An Architectural Framework for Web Services Based on SOA Realization in a Bank
Abstract
SOA represents the conceptual model of an enterprise where most of the collaborating systems produce or consume services that are loosely coupled entities representing coarse grained business functions. SOA implemented using web services leverages open standards to provide a flexible model of integration without a dependency on specific implementation technology. A fundamental element of SOA is the separation of concerns between service description, implementation, binding and declarative policies governing service interactions. In this paper, we discuss the key drivers for a SOA implementation in a typical bank and introduce an architectural framework that may be followed for web service implementation in the Bank. To illustrate application of the framework, we discuss a sample web service implementation with respect to cash management.
