Healthcare Service Scenario

Healthcare Service Scenario - Demo

WSO2 ESB – In a nutshell..

• Message and Service Mediation Managing and transforming messages Mediating messages coming into a specific proxy service

hosted on ESB • Mediators

Simplest functional component. Performs a predefined action on a given message

• Sequences Sequential arrangement of mediators

• Proxy Services Hosting proxy services inside ESB Protocol switching and QoS

• Endpoints A logical representation of an actual endpoint, or else a

collection of endpoints wrapped within some logic.

Templates

• With complex business requirements, ESB config can grow bigger..

• Need a way to reuse the configuration

• WSO2 ESB 4.0 introduces – Templates

• An analogy… classes vs instances

Enhancing Healthcare Scenario with Templates

• Splitter : Iterate through the message and sending a portion based on the config.

• Using ‘iterate_function’ template to reuse the sequence logic.

• Required parameters for iteration is passed when calling the template. (i.e. calltemplate mediator)
