RESTful Web Services vs. ``Big'' Web Services: Making the Right Architectural Decision

Web services are proposed as a way to enable loosely-coupled integration of business processes of different stakeholders. This requires effective development mechanisms that focus on modeling of business logic rather than on low-level technical details. This problem has been recognized by several researchers, and they have mainly proposed the use of process-oriented languages e. However, process-oriented approaches limit the definitions of Web services only to the context of concrete business processes where the services are used. To overcome this limitation, in this paper, we propose a modeling approach that enables one to model Web services from the perspective of the underlying business logic regulating how Web services are used regardless of the context where they are used. By leveraging the principles of model-driven engineering, we define a rule-based modeling language supporting the proposed modeling approach.

XML: The Three Revolutions As Figure below attached illustrates, the three areas of impact are data, which XML frees from the confines of fixed, program-dependent formats; architecture, with a change in emphasis from tightly coupled distributed systems to a more loosely coupled confederation based on the Web; and software, with the realization that software evolution is a better path to managing complexity than building monolithic applications.

RESTful Web Services vs. “Big” Web Services: Making the Right Architectural Decision

Distribution of these papers is limited to classroom use, and personal use by others. REST debate by giving a quantitative technical comparison based on architectural principles and decisions. We show that the two approaches differ in the number of architectural decisions that must be made and in the number of available alternatives. This discrepancy between freedom-from-choice and freedom-of-choice explains the complexity difference perceived. However, we also show that there are significant differences in the consequences of certain decisions in terms of resulting development and maintenance costs. Many different styles can be used to integrate enterprise applications Figure 1. The choice between relying on a shared database , using batched file transfer , calling remote procedures , or exchanging asynchronous messages over a message bus is a major architectural decision, which influences the requirements for the underlying middleware platform and the properties of the integrated system [ 20 ].

May 19, Of course the first organization within the insurance industry to turn to accomplish this goal was the Association for Cooperative Operations Research and Development, which is a nonprofit membership organization aimed at developing data standards for the insurance industry. Since , ACORD has been very involved in standardizing the way insurance businesses run, from when a potential customer walks into an insurance office, all the way through to claims and the way that transactions are communicated back and forth among major carriers, brokerages, agents, and so on. Initially the organization focused on standardizing insurance forms, and then moved on to pass data standards for insurance transaction processing. PressPass: Can you elaborate more on the need for such a solution? What are some of the technology challenges the industry faces?
