g., Weiss and Lai, 1999) is to
focus on specifying just variation: how products are different. The commonalities
are then provided by the underlying framework. For companies making applications
on top of a platform, DSM works well as it allows having languages that hide the
details of the libraries and APIs by raising the level of abstraction on which the
applications are built. Application developers can model the applications using
these high level concepts and generate working code that takes the best advantage of
the platform and its services. DSM is also suitable for situations where domain
experts, who often can be nonprogrammers, can make complete speci?¬?cations using
their own terminology and run generators to produce the application code. This
capability to support domain experts??™ concepts makes DSM applicable for end-user
programming too.
1.6 SUMMARY
Domain-Speci?¬?c Modeling fundamentally raises the level of abstraction while at
the same time narrowing down the design space, often to a single range of products
for a single company. With a DSM language, the problem is solved only once by
visually modeling the solution using only familiar domain concepts. The ?¬?nal
products are then automatically generated from these high-level speci?¬?cations with
domain-speci?¬?c code generators.
