Course Description

This 13-video course explores how indexes work to speed up query execution, and how views can be used to abstract complex queries in a convenient fashion. Learners will explore advanced abstractions in MySQL, including a view, which is a virtual table, and indices. Then you will learn how to use views to build abstractions for complex and common query operations in your use case. You will examine indices, which are auxiliary data structures which are maintained by a DBMS (database management system). Next, learn how to use an index on a database to make queries fast and easy. You will examine normal forms in database design, a standard set of rules to test the design of a table. This course demonstrates how to apply the analysis of normal forms to optimize the structure of your relations, and then to use appropriate indices to speed up query execution on them. Finally, this course demonstrates first, second, and third normal forms, and how to fix violations.
