i'm developing a framework (mod_perl+apache) that reads the db-schema and 
explode html forms.

now i read the schema and cache it into perl-hashes to speedup things.

my problem is to recognise when a table is altered so that the framework can 
update the related forms connected to the db tables.
i don't want to read the schema every time.

How can i implement this ?


thank you in advance for your help
