In Microsoft Windows® SharePoint™ Services, all website settings and page content types (such as list data, documents in document libraries, and other information types) are stored in a Microsoft SQL Server™ 2000 or Microsoft SQL Server 2000 Desktop Engine (MSDE 2000) database. This is a change from the way they were in SharePoint™ Team Services 1.0, where they were split between the file system and the database. This improvement was made to:
* Enable Windows SharePoint Services to perform well in larger installations. Data in the database can be sorted more quickly than data in the file system.
* Improve server availability. If you have multiple stateless Web servers in a server farm, when one fails, another can take over without losing access to content.
* Improve the integrity of stored data. The possibility of conflicts between database and file system information is removed, and the database can be easily backed up.
The new Windows SharePoint Services architecture eliminates the dependencies on a physical file system for Internet Information Services (IIS) and the local Windows security groups. You can now create a server farm system and host many more websites than you could with SharePoint Team Services.
