Sorry if someone has already asked this, but what is the difference between Data Flow Diagrams and Context Diagrams?

Context diagrams:
* method of representing a system using ONLY a single process, with inputs and outputs.

Data flow diagrams:
* method of representing a system using A NUMBER of processes with inputs, outputs, and storage.

:)

Differences:
Context - single process, input and output.
DFD - multiple processes, input, output and storage.

hmmmmm
my definition!

Context Diagrams:
- method of representing a single process in an information system. (similar to Huy)

Date Flow Diagrams:
- method of representing the flow of data/information in an information system, from process to process in the system. A DFD forces more on the flow of data in a system (different in some ways)
