In this paper, the authors present a generative approach to build a Software Product Line (SPL). This Software Product Line (SPL) is used to build applications based on the notification of changes in databases. The paper highlights the benefits, in terms of productivity and cost, using this approach. To obtain the economic data they have used two cost models, the Structured Intuitive Model for Product Line Economics model (SIMPLE) and one adaptation of COnstructive Product Line Investment MOdel (COPLIMO). Both models demonstrate the great productivity of this SPL. The paper also introduces the Exemplar Driven Development (EDD) process used to build the Software Product Line (SPL).
