[scott miles]

Me and my friends are cplanning bto construct a website for some company which it will be using for its commercial purpose.
My question here can we use miscrosoft sql server free edition for commercial purpose?

Apart from that miscrosoft sql server provides free edition and commercial edition both. What are the important features any company provide
in its commericial edition which it does not provide in free edition?
