Some can be done on the client without hitting the server. If, for example, I decide my invoice numbers follow this patterm, "XXX-9999" then I could customise the JS to verify that it follows that pattern. If my part numbers somehow encode the class of product then it could very the "unit" column is valid, so I don't have five days of disk drives. When I learned my computing back in the 70s, we learned to check data items for correct characters so that numeric fields contain valid numbers, pensioner numbers are valid pensioner numbers (within range, correct check digit) and so on, and that individual transactions were internally consistent. Records that pass those checks are then validated against data files. We could have a valid pensioner number, but no pensioner with that number, and that's the kind of error this validation would catch. A standard check that _could_ be included is that an email is syntactically valid. Other checks might be added as customisations by us, the users. -- Cheers John Summerfield Microsoft's most solid OS: http://www.geocities.com/rcwoolley/ ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ------------------------------------------------------- (un)subscribe: http://lists.sourceforge.net/lists/listinfo/sql-ledger-users Archive: http://www.mail-archive.com/[email protected]/
