One of the new feature of SharePoint 2010 is the Client Object Model. By using Client Object Model, developers can build the applications which can talk to SharePoint without using WebServices and without deploying any server side code.

Following is the list of Client Object Model classes and their equivalent to Server Object Model classes:

{
  ClientContext clientContext = new ClientContext(siteUrl);
  Site siteCollection = clientContext.Site;
  Web site = clientContext.Web;
}
