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....

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, especially since it's using real (and messy) data. Week 5 quiz gets quite challenging. Some more video lectures would be great.

You will learn from the very basic concept of how relational database to the mechanism behind how to JOIN different data from other tables.

It's a long and hard work along the course but extremely rewarding !

Make sure you learn week by week as they strongly connected in order.

Excellent introduction to SQL if students take the extra time to do the optional exercises and really get comfortable with the SQL syntax and nuances. Engaging and also challenging.

One of the most amazing MOOC courses I have ever taken. From the start, Jana did an excellent job with building the intuition of databases in general and of SQL. The modules (weeks) are organized coherently. The datasets were realistic and challenging (in a great way).

The best aspect of this course is the MySQL exercises, built upon IPython notebook. Personally I have experience with R and Python, yet I still feel like I learned a lot from the exercises. The instructions and lessons as part of the programming exercise were clear and useful, effectively complementing the video lectures and providing hands-on experiences.

The only pity I have is that Coursera stopped providing full access to course materials and Statement of Accomplishment. But that has nothing to do with this course. The instructors seem to provided maximal opportunity for all students, including ones (like me ) who are just 'auditing'.

Overall, a five star rating is a must for this course.

I love this course design, very thoughtful and instructive!! Especially having the real database to practise from, it is great for beginners like myself!

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!

This Course is great for beginners as well as those who already have some concepts regarding Databases. There are plenty of practice exercises and the data sets also help getting in the taste of business data. The key to successfully retrieve the most from the course is going through all the reading material available and the practice exercises which has plenty of guidance.

However I would love to see some video additions covering some query concepts in the exercises and also comparison between teradata and MySQL the two functional databases in use!

Thank you for this course! The learning experience was great

I learned SQL by doing projects at work but this SQL helps me to learn from very basic to the advanced. Some questions why this happened at work before was explained well in the class. That's true that data in the real world is messy and missing.
