What is data flow oriented design?

Data flow oriented design represents the flows of data between different processes and data structured design is considering about what information we should input and take as the output. Data flow oriented-design approach is the one of the first comprehensive and well documented design method.

What is the basic difference between a control flow oriented and a data flow oriented design technique?

The major difference between control flow and data flow in SSIS is that Control Flow can execute only one task at a time in a linear fashion. On the other hand, Data Flow can perform multiple transformations at the same time.

What are the techniques of function oriented design?

Function Oriented design is a method to software design where the model is decomposed into a set of interacting units or modules where each unit or module has a clearly defined function. Thus, the system is designed from a functional viewpoint.

What is data flow diagram how are they different from structure chart?

Flow chart is a convenient technique to represent the flow of control in a program. Structure chart represents the software architecture. Flow chart represents the flow of control in program. It is easy to identify the different modules of the software from structure chart.

What is difference between data flow analysis and control flow analysis?

Data-flow analysis is a technique for gathering information about the possible set of values calculated at various points in a computer program. A program’s control-flow graph (CFG) is used to determine those parts of a program to which a particular value assigned to a variable might propagate.

Which tool is used for structured designing?

Structure Chart
Which tool is use for structured designing? Explanation: A Structure Chart (SC) in software engineering and organizational theory, is a chart which shows the breakdown of a system to its lowest manageable levels.

What is function oriented and object oriented design?

Object oriented design is the result of focusing attention not on the function performed by the program, but instead on the data that are to be manipulated by the program. Thus, it is orthogonal to function -oriented design. Object-oriented design begins with an examination of the real world “things”.

What are the three major data flow approaches?

Approaches for Data Flow Diagrams (DFDs): (a) DFD representations; (b) Explosion approach to DFD development; and (c) Expansion approach to DFD development.

What are the four major components of a DFD?

All data flow diagrams include four main elements: entity, process, data store and data flow. External Entity – Also known as actors, sources or sinks, and terminators, external entities produce and consume data that flows between the entity and the system being diagrammed.
