php, windows server 2008, iis7, fastcgi
use a textfile as a database
is this what caching is
would this be a php odbc connection
my sql server 2005 database is getting very large (which is slowing load time for my important data), so I would like to use a textfile for my data that is not important
why is it not recommended to use a textfile as a database does it use alot of cpu or ram
