A programmer that doesn't document stuff needs to find a new job :-)
This is more of an issue with management.  Anyone who does database apps
for on any kind of a large scale will tell you that views, triggers, etc..
are essential.  I am currently in teh process of writing a complete solution
for the college I develop for.  Finance, accounting, pos, registration,
student tracking etc...

You might not have understood me or I am not understanding you.  Changing
languages is not teh problem, if the database doesn't support views it still
won't if you change languages lol!  Changing databases in this case is the
answer.

Swig is awful.

Much of the populatity of MySQL seems to stem from PHPs out-of-the-box
support for it. With the MySQL client library license change, this
situation will probably change. There was a long thread about this earlier
this year. Check the archives.
