This topic provides details of features supported by the various editions of SQL Server 2019 (15.x).

For information about older versions, see:

Installation requirements vary based on your application needs. The different editions of SQL Server accommodate the unique performance, runtime, and price requirements of organizations and individuals. The SQL Server 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 SQL Server.

The SQL Server Evaluation edition is available for a 180-day trial period.

SQL Server editions

The following table describes the editions of SQL Server.

SQL Server edition Definition Enterprise The premium offering, SQL Server Enterprise edition delivers comprehensive high-end datacenter capabilities with blazing-fast performance, unlimited virtualization1, and end-to-end business intelligence - enabling high service levels for mission-critical workloads and end-user access to data insights. Standard SQL Server Standard edition delivers basic data management and business intelligence database for departments and small organizations to run their applications and supports common development tools for on-premises and cloud - enabling effective database management with minimal IT resources. Web SQL Server Web edition is a low total-cost-of-ownership option for Web hosters and Web VAPs to provide scalability, affordability, and manageability capabilities for small to large-scale Web properties. Developer SQL Server Developer edition lets developers build any kind of application on top of SQL Server. It includes all the functionality of Enterprise edition, but is licensed for use as a development and test system, not as a production server. SQL Server Developer is an ideal choice for people who build and test applications. Express editions Express edition is the entry-level, free database and is ideal for learning and building desktop and small server data-driven applications. It is the best choice for independent software vendors, developers, and hobbyists building client applications. If you need more advanced database features, SQL Server Express can be seamlessly upgraded to other higher end versions of SQL Server. SQL Server Express LocalDB is a lightweight version of Express that has all of its programmability features, runs in user mode and has a fast, zero-configuration installation and a short list of prerequisites.

1 Unlimited virtualization is available on Enterprise Edition for customers with Software Assurance. Deployments must comply with the licensing guide. For more information, see our pricing and licensing page.

Using SQL Server with client/server applications

You can install just the SQL Server client components on a computer that is running client/server applications that connect directly to an instance of SQL Server. A client components installation is also a good option if you administer an instance of SQL Server on a database server, or if you plan to develop SQL Server applications.

The client tools option installs the following SQL Server features: backward compatibility components, SQL Server Data Tools, connectivity components, management tools, software development kit, and SQL Server Books Online components. For more information, see Install SQL Server.

Running with IIS

On an internet server, such as a server that is running Internet Information Services (IIS), you will typically install the SQL Server client tools. Client tools include the client connectivity components used by an application connecting to an instance of SQL Server.

Note Although you can install an instance of SQL Server 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.

Deciding among SQL Server components

Use the Feature Selection page of the SQL Server Installation Wizard to select the components to include in an installation of SQL Server. 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 SQL Server Database Engine SQL Server Database Engine includes the Database Engine, 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 Machine Learning Services to run Python and R scripts with relational data. Analysis Services Analysis Services includes the tools for creating and managing online analytical processing (OLAP) and data mining applications. Reporting Services Reporting Services includes server and client components for creating, managing, and deploying tabular, matrix, graphical, and free-form reports. Reporting Services is also an extensible platform that you can use to develop report applications. Integration Services Integration Services is a set of graphical tools and programmable objects for moving, copying, and transforming data. It also includes the Data Quality Services (DQS) component for Integration Services. Master Data Services Master Data Services (MDS) is the SQL Server solution for master data management. 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 Add-in for Excel 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 2019 (15.x) 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 2019 (15.x) supports R and Python.

Management tools Description SQL Server Management Studio SQL Server Management Studio (SSMS) is an integrated environment to access, configure, manage, administer, and develop components of SQL Server. SSMS lets developers and administrators of all skill levels use SQL Server. The latest edition of SSMS updates SMO, which includes the SQL Assessment API.



Download and install

Management Studio from Download SQL Server Management Studio SQL Server Configuration Manager SQL Server Configuration Manager provides basic configuration management for SQL Server services, server protocols, client protocols, and client aliases. SQL Server Profiler SQL Server Profiler provides a graphical user interface to monitor an instance of the Database Engine or Analysis Services. Database Engine Tuning Advisor Database Engine 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. SQL Server Data Tools SQL Server Data Tools provides an IDE for building solutions for the Business Intelligence components: Analysis Services, Reporting Services, and Integration Services.



(Formerly called Business Intelligence Development Studio).



SQL Server Data Tools also includes "Database Projects", which provides an integrated environment for database developers to carry out all their database design work for any SQL Server platform (both on and off premise) within Visual Studio. Database developers can use the enhanced Server Explorer in Visual Studio to easily create or edit database objects and data, or execute queries. Connectivity Components Installs components for communication between clients and servers, and network libraries for DB-Library, ODBC, and OLE DB.

Documentation Description SQL Server Books Online Core documentation for SQL Server.

Developer and Evaluation Editions For features supported by Developer and Evaluation editions, see features listed for the SQL Server Enterprise Edition in the tables below.

The Developer edition continues to support only 1 client for SQL Server Distributed Replay.
