Lei Li · Dianzi xuebao · 2012
How to unambiguously represent the relationship between data items and then extract the deeper level relationship between them is playing an important role in requirement engineering,but good methods for it doesn′t exist in current requirement analysis methods.At present there also doesn′t have method or thoughts for how to extract the data and data item of software system from data of requirement by deduce.In this paper,we use the method of Data Floating Direction Chart(DFDC) to extract the necessary data and data item for software systems and to represent the relationship between data items.The DFDC can make representation of relationship between data items more clearly and extraction process of data items more easily.
