I came across this jewel while searching on IIS 7 Extensions. Basically it extends IIS Manager by allowing users to manage SQL Server or MySQL databases!
A logical question comes to mind. SQL Server Management Studio is available and provides lot more features then what is the need for this extension?
This extension is particularly helpful in case of remote administration of databases. With SSMS, certain firewall ports need to be opened which may or may not be possible in certain environments. Since IIS Database Manager runs on the IIS Server, hence the server administrators can delegate database management to authorized users without opening additional ports for DB management.
