This course is an introduction to how to use relational databases in business analysis. You will learn how relational databases work, and how to use entity-relationship diagrams to display the structure of the data held within them. This knowledge will help you understand how data needs to be collected in business contexts, and help you identify features you want to consider if you are involved in implementing new data collection efforts. You will also learn how to execute the most useful query and table aggregation statements for business analysts, and practice using them with real databases. No more waiting 48 hours for someone else in the company to provide data to you – you will be able to get the data by yourself! By the end of this course, you will have a clear understanding of how relational databases work, and have a portfolio of queries you can show potential employers. Businesses are collecting increasing amounts of information with the hope that data will yield novel insights into how to improve businesses. Analysts that understand how to access this data – this means you! – will have a strong competitive advantage in this data-smitten business world....

Great course! It takes you from zero knowledge of SQL to being able to write quite complicated queries, and being ready for most of standard SQL questions in job interviews. Strongly recommended!

Great course. Gave it 4 stars instead of 5 because I wish it had more video instruction as opposed to documents. I find videos a lot easier to learn on.

Students need access to Teradata to complete the course, BUT the page providing login information is BROKEN. I have to quit in the middle of the course. That is a waste of our money and time!

By providing those messy database which is the case in reality this class really improves our way of thinking when it comes to writing SQL commands. Also those operators and functions are really useful taught in this class.
