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!

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.
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.
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.
It was an Awesome course. Really enjoyed doing all the exercises. Now I feel quite confident to write any queries.\n\nSpecial Thanks to Professor Jana Schaich Borg for teaching so wonderfully!!!!!
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!
I recommend this course although the exercise requires more time than the average courses in Coursera. If you complete it seriously on your own you will learn a lot in order to apply it at work.
very detailed introduction of SQL. The only thing is that there could be more videos introduce different functions instead of writing documents as materials. Other than that, it's a great class
It's hard to understand the data that given for quizzes but the teaching of professor Jana is really amazing.when i ask questions in discussion forums there was no tutor to help you out soon.
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.
The exercises and quizzes (particularly the teradata sets) were difficult enough that you have to think and structure your approach to arrive at the right solution. Very good learning curve.
Excellent course for beginners looking to be able to utilize SQL directly or even understand how SQL works so requirements can be gathered with greater detail and why that detail is needed.
thank your for accepting my in the course i really liked studying it i suffered with some difficulties but i survive the course was very good but getting harder by week 4 but interesting
MySQL lessons, quizzes and assignments are very well organised and taught. But was not very happy with the Teradata part. Overall it was a very good course! Jana is a fantastic teacher.
Great course indeed. I read a few negative comments about extensive exercises, but that is the beauty of this Course. These exercises make sure that one has fully grasp over concepts.
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.
It doesn't go into great depth but exposes you enough to SQL to give you a good start and an appreciation of how complex company databases are likely to be.\n\nWorks with real data.
This is a well-designed course with easy-to-follow instructions and great exercises.\n\nI've tried other SQL courses on Coursera and this is definitely the best one for beginners.
This is an excellent course indeed. Access to real world data is a huge +. Some of the questions in the quizzes were difficult though. And also the witty jokes by the Prof... :):)
Very practical and challenging! However the Teradata content is much more overwhelming than the MySQL content due to its format (MySQL parts were explained thoroughly in Jupyter).

Will I receive a transcript from Duke University for completing this course?
No. Completion of a Coursera course does not earn you academic credit from Duke; therefore, Duke is not able to provide you with a university transcript. However, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
