Module 1: Course Overview
Course Description

Upon completion of this course, the student will understand moderately complex database structures and concepts such as data queries, aggregation, complex joins, virtual tables, schema design, development techniques, and tooling.


This course expects the student to already be familiar with development environment set up, basic queries, inner join, left join, right join, cartesian products, basic schema design, views, functions, and table expressions. If all these concepts are foreign, it is suggested that the student enroll in the introduction to SQL course here at Cybrary.

  • Writing complex SQL queries to execute on a database
  • Designing and writing SQL queries to group, filter, and summarize complex data subsets to retrieve specific information
  • Designing and writing queries and subqueries using functions, unions, and joins
  • Application of key techniques to real world problems

To be successful in this course, students need to have a basic understanding of SQL and database systems before they enroll.

Who Should Take this Intermediate SQL Training?

SQL is a query language that is widely used, so it’s something that all IT professionals (beginners and experienced) should know.
