About the SQL Server Database Engine

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 Install SQL Server 2012 from the Installation Wizard (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

  • Data Quality Services – is an optional component

    Note Note

    In this release, selecting the Data Quality Services check box in setup does not install the Data Quality Services (DQS) server. You will have to perform additional steps post installation to install DQS server. For more information, see Install Data Quality Services.

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

  • Data Quality Client

  • Integration Services

  • Connectivity components

  • Programming models

  • Management tools

  • Management Studio

  • Documentation components
