About Using Collections
Collections enable you to temporarily capture one or more nonscalar values. You can use collections to store rows and columns currently in session state so they can be accessed, manipulated, or processed during a user's specific session.
Managing Web Source Modules
Web Source Modules act as a reference to one or multiple external web services. A module can contain one or many Web Source Operations which are the references to a concrete external web service.
Managing Remote Servers
A Remote Server is separate entity that stores Web Source server information. Remote Servers can be shared among multiple Web Sources, thus enabling you to information such as the Base URL or Authentication.
