The Database Engine component of SQL Server is the core service for storing, processing, and securing data. The Database Engine provides controlled access and rapid transaction processing to meet the requirements of the most demanding data consuming applications in your enterprise.

SQL Server supports up to 50 instances of the Database Engine on a single computer. To create a typical SQL Server installation, see How to: Install SQL Server 2008 (Setup).

Important   For local installations, you must run Setup as an administrator. If you install SQL Server from a remote share, you must use a domain account that has read and execute permissions on the remote share.

The following features are installed when you select SQL Server Database Engine on the Components to Install page of the SQL Server Installation Wizard:

• Database Engine
  
• Replication - is an optional component
  
• Full-Text Search - is an optional component
  

The following additional features are options for many typical user scenarios:

• Integration Services
  
• Connectivity components
  
• Programming models
  
• Management tools
  
• Management Studio
  
• SQL Server Books Online
  

Note:
By default, sample databases and sample code are not installed as part of SQL Server Setup. To install sample databases and sample code, see the CodePlex Web site.
