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 about database.

This course come from basic background in Relational database rather then go detail to syntax SQL.

Beside that, it provide real big dataset (around 100 million records, woa)

Thanks for creating such great course

Questions for exercises are written in an overly complex way. I often got stuck because I didn't understand what the lecturer wants from me. And my English is C1.

The rest is good. Nice practical datasets, clear explanation of the subject.

This is a really great course for learning MySQL and Teradata. Coming from a background where I've never studied computers or programming, this course was relatively easy to follow (though Teradata was definitely a challenge for me). I found the instructor pleasant and clear in describing query-writing. There were a few times that I thought we needed more explanation (especially for some of the Teradata exercises), but what is learning without a bit of challenge?! I am really excited to get into the field of data analytics, and this course has helped to open doors for me! I highly recommend taking this course - but be prepared to spend many hours in weeks 4 and 5, as the exercises can be extremely difficult.

Week 5 is extremely hard in which you got to write very complex queries. But it's worth it in the end. You feel that you've learned a lot

The course is exceptional! I am a person with non-technical background and loved how all the assignments were so comprehensively laid out which made them easy to follow.

I just felt the last week was quite heavy in comparison with other weeks. Had I practiced the same level of questions in weeks earlier, I would have completed it in less time.

No other complaints. If you are new to the language it is good course to begin with.
