Here is the application task i was given....first here is some information, the business is called Wrecking Builders the owner is Washington Paul it is a building and measuring business... heres the process of how they get their sales and jobs...
"When a request for a quote is received (usually by email), the client is contacted and an appointment time is made, Washington visits the client, measures the building site and then gives these measurements to Moki(his office manager) on a piece of paper to prepare the quote. Once the quote is prepared, Moki prints it out for Washington to aprove or edit. Washington either signs the quote 'approved' or makes edits using a red pen and then hands it back to Moki. She then makes the required changes, prints the quote out again and sends it out to the client

What is the relationship between a context diagram and diagram 0?
A context diagram shows the system as a single process with interactions between it and external entities, while a diagram 0 (also called a level 0 data flow diagram) expands on the context diagram by breaking down the system into more detailed processes and data flows within the system itself. The context diagram provides an overview, while the diagram 0 provides a more detailed look at how the system functions internally.

Thus we have knowledge what Diagram Zero DFD contains, which is the same entities and same data flow but only the processes will break down into the lower sub process.
Why does a context diagram not show data stores?
A context diagram focuses on showing interactions between a system and external entities, such as users or other systems, without detailing the internal workings. Data stores are considered internal to the system, so they are not shown in a context diagram to keep the diagram simple and to maintain a high-level view of the system's boundaries and connections.
