State the data flow diagram of functional model
Any action initiated by transition in the state diagram can be extended into an entire data flow diagram in functional model. The methods in a data flow diagram comprise of sub-operations that may be operational on original target object or on the other objects. We can determine target object of a sub-operation as below:
i) If process extracts a value from I/P flow=> input, flow is target.
ii) If process has same type of input and output flow and output value is the updated version of I/P => I/O, flow is the target.
iii) If process has an I/P from data source or an O/P to a data source => data, source is a target of process.
iv) If process constructs O/P value from several inputs => operation is class operation on output class.
