SQL Server editions
The following table describes the editions of SQL Server.
| Edition | Definition |
|---|---|
| Enterprise | The premium offering, SQL Server Enterprise edition delivers comprehensive high-end datacenter capabilities with blazing-fast performance, unlimited virtualization 1, and end-to-end business intelligence, enabling high service levels for mission-critical workloads and end-user access to data insights. Enterprise edition is available for evaluation. An evaluation deployment is available for 180 days. For more information, see SQL Server Licensing Resources and Documents. |
| 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 (including choosing Web edition on IaaS on Azure) 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 edition | SQL Server 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 edition 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 SQL Server Licensing Resources and Documents.
Use 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.
SQL Server components
SQL Server 2022 (16.x) on Linux supports the SQL Server Database Engine. The following table describes the features in the Database Engine.
| 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, and in database analytics integration. |
Developer, Enterprise Core, and Evaluation editions
For features supported by Developer, Enterprise Core, and Evaluation editions, see features listed for the SQL Server Enterprise edition in the following tables.
The Developer edition continues to support only one client for SQL Server Distributed Replay.
