Modeling the activities of an application domain is a necessary extension of modeling the structure and behavior of objects in the domain. Object models capture the structure and behavior of components in the application domains, whereas activity models are used to describe the functionality of the domain. The integration of object and activity modeling is essential for producing complete domain models in which the objects and activities are mutually consistent. Realization of such domain models simplifies the development of sophisticated applications. Using a DBMS simplifies the realization of the model and further facilitates the development of multiuser applications.

The notion of Process is introduced as a modeling construct for activities. Process decomposition and Process hierarchies are introduced as mechanisms that allow abstractions of activities. The notion of Signal is introduced as a mechanism for Processes to communicate and exchange data. Language facilities for defining Process and Signal are presented.
