课程概述

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.

If you work with data this is an excellent course, but even if you are not a frequent data user you can learn a lot from the logic it explains. I absolutely recommend it.

comprehensive. no need to download or install SQL server offline, all the practices are online browser-based. but require lots of time to practice to complete each week.

Very strong course, the most serious course I took in Coursera! I don't use SQL in my work, but the base knowledge gained on the course has been useful to me many times.

This course is very good for beginners and then goes deeper into the matter. I would be very interested in an advanced course from Jana Schaich Borg, Duke University.

Great course with carefully structured material, and easy-to-absorb, bite-size information. As a student, I don't feel overwhelmed, but feel like I've learned a lot.

LOVE IT! Good for beginner, it will get a little bit complicated at Week 5 tho, but you understood all first 4 weeks' materials, you will eventually get there.

这门课非常有用,第二周的课程相对简单,但是后来三四五周的课程难度逐渐增加。特别到了第五周的考试,需要对前面所有的知识进行融会贯通,灵活运用,才能做出题目。这门课程也让我发现了做一名data analyst确实需要首先静心思考各个datatable的关系逻辑,对自己手里的数据非常熟悉才能更好的完成分析工作,感谢这门课。

Very useful and lots of resources and information, yet you need to search a lot in order to make sure you are qualified enough to start working on your own.
