Integration of Web Services and Workflow for Wealth Management Order Placement Hub

This case study explores the integration of web services and workflow within a Wealth Management Order Placement System (WMOPS) designed for international brokerages. It presents a centralized hub for order placement across various financial products, utilizing the Event-Condition-Action (ECA) model to effectively manage complex business workflows. This research highlights systematic design principles, object-oriented approaches, and the importance of scalability and reusability in developing robust B2B interactions in large-scale information systems. The findings emphasize the significance of monitoring workflows, ensuring security, and addressing privacy concerns.

  1. An Integration of Web Service and Workflow to Order Placement Hub: A Case Study on a Wealth Management System for International Brokerages

  2. 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

  3. 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

  4. Interaction with Internal System

  5. Interaction with External System

  6. Conceptual Model of Wealth Management Order Placement Hub

  7. Conceptual Model for ECA Mechanism

  8. System Architecture of WMOPS

  9. Sequence Diagram of Order Placement

  10. Collaboration Diagram for Settlement Execution

  11. State Diagram of Order Status

  12. Deployment Diagram of WMOPS

  13. BPEL4WS of WMOPS

  14. 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

  15. 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
