SQL Server is a relational database management system launched by Microsoft. After partial expansion by Microsoft, it became SQL for operations. The initial version was only suitable for database management of small and medium-sized enterprises, but in recent years SQL Server has continuously expanded to a wider scope of applications. Now, it can be applied to database management at large-scale, multinational companies.
