Extending UML to Support Domain Engineering






reuse


This work describes a domain engineering 
approach and the supporting tools to define 
software product lines. The approach is composed 
of a process and a notation. The 
notation is an extension of UML (Unified 
Modeling Language), the process is influenced by 
Synthesis [SPC93] and FAST [Weiss99]. Supporting tools 
have been built on top of a 
commercial CASE tool for UML. The approach 
is being applied to sub-domains of the 
Guidance Navigation and Control domain, a set 
of functionalities used on board of satellites 
developed by NASA Goddard Space Flight Center.
