What is SQL Server?

SQL Server is a relational database management system (RDBMS) developed by Microsoft. It supports ANSI SQL, the universally accepted Structured Query Language standard, while extending the language through its proprietary implementation called T-SQL (Transact-SQL). Microsoft built SQL Server to compete directly with leading database engines such as MySQL and Oracle, and it remains a top choice for enterprise data management, reporting, and analytics workloads.

Pre-Requisites for SQL Server Installation

Before starting the Microsoft SQL Server download for Windows 10 or Windows 11, your machine should meet the minimum environment requirements listed below to ensure a smooth installation experience.

  • Operating System: Windows 10, Windows 11, or Windows Server (64-bit recommended).
  • .NET Framework: Version 4.6 or later must be installed.
  • Memory: Minimum 1 GB RAM (4 GB or higher recommended for better performance).
  • File System: NTFS-formatted drive with at least 6 GB of free disk space.
