Component Model – Concepts 
The component model consists of the following elements:
· Development objects are created in the context of development components; they are stored as versioned files in the Design Time Repository.
· Development components(DCs) are development and build units; they group development objects without overlapping.
· Software components (SCs) are delivery and installation units; they group development components without overlapping.
· Products are overlapping selections of software components. One software component can be part of several products.
