Interacting with SharePoint using WebService

In a typical developer guide, one will interact with SharePoint using SharePoint object model, i.e.  Using SharePoint libraries and then deploying code on SharePoint server.

However ever wondered what if one will not have execute permission on SharePoint server and still need to build a webpage which will be hosted on SharePoint and pulls data from libraries?

Here SharePoint Web services comes to rescue, SharePoint has their built-in Web service which allows users to access data without using SharePoint libraries. These Web service are usually found at http://<server-url>/_vti_bin/lists.asmx one can either add them as web reference or consume them using JavaScript Ajax

Below are some web services data which I managed to pull out.
