Why take this course?
ThisΒ course is meticulously designed to transform your understanding of SQL and analytic functions, equipping you with the skills necessary to harness the power of data. Whether you are a beginner stepping into the world of data analysis or an experienced professional seeking to deepen your expertise, this course will guide you through the essential concepts and practical applications of SQL Server and SQL Server Management Studio (SSMS).
Course Overview
Data analysis has become a critical skill in today’s data-driven world. With the vast amounts of data generated every day, the ability to analyze and interpret this data efficiently is invaluable. This course focuses on using SQL and analytic functions within SQL Server to unlock insights and make data-driven decisions.
The course begins with an introduction to SQL, the standard language for relational database management systems, and Transact-SQL (T-SQL), Microsoft’s extension to SQL. You’ll learn about the basics of analyzing data with SQL and how it can be applied in various scenarios. We will guide you through the installation and setup process of SQL Server and SSMS, ensuring you have the right tools to start your journey.
Once the setup is complete, we’ll delve into executing queries using SSMS, covering everything from basic database concepts to advanced querying techniques. The core of the course focuses on analytic functions, a powerful feature in SQL that allows for complex data analysis. You’ll learn the syntax and practical applications of various analytic functions, including ROW_NUMBER(), RANK(), DENSE_RANK(), LAG(), LEAD(), FIRST_VALUE(), LAST_VALUE(), CUME_DIST, VARP, and NTILE().
