If you have the skills in-house to manage it, then you want a proper RDBMS.
Something like PostgreSQL is available for free and would be appropriate for a medium-size application with a reasonable number of concurrent users. You'll need to write/modify your applications to use a RDBMS.
If you don't have the skills then I suggest using something like Google Docs. It's not as sophisticated, but it does work well with a lot of concurrent users (certainly better than emailing Excel spreadsheets around).
