Structured Query Language (SQL) is widely used to manage relational databases and perform various data-related operations. Non-expert programmers commonly try to solve a problem with a risky and ineffective solution, also known as an antipattern. Such common bad practices initially look like a good solution and are easier to implement but cause more problems. This course explains the best fixes by addressing multiple antipatterns.

This course covers the following four types of SQL antipatterns: logical, physical, query, and application development antipatterns. Specific examples are curated to help you understand each antipattern and how to solve the real-world problem with a zero-risk solution. It offers a hands-on coding experience to help you understand every concept.

By the end of this course, you’ll be familiar with the anatomies of antipatterns and have a set of rules to follow when solving a database challenge or making up for your errors.
