Portlet Factory, Version 6.1.2
Using data services
IBM® WebSphere Portlet Factory provides the services category of builders that you can use to create, test, use, and document data services.
The services builders rely on various data integration builders (for example, SQL Call, SAP Function Call, and Domino Data Access) to access data from a backend database.
Parent topic: Overview: working with data services
- Adding custom input or result processing to an operation
To perform additional manipulation or validation of data, you can call Java code during operation execution.
- Usage of a Service Mapping Registry File
One of the greatest benefits of using a Service Oriented Architecture (SOA) approach to building data-driven applications is that the data services code and the application using the data are completely separate.
- Registry mapping file mappings
The definitions of the mappings are fairly easy to understand.
- Redirecting service provider references
Essentially, a Service Mapping Registry file works by identifying conditions under which a Service Provider reference need to be replaced by or swapped with another Service Provider reference and providing the model ID of the replacement Service Provider.
- Registry mapping file selectors
Selectors evaluate to either true or false. If the conditions exist that make a selector's criteria evaluate to true, then the mapping declared inside the selector is used.
- Transforming data returned by a service
You can transform operation inputs and results into a different schema structure using this Service Operation builder.
- Using an action list, method, or LJO method in an operation
Follow these steps to use an action list, method, or LJO method in an operation.
- Building a service-oriented application
Building a service-oriented application involves creating a service provider model and a service consumer model.
- Creating an operation based on an integration builder
These steps describe how to create an operation based on an integration builder.
- Data service documentation
Follow these steps to display information on the selected services, their operations and parameters.
