Description

Microsoft SQL is a relational database management system developed by Microsoft. It's used to store, retrieve, and manipulate data in databases. Skills in Microsoft SQL range from understanding basic concepts like SQL queries and data types to more advanced tasks such as creating tables, using aggregate functions, and combining data from multiple tables with JOINs. As proficiency increases, users can handle transactions, optimize queries for better performance, and even design complex database schemas. Expertise in Microsoft SQL involves managing large databases, troubleshooting complex issues, and implementing advanced security features. This skill is essential for roles involving data analysis, software development, and database administration.
