Starting point to implement Reference Architecture

Business Entities

Service Interface• Dynamic interface• Uses ProDatasets

OpenEdge Reference Implementation

fetchWhere• Retrieves Dataset with customer records• Optional filter

saveChanges• Uses Dataset to pass in creates, updates and

deletes on customer records

validateCustomer• Validation logic using error flags on Dataset

Dynamic Service Interface• Single point of entry into system• Same signature for all exposed methods

– Using Datasets

Core services• Session• Context• Security• Service Registry

Sending messages• Extend Business Entity• Send out Sonic message when records are

changed

Receiving messages• Receive messages with changes• Call existing business entity to validate and

apply changes

Sending messages

saveChanges in beCustomer.p• Send message with new customer data• Send message with changed customer data• Send message with customer deletes

Message• Includes XML with customer data• Includes property to indicate add/change or

delete• Includes properties to find Business Entity

Sample Message

saveChanges and sending messages

Need separate send for updates/adds vs deletes• Dataset handling of deletes

Adds / updates• Need to after the Data Access layer

Deletes• Need to happen before the Data Access layer• Need to look at before table

Recieving messages

Need some process to receive messages from queue

Prepare dataset with proper Before/After information

Call saveChanges in beCustomer.p

Alternative approaches

Breaking up saveChanges

Create finer-grained services• createCustomer• deleteCutomer• changeCustomer• Could call saveChanges

Easier message handling Might need additional work for Datasets

Moving the services

Service “createCustomer”• Validation / processing• Create record in database

• Send Integration message

• Send email to salesrep• Send welcome package to customer

Moving the services

Business Task “createCustomer”• Validate and create record in database• Send Integration message• Send email to salesrep• Send welcome package to customer

Business Entity “customer”• “createCustomer”• Validate• Create record in database

Exposing the Business task as a service

Expose as Web service• ProxyGen

Use OpenEdge Adapter for Sonic ESB®

In Summary

SonicMQ and the Reference Architecture

• Need to bridge XML messages and ProDatasets

• Can reuse existing Business Servicing Layer

• Well defined services are easier to integrate
