SQL Server is a relational database management system (RDBMS) developed by Microsoft and implements the Structured Query Language(SQL). It supports a wide variety of transaction processing, business intelligence, and analytic applications in corporate IT environments.
MS SQL Server has an excellent Data Restoration and Recovery Mechanism that allows you to recover and restore the lost or corrupted data from caching, log files, and backups.
SQL Server programmers can truncate a database query during execution without killing the entire process. Also, it uses a transactional engine to keep the state consistent.
There are several reliable online support options for helping DBA administrators deal with issues and problems in developing, implementing, and maintaining MS SQL database.
With SQL Server Express, you can take advantage of Row-Level Security, Always Encrypted, basic and fine-grained auditing and Dynamic Data Masking features.
SQL Server does not block the database while backing up data. The feature enables users to back up and restore a huge amount of data without putting extra time and effort.
