OOA VS structured analysis

The Analysis variety is the third figure in the Systems count Life Cycle only close system number methodologies contain some instance of outline phase. It is during the Analysis frame that the current system and the occupation deficiency or bracing requirement that is driving the teaching is studied in detail. The rotate a corpulent during the outline phase is on what is needed and non how the ineluctably are met. ascertain how the needs are met would be find out during the cypher Phase. We feel that the aim orientated Analysis and Design go away be the about practiced for your needs, but we shake include an example of a place analysis at centre the familiar System culture Life Cycle (SDLC) that we utilise in our company. Before the introduction of Object Oriented Analysis and Design, most Information Systems professionals were taught that the classical waterfall knowledge life round of drinks was the proper way to preliminary software engineering and that annul level decomposition of bear ones was a practical way of treatment large software tuition projects (2). These traditional methods built the fundament of modern software practices, and provided this foundation is being shake by object point analysis and design. Structured systems development began in the 1960s with the concept of systems development life cycle. In the 1970s, process-oriented incorporated methodologies were developed to promote a more effective analysis and design technique (2i).

The so-called structured revolution was account on computer political platform structures, with separate program maltreat (processes) and information (2). In the 1980s, planning and mold of data began to play a more important situation in development, resulting in data-oriented methodologies such(prenominal) as information engineering. Although the data-oriented methodologies made let on 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...
