Need sharepoint data related answer

1. How list/library data stored in sharepoint
   2. Ho开发者_如何转开发w/Where Document are saved in sharepoint
   3. Where configurations are saved in sharepoint

As @TheVillageIdiot said, nearly all configuration is stored in SQL. That said, there's no support from Microsoft for querying the SQL directly; they have API's for supported access.

Files "feel" like they're stored on a network file share because of the WebDAV service. Lists "feel" like they're stored in a server-grade Access database because of the ODBC drivers.

Although most configurations are stored in SQL, some of them are in the web.config and other files in SharePoint's IIS virtual directories.

In short all these things Lists, Documents and Configurations go into SQL Server Databases, Content DBs and configuration dbs. You should go to SharePoint.SE for further information.
