its cool and easy tutorial
While installing the Magento we have the option to use a database prefix for our Magento tables in the database.
Using such a database prefix adds to the security of our site, because generic SQL Injection attacks and more likely to fail.
But if you installed Magento by using the demo-data or if you forgot about this thing during installation, stuck with a database without the prefix.
