A context diagram is a top-down visual representation of the system, which helps to understand the environment and gives an overview of how it interacts with external entities. It is used to depict the data flow between certain external actors, processes, and systems in regard to an online ticket booking application. The diagram outlines major processes in order for one to purchase tickets, such as a “Customer” who books a ticket for a particular event, an “Entity” such as a show or theater where the ticket needs to be booked, and a “Payment Processor” for money transactions involved.
