Microsoft SQL Server (MS SQL) is a relational database management system (RDBMS) developed by Microsoft. It is designed to store and retrieve data as requested by other software applications, whether they run on the same computer or across a network. Here are some key points about MS SQL:

• Core Functionality: It uses Transact-SQL (T-SQL) to interact with the database, allowing for data query, manipulation, and definition.
• Deployment Options: MS SQL can be installed on Windows or Linux, deployed in a Linux container, or on an Azure Virtual Machine.
• Editions: There are various editions of MS SQL Server, each tailored for different workloads and audiences, from small single-machine applications to large, internet-facing applications.
• Components: It includes several components like the Database Engine, SQL Server Integration Services (SSIS), SQL Server Analysis Services (SSAS), and SQL Server Reporting Services (SSRS).
• Machine Learning: MS SQL supports integration with R and Python for machine learning, making it easier to build, retrain, and score models.
