A system and method are presented that integrate date-related data from a variety of disparately defined data sources into a single user interface. Date-related data is defined in tactics that are associated with types. The types are associated with additional field definitions that allow for a single tactic data entity to be created for a variety of tactic types, with different tactic types being associated with different sets of additional fields. Cues are also used to automate the generation of date-related tactics. Cues can be triggered by the creation of trigger tactics of a predetermined type, or through an event in a subscribed database. Individual tactics record estimated and actual expenses for budgeting purposes. Finally, plan hierarchies allow for the integrated viewing of date-based tactics defined at different levels of the hierarchy.
