Microsoft SQL Server 2022 is loaded with exciting new features and enhancements to the core database engine, performance, and security. The following diagram gives a high-level representation of SQL Server 2022.
Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet).
The history of Microsoft SQL Server begins with the first Microsoft SQL Server product – SQL Server 1.0, a 16-bit server for the OS/2 operating system in 1989 – and extends to the current day.
The following versions are supported by Microsoft:
SQL Server 2019 Developer is a full-featured free edition, licensed for use as a development and test database in a non-production environment.
SQL Server 2019 Express is a free edition of SQL Server, ideal for development and production for desktop, web, and small server applications.
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.|

|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.|
