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.

This is by far the most comprehensive SQL course I have ever taken. A lot of times there are SQL classes that are online that give you a glimpse into what it takes to be great at SQL queries. This is a must for anyone seriously considering to becoming a data analyst.

This course is very friendly for people with no MySQL experience before. Now I can write queries to solve problems independently and know how to seek help from online forum like GitHub or StackOverflow. Great thanks to all the teachers and mentors. Love from China.

Great class to start learning SQL. Jupyter and Teradata are brilliant choices (web-based interface) that avoid the plain of installation. Real datasets from Dognition and Dillard make exercises much more meaningful. Thank you for the careful design and teaching!

Very good course taking you from the very basics of SQL all the way up to very long and complicated queries. The final week was difficult but i'm glad I managed it persevere as after completing the entire course I have confidence in my newly learned SQL skills.

Amazing course!! I would recommend it to anyone who wants to learn how to use SQL! I had absolutely no previous knowledge and I loved every minute of it! It was challenging at times, but SO worth it! This is the best course available on Coursera I ever did.

Highly recommend this course for people pursuing careers in data analysis/business intelligence - i.e. those who do not need to know the details of how to set up or optimize databases, but will interact with databases regularly to get data for their work.

Jana, this course is phenomenal. Thank you to the staff and other participants who helped me through this course. Holy cow, it's not for the weak, but the biggest piece of advice: persevere and keep thinking. You'll get it eventually *cries happy tears*

It was very worth the effort. In 5 weeks, you can increase your earning potential and no matter if your main focus is visualization knowing how to extract your own data from the company databases makes you a much more valuable asset to your team.

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.

Great examples and problems to work through that actually challenge your SQL knowledge and best practices going forward. The inclusion of Jupyter notebooks and actual datasets help the course feel authentic and useful in the professional field.

This course provides an enormous amount of practice for SQL queries that other online courses lack. As in some of other online courses, we see instructor writing most of the codes, and there is not a right amount of practice for students.

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

A good challenge for those who want to feel confident querying databases. It forces you to work through the processes and as a result the learnings are much more substantial. I am very glad I took and see immediate benefits in my job.

Awesome course - I learned a TON of SQL. Feel very confident, and expect that I could rely on SQL documentation to develop more advanced queries. It took a lot of time, but if you give your time to this course you will learn SQL.

This course really touched on all the most important aspects of learning how to use a SQL database while also providing many supporting materials for reference. I was very satisfied with the quality of the materials and teaching.

If you choose to follow this course, you will have to invest a lot of time. There are few videos, but you will go through a lot of exercises that will make you learn (or recall, like in my case) SQL in a very effective way.

Best course I've ever taken on coursera because it's all about practice instead of theory - and the quizzes/practice questions are extremely difficult but once you get through it you will definitely say SQL is a skill you own.

It is definitely a challenging course, but one that can really make you learn and feel confident in the real world. It was huge that we got to work with real and messy datasets, this for sure enhance the learning experience.

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.
