Difference between activity diagram and dfd?
In data flow diagrams, the lines between "boxes" represent data that flows between components of a system. Because these only show the flow of data, they do not give an indication of sequencing.In activity diagrams, those lines are simply transitions between activities and do not represent data flow at all. They more represent the sequencing of activities and decisions. You can tell from these what order things happen in.
Difference between dataflow diagram and sequence diagram?
The purpose of a data flow diagram is to show you how the data flows through an information system. A sequence diagram shows you information regarding how the processes work together and in what order they operate.
Difference between Data flow diagram and control flow diagram?
A data flow diagram illustrates how data flows from logical point to point in a system. Examples of nodes in such a diagram are databases, tables, discs, servers, clients, etc.. A control flow diagram illustrates how different programs, applications, services, or endpoints act on and process information to achieve certain ends within the context of a system.
Difference between dfd and er diagram?
actually dfd is used to define how data flow from one process to another process where as er diagram is used to define relation between different entities.
What is difference between block flow diagram and process flow diagram?
BFDs provide a complete overview of the whole process in block diagram form. They summarise the major unit operation between process block units. PFDs characterize all the process flows to and from all the equipment required to perform the process within the boundaries set by the BFD
