Install SQL Server Database Engine
Applies to: SQL Server (all supported versions) - Windows only
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).
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:
SQL Server Replication - is an optional component
- Machine Learning Services (In-Database) (R and Python) - is an optional component
- R Services (In-Database) - is an optional component
