model of functionality, relevant functional attributes of software are identied.
eir extent and limits are dened, and their generic interactions are described.
Taken as a whole, these functional attributes form a generic model for any type of
software that is not algorithm rich. e model is illustrated in Figure1.4.
Four types of data movement are dened within this model. ey form the
basis for dening the standard unit of functional size. e four types of data move-
ment are presented in Table1.1.
