In any context, the grasping power of diagram is multifold compared to text
The question is totally meaningless without context or a diagram. Don't come here to do your homework, study the book and do it yourself!
its a diagram
A diagram is a noun.
a Venn diagram consists of two overlapping circles, and is generally used as a compare and contrast diagram. a diagram in general is just a way to show information. in short, they are not the same thing, a venn diagram is a type of diagram.
context-free-diagramis a diagram that represents the actors outside a system that could interact with that system.
DFD diagram stands for Data flow diagram . DFD are also known as Context diagram.
The context diagram is very important part in FDD which stands for functional Decomposition Diagram. It will help us to create the baseline in context diagram which we will draw the entities and the main process. 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.
context diagram, logical level 0 diagram and logical level 1 diagrams
the system entities and how they are related
It means Friends With Benefits.
they are not different they are similar as level 0 DFD represents the primary individual process in system at highest level it is also called context diagram. It describes the overall system at highest level describing which element is inside and which element is outside the system..... youngheart_riwaj@yahoo.com
context diagram shows the system under construction as a single high-level process and then shows the relationship that the system has with other external entities (system, organizational groups, external data stores, etc.)
Context Diagram is higher level of abstraction of the whole system. It depicts the various subsystems that interact with each other along with major actors involved. It also gives you what information flows between the modules, actors and system at a high level.
I'm unable to view diagrams. Please provide a description or context of the diagram so I can assist you better.
In any context, the grasping power of diagram is multifold compared to text
1. Context diagrams are small and will fit on one page. 2. Use the name of the information system as the process name in the context diagram. 3. Use unique names within the other symbols. 4. Make the process named after the information system 0. 5. Identify all the entities. 6. Identify all the names and content of the data flow. 7. Identify the direction of the data flow. 8. Draw the diagram using appropriate symbols.
