Online Shopping System Context Diagram
A context diagram is drawn in order to define and clarify the boundaries of the software system. The online shopping system context diagram, sometimes called a level 0 data-flow diagram, identifies the flows of information between the system and external entities. Here the external entities are the customers who visit the online shopping site to either search for books and place orders. The system module is where the administrator will update the website and provide relevant information to the accounts team. The system-level 0 data-flow has elaborated the high-level process of banking. The system context diagram shows how customers and administrators process information at the online shopping system. Also, the level 0 data-flow diagram shows how third parties initiate the money transfer to the bank system.
