Install SQL Server Database Engine
Applies to: SQL Server - Windows only
Overview
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 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.
