[!INCLUDESQL Server 2017]
This article provides details of features supported by the various editions of SQL Server 2017.
For information about other versions, see:
Installation requirements vary based on your application needs. The different editions of [!INCLUDEssNoVersion] accommodate the unique performance, runtime, and price requirements of organizations and individuals. The [!INCLUDEssNoVersion] components that you install also depend on your specific requirements. The following sections help you understand how to make the best choice among the editions and components available in [!INCLUDEssNoVersion].
For the latest release notes and what's new information, see the following:

[!INCLUDE sql-server-editions]
On an Internet server, such as a server that is running Internet Information Services (IIS), you will typically install the [!INCLUDEssNoVersion] client tools. Client tools include the client connectivity components used by an application connecting to an instance of [!INCLUDEssNoVersion].
Note
Although you can install an instance of [!INCLUDEssNoVersion] on a computer that is running IIS, this is typically done only for small Web sites that have a single server computer. Most Web sites have their middle-tier IIS systems on one server or a cluster of servers, and their databases on a separate server or federation of servers.
You can install just the [!INCLUDEssNoVersion] client components on a computer that is running client/server applications that connect directly to an instance of [!INCLUDEssNoVersion]. A client components installation is also a good option if you administer an instance of [!INCLUDEssNoVersion] on a database server, or if you plan to develop [!INCLUDEssNoVersion] applications.
The client tools option installs the following [!INCLUDEssNoVersion] features: backward compatibility components, [!INCLUDEssBIDevStudio], connectivity components, management tools, software development kit, and [!INCLUDEssNoVersion] Books Online components. For more information, see Install SQL Server.
Use the Feature Selection page of the [!INCLUDEssNoVersion] Installation Wizard to select the components to include in an installation of [!INCLUDEssNoVersion]. By default, none of the features in the tree are selected.
Use the information in the following tables to determine the set of features that best fits your needs.
| Server components | Description |
|---|---|
| [!INCLUDEssDEnoversion] | [!INCLUDEssDEnoversion] includes the [!INCLUDEssDE], the core service for storing, processing, and securing data, replication, full-text search, tools for managing relational and XML data, in database analytics integration, and PolyBase integration for access to Hadoop and other heterogeneous data sources, and the [!INCLUDEssDQSnoversion] (DQS) server. |
| [!INCLUDEssASnoversion] | [!INCLUDEssASnoversion] includes the tools for creating and managing online analytical processing (OLAP) and data mining applications. |
| [!INCLUDEssRSnoversion] | [!INCLUDEssRSnoversion] includes server and client components for creating, managing, and deploying tabular, matrix, graphical, and free-form reports. [!INCLUDEssRSnoversion] is also an extensible platform that you can use to develop report applications. |
| [!INCLUDEssISnoversion] | [!INCLUDEssISnoversion] is a set of graphical tools and programmable objects for moving, copying, and transforming data. It also includes the [!INCLUDEssDQSnoversion] (DQS) component for [!INCLUDEssISnoversion]. |

MDS can be configured to manage any domain (products, customers, accounts) and includes hierarchies, granular security, transactions, data versioning, and business rules, as well as an [!INCLUDEssMDSXLS] that can be used to manage data. |
| Machine Learning Services (In-Database) | Machine Learning Services (In-Database) supports distributed, scalable machine learning solutions using enterprise data sources. In SQL Server 2016, the R language was supported. SQL Server 2017 supports R and Python. |
| Machine Learning Server (Standalone) | Machine Learning Server (Standalone) supports deployment of distributed, scalable machine learning solutions on multiple platforms and using multiple enterprise data sources, including Linux and Hadoop. In SQL Server 2016, the R language was supported. SQL Server 2017 supports R and Python. |

| [!INCLUDEssNoVersion] Configuration Manager | [!INCLUDEssNoVersion] Configuration Manager provides basic configuration management for [!INCLUDEssNoVersion] services, server protocols, client protocols, and client aliases. |
| [!INCLUDEssSqlProfiler] | [!INCLUDEssSqlProfiler] provides a graphical user interface to monitor an instance of the [!INCLUDEssDE] or [!INCLUDEssASnoversion]. |
| [!INCLUDEssDE] Tuning Advisor | [!INCLUDEssDE] Tuning Advisor helps create optimal sets of indexes, indexed views, and partitions. |
| Data Quality Client | Provides a highly simple and intuitive graphical user interface to connect to the DQS server, and perform data cleansing operations. It also allows you to centrally monitor various activities performed during the data cleansing operation. |
| [!INCLUDEssBIDevStudio] | [!INCLUDEssBIDevStudio] provides an IDE for building solutions for the Business Intelligence components: [!INCLUDEssASnoversion], [!INCLUDEssRSnoversion], and [!INCLUDEssISnoversion]. (Formerly called Business Intelligence Development Studio). [!INCLUDEssBIDevStudio] also includes "Database Projects", which provides an integrated environment for database developers to carry out all their database design work for any [!INCLUDEssNoVersion] platform (both on and off premise) within Visual Studio.
