                    Notes          Context Models

                                   Context models are used to illustrate the boundaries of a system.
                                   Social and organisational concerns may affect the decision on where to position system boundaries
                                   Architectural models show the a system and its relationship with other systems

                                                          Figure 9.2: Context of an ATM System

                                   Process models show the overall process and the processes that are supported by the system
                                   Data flow models may be used to show the processes and the flow of information from one
                                   process to another
