SQL Server is one of the most reliable and widely used database management systems, making it an essential tool to add to your professional toolkit. This text-based course takes you from absolute beginner to a confident SQL writer. You will start by understanding database structures and foundational terminology, then progress to writing queries that extract, filter, and aggregate complex datasets. By reading clear explanations and analyzing practical code examples, you will gain the skills needed to design database schemas and write optimized queries for modern applications. What you'll learn: - Understand fundamental database concepts, relational structures, and SQL Server terminology. - Write clean queries to retrieve, filter, sort, and group data from multiple tables. - Apply advanced querying techniques using Common Table Expressions (CTEs) and window functions. - Design and modify database tables, relationships, constraints, and data types. - Query and manipulate modern semi-structured formats like JSON directly within SQL Server. - Practice writing efficient queries and basic indexing strategies to improve database performance.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.
