The narrower the area of interest is, the easier it usually becomes to provide
effective languages and automation with generators.
Table 3.1 outlines 30 examples of areas in which the authors have been involved in
de?¬?ning DSM solutions. The problem domain is usually most visible in the modeling
language and the generator produces the code according to the solution domain.
Narrow Problem Domain For most developers, a narrow focus is set by
providing a language that operates on already known concepts relevant to the speci?¬?c
domain and has rules that guide developers in making the speci?¬?cations. For example,
a language can prevent incorrect or poor designs by simply making them impossible to
specify. This prevents errors early on??”when they are cheapest to correct. Such
guidance can be done during every modeling step by checking that models follow the
