Introduction Wealth Management Order Placement System (WMOPS) A global and central order placement hub in wealth management system. To provide an interface of order placement with different financial products. Event-Condition-Action (ECA) Rule a modeling approach to model the business rule in business world Help to decouple the dependency when interact with different internal system and external system WMS

Motivation and Objectives Systematic design of interactions ECA-Rule is a good approach to model Business Rule Workflow is the management of processes based on the Business Rule. Business Workflows are always complex Business Workflows can varies in different locations in a large organization Handle workflow in object-oriented approach with the properties of inheritance Workflow can plug-and-play in different location WMS

Interaction with Internal System WMS

Interaction with External System WMS

Conceptual Model of Wealth Management Order Placement Hub WMS

Conceptual Model for ECA Mechanism WMS

System Architecture of WMOPS WMS

Sequence Diagram of Order Placement WMS

Collaboration Diagram for Settlement Execution WMS

State Diagram of Order Status WMS

Deployment Diagram of WMOPS WMS

BPEL4WS of WMOPS WMS

Conclusions Event-Condition-Action (ECA) model facilitates asynchronous workflow Implementation with Web services Object-oriented modeling improve the redesign of workflow in different branches all over the world Systematic design of process for better B2B interaction Especially useful for large-scale information systems WMS

Future Work Focus on the scalability and reusability of BPEL4WS Workflow view and monitoring Handle security and transaction of workflow Study focus on semantic help on exception handling Privacy issues Conflicts between workflows Alerts and flow urgency Performance Tuning Migrate to ADOME-WFMS WMS

Question and Answer Thank you! WMS
