That all really depends on you. I would certainly say that, in general, any given database should only have one users table (with a separate table holding roles, permissions, etc.) In all likelihood - if all of these systems will be working together within a single company, and be built in a common way - you'll likely find it easier to have them all in one system.
The counter to that, of course, is that information like payroll certainly shouldn't be easily accessed - so that might be one case where you might want a separate database. You'll really just have to weigh the benefits of having the data together (generally convenience, though there are reasons along the lines of joins and such) with the costs of any lost security or lax in responsibility. - Martin Norland, Database / Web Developer, International Outreach x3257 The opinion(s) contained within this email do not necessarily represent those of St. Jude Children's Research Hospital. -----Original Message----- From: Perry, Matthew (Fire Marshal's Office) [mailto:[EMAIL PROTECTED] Sent: Monday, October 18, 2004 2:38 PM To: [EMAIL PROTECTED] Subject: [PHP-DB] how many databases should I create I am developing a variety of different web based systems including inventory, payroll, incident reports etc. Should I create a new database for each project category or one huge database with every table I will ever use in it? -Matt -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
