Web 2.0 is a fine thing. You can build whole websites, news systems, or picture galleries – just by using the power of content submitted by users.

But be careful! You can never trust every user when it comes to submitting data. There are always those who may try to compromise your website by submitting bad queries. Even if unintentional, it can be possible for users to destroy your database’s consistency just by entering incorrect data.
