Dear Allen,

I'm glad to hear about your project, and I'll take a look on that.

The first version of AppML (at the time called "auto_coder"), also 
worked directly on the SQL. The problem was that the database only 
provided a subset of the required semantics.

For instance: I was forced to use captions similar to the field names, 
and I wasn't able to tell if a field should be visible by default.

With XML, which is eXtensible, I can describe the project with as much 
information as needed.

Moreover, it's easier to parse a single XML source than the different 
SQL schemas out there.

The database creation scripts are generated automatically, and I use 
Class::DBI to achieve database independence and to make the resulting 
code more mantainable.
