Well, if its numeric checking, you can do that mathematically. If it is
string checking, yes, you will have to push it across a network. If you are
using a Web UI there are ways of compressing the data on the fly with gzip
extensions to Apache & PHP. This usually compresses normal text data 10:1.
This will help but you still need to pull all this data out of a database so
it would have to be used properly. If you wrote a bunch of javascript
functions that did various kinds of checks, it would be very easy to include
them in your output & use them as necessary.

I assume we are talking about a local network, this will also give you a
little more room to work when it comes to bandwidth, if you're working over
the internet, possibly over a slow connection, you would have to keep the
data transfer to a minimum.
