On-Rev mySQL security issues? -- or use an LC stack for the DB?

Hi Kay,

Appreciate the input... I've wondered about mySQL's license, too.

Here is additional info. My catalog is an archive of the radio 
and TV programs we've aired. We will create the database and add 
to it bit by bit behind the scenes. No data will be input through 
the web/browser -- strictly look ups: Find all programs from year 
1999 that had Mr. Suzuki as a guest, and listen to them; that 
sort of thing. I've got a simple test working ok with mySQL, but 
no input validation yet.

Do I need input validation if the web interface is search only?

Also, I understand that the new LC server available on on-rev.com 
can serve stacks. Would it be less hassle/security risk to use a 
data stack, or even a big text file, as the database? We'll 
probably max out at 10,000 records or so... not breaking a sweat 
for a sql database. Manageable on a stack?  Need UTF8 (Japanese) 
which is working nicely with the web/mysql combo...

Any thoughts on validation needs for lookups only? And on using a 
stack or text file for the data? (Hmmm... how does the LC server 
handle variables - limit on size?)

Thanks!
