このコースについて
Data is the backbone of modern applications, and knowing how to retrieve and manipulate it is a critical skill for any aspiring developer, analyst, or administrator. This course provides a structured path to understanding how databases function and how to interact with them effectively using Transact-SQL.
You will transform from a beginner into a confident SQL user capable of writing precise queries and structuring data efficiently. By learning the logic behind relational databases, you will be able to handle complex data tasks and prepare for more advanced roles in database development or business intelligence.
What you'll learn:
- Understand core database concepts and the structure of SQL Server objects like tables and schemas.
- Write Transact-SQL (T-SQL) queries to retrieve, filter, and sort data from multiple sources.
- Apply data manipulation techniques to accurately insert, update, and delete records.
- Create and manage tables, constraints, and indexes to ensure data integrity and performance.
- Implement logic using Joins, Subqueries, and modern Common Table Expressions (CTEs).
- Practice modern data handling patterns including basic JSON integration and security best practices.
The course begins with essential terminology and foundational definitions before moving into practical query construction. You will progress through written explanations and code snippets that illustrate how to solve real-world data problems step-by-step.
This course is designed for beginners with no prior database experience or those looking to solidify their fundamental T-SQL knowledge. No specialized software or prerequisites are required to start.
