About the Course

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 enjoyed it a lot and learned more than I was expecting to. There was a lot of problems towards the end with Teradata, the website was down for a couple of days. A bit more of technical support from the administrator would have been nice.

I won't give 5 stars only because Jupyter from time to time has crashed. Apart from that, I think the course is well done and also the exercises are very helpful.

Thank you for giving me the opportunity to learn MySQL, now it's on me to get better.

It was a great experience learning with all this good content with the best teacher. Just need to improve your service and query problem. I have faced issues while doing the practice of Teradata I complain about it many times but no response.

I prefer have the result of the question. I prefer check the result of my query in order to be sure that I done well. I have lost time to revise my query when they are good and other times I believe my queries are good meanwhile I was wrong.

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.

Excellent course, really helped me learn the fundamentals of SQL. I thought in some cases the questions could have been worded a bit better, but overall I thought the professor provided an excellent basis for me to learn the material. I

This course is very handy to practice SQL as I've never had before. combining SQL with exploratory data analysis provides an amazing opportunity to learn what would happen in real world. The assignments were difficult but enjoyable.

Overall the course was very helpful, the exercises informative, the approach to encourage learners to explore stuff rather than being spoon-fed queries. Thank you, Jana for this wonderful experience, and thank you, Duke University!

An challenging course but I think they go too too fast in the queries, because at the begginig its almost easy for a noob, but in the last week with the subqueries it was too too hard for me to understand what I have to do.

The course is well structured and it really brings you from inertia to coding in SQL (even if not in a high level). I'm more aware now of the relationships by using subqueries and joins, and this is certainly an up.

There are great practices but I don't appreciate the fact that once we are done with the exercises, we are locked out of it. I would definitely have preferred to go back and revisit and refresh every now and then.

Excellent course. the assignments are really challenging and require actual practice at real world problem solving. there are some mistakes in the course materials that took me some precious time to figure out.

The actual amount of time required per week to complete the course was well over the 3-5 hours/week advertised on the course homepage. It was a very time intensive activity each week- especially the last 2 weeks.

The course is great. There are a few problems with Terradata. I think if they offer an extract of the data in spreadsheet form, the problems would be much easier to work with. Overall, the course is good.

A very well designed course with no prior knowledge assumed. The discussion forums are very lively and queries (no pun intended) are responded to fairly quickly. A great option who wants to learn sql.

Very good, detailed course, I can recommend! Before that I knew nothing about SQL, now I have moved to higher level of analyst. Sometimes the instructions are not 100% clear, but it is minor problem.

The notes are perfect! But I do think that the content might be a little bit easy.. Good course for beginners, but if you are looking for more challenges, this might not be the best choice for you.

Its a very good class to learn to use SQL in a systematic manner, even if you had used SQL or are completely new. The two Databases ( Terradata and Dognition) gave a lot of valuable practice.

It's a great course for beginners, maybe being deep into two databases isn't fruitful enough. Web pages like can give more examples, more interesting and with current data

Great SQL course. I think the course overall is well structured and let me stretch myself week over week. It's a little difficult to write long query in SQL scratchpad though.

Very helpful and good course. The main focus is on the practice. There are many exercises which help to practice which in turn helps to understand the concept more.

The course is great , teradata login gave some problems thou , would have been good to have sample data and play around rather then a seperate login for teradata.
