Introduction to SQL: Multiple Tables and Advanced Queries

Course Overview

As with any development skill in the industry, learning the core fundamentals creates a foundation. In the course, you will learn about multi-table database architecture and design; connecting several tables; and concepts using inner outer joins, equijoins, and non-equijoins. You will also learn about subqueries and advanced queries in SQL; using statements with multiple conditions and multiple joins; new operators; and functions to manage your data. This course also covers Multijoins, UNION operator, and functional dependencies. By the end of these courses, you will be well on your way to creating efficient and easily manageable databases and have fun while doing it.
