Assignment Help:

From SAD to OOAD (Structured Analysis and Design (SAD) to Object Oriented Analysis and Design (OOAD).

We will find here how we can map various models in SAD to different models in OOAD. We will consider different levels of abstraction through which this is done.

The data flow diagram (DFD) of SAD is mapped to Use Case diagram of OOAD.

DFD represents a broader model of the system from process point of view. Hence, DFD could not be transformed as it is to equivalent representation in UML
