A computer program product and apparatus are disclosed for managing task data. A task identifier that identifies a task is sent from a task processing portlet to a mapping engine, and then to a process server. A task type is identified by the process server based on the task identifier. The task type is sent from the process server to the mapping engine, which uses a mapping entry database that includes mapping entries to identify a set of queries and a set of data sources that are mapped to the task type. Data received from the set of data sources is aggregated in response to the set of queries to form aggregated data. The aggregated data is used by the human user to complete the selected task. The mapping entry is changed at runtime by changing the set of data sources that are mapped to the task type.
