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....

One of the best course till now I find on Coursera, well structured everything and practice questions made me feel like real life problems as data were from real database of dognition and ua_dillards.

Nice and well-organized course. I joined this course after self-studying on SQL for a few days. The context is really nice. The only problem is the Teradata is not stable. I tried very hard to login.

Great course, I recommand it without hesitation. However the questions and the answer keys could be a little clearer.

The course instruction is very good. If the Teradata database is improved, the course will deserve 5 star.

Derived attribute was never conveyed in the videos. So kindly add up the concept of derived attribute.

Could use further guided Teradata examples since the syntax does switch from MySql rather often.

The instructions are too wordy, could have been given more concise presentation and exercises.

Some practices are over-done. Doing the Teradata exercise without samples was torture.
