Among the plethora of features to support portlet developers using WebSphere Portlet Factory is the Schema builder. The value of this tool is not trivial.

One of the best examples of its value is in the construction of result set schemas. By providing a single SQL Call builder with multiple Service Operation builders  developers are able to deliver multiple column contents from a single data service integrator. Suppose you wanted, for example, to have a display of records with "all twelve" columns and another display with "only four"? By using multiple custom schemas and mapping each to a unique Service Operation builder you can use a single data retrieval builder, such as the SQL Call builder, for varied output.

Check it out, it is cool.
