I have developed a usercontrol that talk with webserivce that I made, in order
to deploy it into the Sharepoint site.

I have read many articles that talked about depolying webserivces into
sharepoint, but I still did not reached to the correct way.

Guys, if I developed a webservice method that return data from DB, and I have
added this webserivce to the usercontrol.
So what is the best practice to add a usercontrol with webservice into
sharepoint ?

I do not want to use the hard way, which creating a webservices with DLL and
depoly it to the GAC !
