Our human civilization rests on the power of abstraction, insofar as the volume of specific cases handled by an abstraction is typically much greater than the overhead of the abstraction mechanism itself.  Charles Simonyi

In part 1 of raising the level of abstraction, I discussed a computer-assisted business process management tool that provided Business Analysts the capability, through a modeling tool, to completely define an application integration solution.  This modeling tool sits on top of Microsofts BizTalk Server integration server product. 

 

The modeling tool is actually a Domain Specific Language (DSL) which is used to configure a software factory schema for a particular application integration scenario.  This software factory schema is then used as input to a software factory template, which configures MSFTs Visual Studio IDE to automatically generate (with minimal coding) and build the application integration solution.  This raising the level of abstraction increases programmer productivity through systematic reuse of pre-built components and for the customer, increases product time to market, increases product quality, and introduces predictability and repeatability to an otherwise CHAOS process.  I call this software industrialization.

 

Whats my point?  DSLs are a key enabler
