2.5. Domain specific languages

A programming tool that is appealing to less qualified developers, may also be appealing to experts on areas that are important for a software product.
For instance:

An economist could define business rules to be implemented by a software product.
A translator could localize a software product.

These experts could participate directly in the development of a software product, especially if they do not have to learn traditional programming languages.
Domain specific languages could be used by these professionals.
