Active object

Active object is a term that denotes the object, or set of objects, in a data source, that are selected in the user interface at a given time. The concept is used in conditions and data filters to let the app react to selections the user makes.

For example, in a form with one list of customers, and one list of customer contacts, the list of customer contacts can be filtered on the selected customer or customers.
