Can I license SQL Web Edition for an ecommerce site or web site hosting?

Generally, you may use SQL Web for public facing, internet sites as long as the data available to 3rd parties is the same data available to your end users. You may not license SQL Web if the data is only intended for the end user’s employees or internal purposes. Thus, SQL Web may not be used to support your end user’s line of business applications (such as Microsoft Dynamics ERP solutions) nor any deployments that would make the end user’s data base available to the general public.
