[!INCLUDE SQL Server -Windows Only]
The [!INCLUDE ssDE] component of [!INCLUDE ssNoVersion] is the core service for storing, processing, and securing data. The [!INCLUDE ssDE] provides controlled access and rapid transaction processing to meet the requirements of the most demanding data consuming applications in your enterprise.
[!INCLUDE ssNoVersion] supports up to 50 instances of the [!INCLUDE ssDE] on a single computer. To create a typical [!INCLUDE ssNoVersion] installation, see Install SQL Server from the Installation Wizard (Setup).
Important
For local installations, you must run Setup as an administrator. If you install [!INCLUDE ssNoVersion] 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 [!INCLUDE ssNoVersion] Installation Wizard:
