Overview of WebSphere Adapter for PeopleSoft Enterprise

WebSphere® Adapter for PeopleSoft Enterprise provides you with a way to create integrated processes that include the exchange of information with a PeopleSoft Enterprise server. Using the adapter, a client application can send requests to the PeopleSoft Enterprise server (for example, to query an employee record in an HR table) or receive events from the server (for example, to be notified that an employee record has been updated). The adapter creates a standard interface to the applications and data on the PeopleSoft Enterprise server, so that the client application does not have to understand the lower-level details (the implementation of the application or the data structures) on the PeopleSoft Enterprise server.

WebSphere Adapter for PeopleSoft Enterprise complies with the Java Connector Architecture (JCA), which standardizes the way application components, application servers, and enterprise information systems, such as a PeopleSoft Enterprise server, interact with each other.

The adapter component, which you generate with the Adapter Connection wizard, uses a standard interface and standard data objects. The adapter component takes the standard data object sent by the client application and calls the PeopleSoft function. It then returns a standard data object to the client application. The client application does not have to deal directly with the PeopleSoft function; it is the adapter component that calls the function and returns the results.

For example, the client application that needed the list of employees would send a standard business object with the range of skill codes to the PeopleSoft adapter component. The client application would receive, in return, the results (the list of employees) in the form of a standard business object. The client application would have no need to know how the function worked or how the data was structured. The adapter component would perform all the interactions with the actual PeopleSoft function.

Similarly, the client application might want to know about a change to the data on the PeopleSoft Enterprise server (for example, a change to the skills set of a particular employee). You can generate an adapter component that listens for such events on the PeopleSoft Enterprise server and notifies client applications with the update. In this case, the interaction begins at the PeopleSoft Enterprise server.
