Detailed explanation-1: -Process-Activities and action taken on the data are represented by Circle or Round-edged rectangles.
Detailed explanation-2: -Data flow diagrams represent systems by use of a sparse number of symbols. Systems processes are symbolized by circles, entities external to the system which interact with the system are represented by rectangles, and data stores are denoted by an open ended rectangle.
Detailed explanation-3: -Process is activities & action taken on data represented by Circle or Round-edged Rectangles.
Detailed explanation-4: -A process is represented by a circle in basic Data Flow notation.
Detailed explanation-5: -There are two distinct types of data flow diagrams: the logical DFD and the physical DFD.
Detailed explanation-6: -The process model is a core diagram in structured analysis and design. Also called a data flow diagram (DFD), it shows the flow of information through a system. Each process transforms inputs into outputs. Flow lines represent data flowing between nodes including processes, external entities and data stores.
