...data modeling and normalization. This chapter shows a process of providing full specification of systems to users to help them consider and accept. This specification is also a major information source for designers of the new system. It not only specifies the system's objectives but also describes the work and its constraints to which designers have to comply.
2.1 Analysis of structured system
This part discusses the process of system analysis, analysis methods and tools supporting the analysis of data collected in previous surveys.
2.1.1 Overview of system analysis
System analysis is a relatively young field in mankind's knowledge but demand for system analysis existed many centuries before the introduction of computers. In mid 19 century, practitioners in labor, organization and methodology had established many improved methods of working. This is the first approach to system analysis.
With the development of information technology, system analysis science also develops more and more vigorously and has a significant role in a life cycle of an IT application and of IT projects in general. At the moment, there is no method that ensures success and that can be viewed as a "right" way for analysis but the application of structured system analysis increases the chance of success for most of typical applications and it proves efficient in a range of analysis in real life.
Until today, system approach is still viewed as a sound foundation for structured system analysis.
Structural system analysis is a modern approach to different analysis and design phrases of the system development process which is accepted because of its strong points over other traditional approaches. The structural system analysis has the following main characteristics:
The system is developed in the top - down order;
During system analysis and design, several tools, techniques...
