Course Description

 PostgreSQL, also known as Postgres, is a free and open-source database. Understanding relational data stores are becoming increasingly important for data scientists and analysts. SQL databases have long been used by businesses to store transactional and business intelligence data. This course is designed to help you learn how to perform common relational database and data science tasks, such as writing advanced queries, data analysis, finding, exploration, and extraction within relational databases, if you need to work with SQL databases. You will learn how to aggregate data, analyze data, retrieve data from multiple tables using table joins, and write more advanced queries in this course.
