Microsoft Office SharePoint Designer 2007 is a new product
that is included with Microsoft Office 2007. It allows you to create and
customize Microsoft SharePoint Web Sites. It also does allow in building
Workflow enabled applications based on Sharepoint Technology. Because of its
tight integration with SharePoint we need to use this for building our Master
Pages. Actually, you can even use Notepad to build Master Pages. However, you
need to be really good at HTML programming. SharePoint Designer 2007 provides a
visual interface to create this HTML formatted pages.
