A Service Oriented Execution Model of Financial Online Transactions

Abstract

A business system should provide appropriate services fast enough in order to satisfy customer’s demand. It is important to integrate the resources inside an enterprise so that the development of transaction processes can be very flexibly. Service oriented architecture (SOA) is a concept which provides a methodology to deal with communications between heterogeneous distributed systems. SOA points out a new direction of the solution in system integration of existing legacy systems. The business process execution language (BPEL) can accomplish the business processes management based on SOA. The purpose of our research is to use the SOA technologies and BPEL to simplify the design of business transaction processes, especially, transaction processes of financial business. A software method to describe transaction processes of financial operations is proposed. Based on SOA and BPEL, we design a system that integrates heterogeneous platforms in a financial institution.
