Unified approach for system-level generative programming

Today's and future distributed software systems will certainly require combining heterogeneous software components that are geographically dispersed so that its realization not only meets the functional requirements, but also satisfies the nonfunctional criteria such as the desired quality of services (QoS). The unified approach (UA) incorporates the concepts of product line practice (PLP) and generative programming with the unified meta-component model (UMM) to achieve automatic development, maximal reuse and seamless interoperation. The creation of a software solution for a distributed computing system (DCS), using the UA has two levels, the component level and the system level. In this paper, the system-level generative programming of the UA is described.
