What is the difference between a context diagram and diagram 0
It says that a context diagram is the same as a Level 0 DFD. This one disagrees on page 210. I'll first address the notion of "levels". As we know, initially, the whole of the system is represented by one big block, and interactions with the system are clearly depicted. Initially, we are seeing the system with a naked eye.
A context diagram is a top level view of a system that displays the boundaries and scope of the system. Diagram 0 is a DFD that shows the first level of detail below the initial context diagram and shows major processes, data flows and data stores while repeating the external entities and data flows that show up in the context diagram.

The system context diagram (also known as a level 0 DFD) is the highest level in a data flow diagram and contains only one process, representing the entire system, which establishes the context and boundaries of the system to be modeled. It identifies the flows of information between the system and external entities (i.e. actors).
Which symbol is not used in a context diagram? The context diagram provides different views of information system. Diagram 0 is used to provide insight view of an info system represents internal process, entities, data flow, and data storage. Data stores are not used in a context diagram. How would you explode DFDs?
The diagram 0 is used for providing deep insight view of a system and represents the major internal process, data flows and data stores. The relationship between context diagram and diagram 0 is that diagram 0 is the detailed description of the context diagram. When context diagram is expanded into diagram 0 then all the data flow must be retain.
A context diagram shows the top level view of an Information System (IS) that depicts its boundaries and scopes. A Data Flow Diagram (DFD) specifies the way system would store, process and transform data into information. The increasing levels in these diagrams increase the details of the IS.
