Used to be portal server (up to 2003 version) and is now microsoft office sharepoint server -
MOSS
Adds the following over WSS:
- Sophisticated integration with office documents.
- Single sign on.
- 2-way synchronization of Outlook Calendar and SharePoint Calendar.
- Overlaying a SharePoint Calendar on top of user's Outlook 2007 Calendar.
- SharePoint Task-Assignment Synchronization into user's Outlook Task List.
- Offline Synchronization of SharePoint Documents.
- Viewing SharePoint RSS feeds through Microsoft Office Outlook
- Display of Meta-data values for a given document type in the Office Ribbon as a user is editing a document from a document library.
- People search - as long as the data is available
Content management server (last version - 2002) has been consumed into MOSS, giving CMS abilities.
A MOSS application can abstract multiple WSS sites under the covers.
Outlook integration is extensive - point outlook at a document library and items appear in the nav pane and compatible docs can be previewed in the preview pane. By synchronizing a document library, Outlook can make the files available offline. Outlook search can search a document library.
MySite - a bit like igoogle - has webparts that summarize information relevant to them like outlook email, workspaces they have access to, personal links and the standard WSS parts - list, doc libs etc...
MICROSOFT OFFICE SHAREPOINT DESIGNER - like frontpage/vis studio - used to design pages in more detail then the admin pages on the site itself can.
Microsoft wants you to use
SharePoint for human-centric workflows and
BizTalk for machine-centric
workflows.
