think of even more complex solutions with respect to knowledge media generation to provide the best possible learning experience to its users. This paper preciously introduces new business functions derived from traditional primitive recursive functions called Primitive Business Functions (PBF) which effectively applied to model the business logic system for the invention of new Virtual Learning Environment with high end knowledge media solution which primarily deals with Business, Learning, Delivery and Knowledge management services. The main objective of the proposed work is to analyze and identify set of computable e-learning services which in tern has set of computable business function to make interconnections between the knowledge subsystem and to provide computability, high accessibility and reusability.

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.

Abstract

In today’s highly competitive market place business analyst need to be able to cope with the growing demand for new services and react at lightning speed to new customer requirements. It has always been a question that whether the decided business logic is computable, reusable and maintainable with low cost and time.Business analyst can propose different business logic but deciding optimal business solution from the proposed logic is the key challenge where the business expert needs to concentrate on. This business logic modeling technique gives best business solution to the web service developer as a quality measure by analyzing the computational power of business functions involved in complex business logic. This paper preciously introduces new business functions derived from traditional primitive recursive function called Primitive Business Functions (PBF). PBF are mathematical functions which has recursive power and ability to act as initial, composite and recursive in nature. Primitive Business Function (PBF) breaks the complexity of complex business logic by partitioning it into number of business functions and represents them as initial, composite and μ-recursion in order to develop, reuse and maintain the web services associated with the business logic. We also provide an algorithm called Primitive Business Function Adapter Algorithm which can be easily build and adopted into N-tier service oriented E-business applications. We experimented the proposed algorithm as one of the tier in E-Banking web service development environment and observed the performance and reusable benefits of implementing decomposed business functions as web services rather than implementing the bounded business logic.

Abstract

Web services based SOA, dramatically speeding up the application development process. They also see it as a way to build applications and systems that are more adaptable. Web services are poised to have a dramatic effect on business enterprises that think of themselves as independent of technology trends. Web services are being considered an excellent technology to solve distributed computing challenges in the Internet area. So now a days Web Service discovery is an essential element in Service-Oriented Computing. But selecting appropriate web services for the benefits of service consumers is a key issue in service discovery. Web service discovery is based on service functionality and QoS. However, without Web service quality standards and quality-based discovery mechanisms, the trustworthiness of business-to-business interactions can’t be guaranteed. Web service discovery spread up into these areas like agent, ontology, semantic, context server. But even though number of techniques, methods proposed for web service is always been a question. We have wide rage of QoS parameters but it is not easy to select the best one. So we are analyzing the QoS parameters and selecting the best service according to the user request. For better decision making the Analytic Hierarchy Process (AHP), a multiple criteria decision making method, is applied as an underlying mechanism for developing a flexible and effective ranking algorithm.

Abstract

In today’s Internet driven world Web Services play a momentous role in service oriented computing providing seamless business to business interactions over Internet. Web Service Discovery is a cardinal mechanism to breakthrough the apt services which the businesses are incumbent upon. Discovering the services that meet the quality standards is a tedious task with many tradeoffs among the services like Quality of services and Cost of services. With an objective to provide quality driven web service discovery in this paper we identified several quality parameters classified under different criteria to evaluate the web services quality standards.Ranking of web services using monitored quality parameters is done through heuristic approach where in the parameters are assigned prioritized weights which meliorates the calculation of quality of services. The central theme of heuristic approach is the intelligent use of heuristic function i.e. prioritized weights to parameters to achieve the maximum efficiency in the final optimized result. We have also proposed a new architecture for evaluating the parameters and produce efficient web service discovery. We present a QoS model which is of great help in rating the web services with the end user's perspective on the basis of three levels of views, namely the business level view,Service level view and System level view.
