Chapter 10 What is Structure Analysis and Design Explain in Details
Introduction :- Hi everyone in this chapter learn details, What is SA (Structure Analysis ) and why is an important and where is use. Lets go start now.
Structure Analysis:- Structure Analysis is techniques that is uses graphical diagram to developed and property system specification that are easy to understand by the users.
Structure Analysis is a development method that allows the analysis to understand the systems and its activities in a logical way. It is a systematic approach, which users graphical tools that analyse and refine the objectives of an existing system and develop a new system specification which can be easily understand by the users.
The basic goal of SA/SD is to improve quality and reduce the risk of system failure.
Structure Analysis Tools :-
The tools and techniques used during structured analysis are
DFD (Data flow Diagram)
Data Dictionary
Structure English
Pseudocode
Design Tree
Design Table
DFD Structure Show in the Figure :-
Well next chapter discuss all point of DFD,
What is Structure Design?
Structure design is a concept of decomposing problems into several well-organisation elements of solutions. It gives better understanding of how the problems is being solved. Structure design also makes on the more problem accurately. Structured design is mostly based on divide and consider strategy, where a problem and each small problem is individually soled until the whole problem is solved.
The small pieces of problem are solved by means of solutions modules. Structures design emphasis that these modules be well organised I order to achieve precise solution.
