Q1) The requirements analysis phase answers the question, 'What does the user need and want from a new system?' The requirements analysis phase is critical to the success of any new information system. In this milestone we need to identify what information systems requirements need to be defined from the system users' perspectives.

The Data Flow Diagram (DFD) is a graphical representation of system which shows systems structure and components. The DFD shows how the data transforms in the system, what the source of the input is and what is the destination. Also, the DFD presents data structure and how it's stored.

In this milestone you will explode the Context level DFD to Level 0 DFD to show sub-systems (processes). The Level 0 DFD shows internal data stores and how data flows through the processes.
