Analysis Modelling
Since many important contributions to software engineering structured analysis was not introduced with a single landmark book or paper which was a definitive treatment of the topic. In the earlier work in analysis modeling was begun in the late year 1960s and early 1970s but the 1st appearance of the structured analysis approach was as an adjunct to another important topic-structured design, Research hers required a graphical notation for representing data and the processes that transformed it. This procedure would ultimately be mapped into design architecture.
The term structured analysis really coined through Douglas Ross, was popularized through DeMarco [DEM79]. The subject, DeMarco named and introduced the key graphical symbols which enabled an analyst to build information flow models suggested heuristics for the use of these symbols suggested in which a processing and data dictionary narratives could be used as a supplement to the information flow models and presented numerous examples which describe the use of this new technology. In the years that followed, variations of the structured analysis approach were suggested through Page-Jones [PAG80] Sarson and Gane [GAN82] and several others. In each instance the technique focused on information systems applications and did not give an adequate notation to address the behavioural and control aspects of real-time engineering problems.
By the middle 1980 the deficiencies of structured analysis when attempts were made to apply the technique to control-oriented application became painfully apparent. Real-time extension was introduced through Mellor and Ward [WAR 85] and later through Pirbhai and Hatley [HAT87] these extension resulted in a more robust analysis technology which could be applied efficiently to engineering problems. Attempts to establish one consistent notation have been [BRU88] modernized treatments and suggested have been published to accommodate the use of CASE tools [YOU89].
