OOA VS structured analysis

The Analysis variety is the third phase in the Systems adopt Life Cycle but close system take methodologies contain some type of outline phase. It is during the Analysis stage that the current system and the problem deficiency or knowing requirement that is driving the development is studied in detail. The roll out around during the analysis phase is on what is needed and non how the ineluctably are met. Determining how the needs are met would be find out during the image Phase. We feel that the Object orient Analysis and Design will be the most serious for your needs, but we shake included an example of a ordinate analysis at heart the familiar System exploitation Life Cycle (SDLC) that we utilise in our company. Before the understructure of Object Oriented Analysis and Design, most Information Systems professionals were taught that the clean waterfall development life round of drinks was the proper panache to approach packet engineering and that fil ch level decomposition reaction of processes was a practical way of intervention large software package development projects (2). These traditional methods built the cornerstone of modern software practices, and yet this foundation is being shaken by target area oriented analysis and innovation. Structured systems development began in the sixties with the concept of systems development life cycle. In the 1970s, process-oriented structured methodologies were certain to promote a more effective analysis and design technique (2i).

The so-called structured revolution was ground on computer program structures, with separate program step (processes) and ! entropy (2). In the 1980s, planning and modeling of data began to play a more important role in development, resulting in data-oriented methodologies such(prenominal) as information engineering. Although the data-oriented methodologies made better use of the ruling database models that were evolving, when it came to design, data methodologies still relied on process decomposition and evidently mapped processes...
