Question

Difference b/w object oriented design function oriented design tabular

Answer 1

Function-oriented design relies on identifying functions which transform their inputs to create outputs. In most systems, functions share some global system state.

The functional design process involves identifying data transformations in the system, decomposing functions into a hierarchy of sub-functions, describing the operation and interface of each system entity and documenting the flow of control in the system.
Data-flow diagrams are a means of documenting end-to-end data flow through a system. They do not include control information. Structure charts are a way of representing the hierarchical organization of a system. Control may be documented using a program description language (PDL).
Data-flow diagrams can be implemented directly as a set of cooperating sequential processes. Each transform in the data-flow diagram is implemented as a separate process. Alternatively, they can be realized as a number of procedures in a sequential program.
