ISBN : 978-81-963532-2-3 (E-Book) STRUCTUREDDESIGN The aim of structured design is to transform the results of the structured analysis (i.e. a DFDrepresentation)intoastructurechart.Structureddesignprovidestwostrategiestoguidetransforma tionof a DFDinto astructurechart. • Transformanalysis • Transactionanalysis Normally, one starts with the level 1 DFD, transforms it into module representation using eitherthe transform or the transaction analysis and then proceeds towards the lower-level DFDs. Ateach level of transformation, it is important to first determine whether the transform or thetransaction analysis is applicable to a particular DFD. These are discussed in the subsequent sub-sections. StructureChart 48 Software Engineering Keerthana P, Manasa KN, Ganga D Bengal
