Differentiate between structural models and behavioral models.

  The difference between structural models and behavioral models are:- 

Structural Models

  • Structural models of software display the organization of a system in terms of the components and their relationships.
  • Structural models may be static models, which show the structure of the system design, or dynamic models, which show the organization of the system when it is executed.
  • Structural models are created when discussing and designing the system architecture.


Behavioral Models

  • Behavioral models are models of the dynamic behavior of a system as it is executing. They show what happens or what is supposed to happen when a system responds to a stimulus from its environment.
  • You can think of these stimuli as being of two types:

•A. Data Some data arrives that has to be processed by the system.

•B. Events Some event happens that triggers system processing. Events may have associated data, although this is not always the case.

  • A sequence diagram and State Transition Diagram may be used for the behavioral model.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?
