For example, the time to develop the application using DSM is a
fraction of the time to create the UML diagrams and write the code manually. DSM
also prevents errors early on since the language does not allow illegal designs or
14 INTRODUCTION
designs that don??™t follow the underlying architectural rules. The code produced is
also free of most kinds of careless mistakes, syntax, and logic errors since a more
experienced developer has speci?¬?ed the code generator. We inspect the effect of
DSM development on productivity, product quality, and required developer expertise
in more detail in the next chapter.
One example obviously cannot cover the wide spectrum of possible development
situations and application domains. The mobile example is one of thousands, if not
hundreds of thousands, of different application domains. In principle, different
DSM solutions can be used in all of them since every development project needs to
?¬?nd a solution in the problem domain and map it into an implementation in the
solution domain. All development projects have faced the same challenge. In Part
III of this book, we inspect different cases of DSM and aim to cover a wider range
of problem domains generating different kinds of code, from Assembler to 3GL and
object-oriented to scripting languages and XML.
The bene?¬?ts of DSM are readily available when the DSM solution??”the language
and generator??”is available.
