IBM Digital Data Connector (DDC) for WebSphere Portal

Use the IBM Digital Data Connector (DDC) to integrate data from external data sources to portal pages using WCM presentation components. For example, use DDC to render social data located on an IBM Connections server. Other data sources could include news feeds, task lists, product catalog information.

We use WCM presentation components to generate the web page markup for the external data. Facilities include syndication, versioning, workflow, and targeting. Design components are managed in the same way as the other WCM content and design components. We can use the inline editing capabilities of WCM to modify presentation templates. We can hold updates of WCM components until all updates to the project are completed, approved, and published.

We code DDC plug-ins that load and transform external data into DDC bean lists, which are rendered on the portal pages using standard WCM rendering methods.

Alternatively, to integrate remote XML data without writing or deploying extra Java code, use the built-in XML DDC plug-in, which supports parameters for specifying where the plug-in obtains the XML data, and how it transforms the data.

We can also use a combination of the two approaches.
