As you pose your question there is a lot of information to give you. To put it simply, a web service is a program that you put on a server and that is available through the internet.
As you said that you have a sql server I understand that you have it in a windows server, if so, what you have to do is activate IIS, mount the web service and find out the route.
Once done, the application connects with that service and receives the information.
Investigate about that and if you have more concrete doubts open new topics.
