Can someone give me a quick overview of what is required to pull Salesforce data into Sharepoint 2007 web parts? Specifically, we would like to pull a dashboard gauge, chart or table, or a report, into a Sharepoint web part that displays on a Sharepoint page.

Is there any software, library, toolkit or SDK required?

How is the call made to Salesforce? How is the authentication handled?

Thanks

Jay Brennan
