With the popularization of information technology, workflow technology has been widely used in information, manufacturing and software fields. More and more enterprises introduce workflow engine and workflow management platform into the daily processes management. But each workflow management platform has its own requirments on business background, system environment and interfaces, which leads to the difficulty on the transplant between different companies. In this paper, referring to the reference model of workflow management platform, we developed a workflow management platform based on its business characteristics, J2EE and SOA architecture. The successful application of self-service greatly improves the operational efficiency and service levels. It is better to improve the efficiency of the inter-bank market, such as self opening accounts and information disclosure. Performance test results show that the concurrency and stability of the platform can meet the general business requirements.
