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


WMS
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
APSCC 2006-2
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

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





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
