Ok i have a database, thats resides on a server... different ppl need to access it and update it... but obviously not overwrite the dbase, what is the best way to do this without big development around it?

This is a pretty open question. Here's a few things that we'd need to know before offering advice...

1. What type of database is it? Access, MySQL, SQL Server, Oracle, etc?
2. What type of server are you running on? Linux, Windows, etc?
3. What level or programming experience do you have?

With those questions answered, we can give you a more definate idea of where to start.
