Where can I get ready-made REST and SOAP services?

Question

SOAP

I'm trying to learn web services, to start practicing, you need to install one of them, but I did not understand how to do it. In Russian, I did not find anything sensible on the Internet.
That is, the database with the data already exists, you need to install a service that will be an intermediary when working with this data.
The programming language is not important.
Suggest a book or site with installation guidance (REST and SOAP) locally.
Or describe how generally usually put services?

Answer 1

They are not installed, but programmed. Easy to google for any language like "LANGUAGE_NAME REST API tutorial"
