Microsoft Server No.5

Microsoft Office SharePoint Server

Microsoft Office SharePoint Server (MOSS), is part of SharePoint, and runs on top of WSS, and builds on it by adding both core features as well as end user web parts to it. Its main strength is enabling an organization’s information to be organized and aggregated in one central, web-based application and provide a taxonomy for corporate data. MOSS integrates closely with applications in the Microsoft Office suite and adds various features such as hierarchical organization of content areas, enhanced navigation, Single Sign On, personalization features, indexed search, the Business Data Catalog, and in-browser rendering and, in certain cases, editing of Microsoft Office documents. It can also be used to create specialized document-specific libraries, such as Microsoft PowerPoint slide libraries, which can be used to share not only specific slides from a presentation but their design as well. The latest version, MOSS 2007, improves over its predecessor, SPS 2003, in integrating with Microsoft Office applications, enterprise content management (with the integration of Microsoft Content Management Server into MOSS), Enterprise Search, web content management, more specialized document management, records management, Web 2.0 collaboration functionality like blogs and wikis, delivery of information stored in SharePoint via RSS, and the ability to take content and lists offline with Outlook 2007 and Microsoft Access. A MOSS application can abstract multiple WSS sites under the covers.     


MOSS 2007 also comes with two other specific installations:
     SharePoint Server for Search, which exposes only the indexed search Enterprise search      capabilities.
     Microsoft Office Forms Server, which is a stand-alone installation of the Infopath Forms      Services feature.


Architecture

The architecture is composed of Web Server front ends running the WSS application with MOSS plugging-in functionality where required, generally a search service which crawls the data store creating an index, a number of other services, and the database back-end, a standard enterprise architecture.
As such it can be built out by load balancing more web servers on the front end and building larger clusters of SQL Server on the back-end. Though recommended to be installed on physical machines, virtualization has been used with MOSS and the previous marks to create this architecture, though not officially supported at the time of writing.
SharePoint allows administrators to create Web Applications each on its own port. A separate web application on a separate port can contain site collections, each having its own database in SQL Server. Site collections can have sites which can contain subsites. A web server can contain hundreds of site collections.
One of the weaknesses of the tool is its own ease of use. Administrators may be tempted to start one port 80 and build a single site collection with sub-sites underneath, exposed to the company as a home page and sub-pages. Though this makes logical sense for a large organization or one with bespoke portals using custom Web Parts or Forms Server, it can cause problems. All the sites in a site collection will be stored in the same database, which can become too large to effectively back-up. Moreover, bespoke development using the same Web Application and Application pool can bring a company-wide internet down.
MOSS 2007 also allows content types and document libraries to have information management policies, which allows the triggering of workflow or deletion of information after a certain fixed event or time period, helping to reduce many of the size-growth problems of earlier versions.


Features
Office 2007 integration
MOSS integrates closely with Microsoft Office applications. It can render Microsoft Office documents in web pages. In addition, with the proper server side infrastructure, it can allow the documents to be edited from within the browser as well. For other document types in a document library, Microsoft Office applications can directly edit the document in the document library. This feature is available for Microsoft Excel and Microsoft InfoPath. Using Excel Services, MOSS can allow Excel 2007 workbooks to be loaded, edited, and displayed in a SharePoint page. All calculations happen on the MOSS server. MOSS can also host and render Microsoft InfoPath forms using the Infopath Forms Services to have it viewed and filled out using a browser.  

Microsoft Office Outlook can also be used for accessing and synchronizing SharePoint document libraries. On connecting a document library with Outlook, the library will be listed in the navigation pane, and the files in it will be listed along with certain metadata such as author. Compatible Microsoft Office documents will be previewed in the preview pane and Microsoft Office Outlook search bars can be used to search the libraries as well. The search entered using the Outlook bar will be federated to the SharePoint server, and the results will be displayed in Outlook itself. By synchronizing a document library, Outlook can make the files available offline, which can be opened and edited using other Microsoft Office 2007 applications; the changes will be synchronized back to the SharePoint library by Outlook.

While it is not necessary to use Microsoft Office 2007 to take advantage of the integration with the Microsoft Office suite, it offers the most integration with MOSS 2007. A few examples of the improved integration with Office 2007 include:
   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.
