課程概述

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....

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. great example databases. i would suggest renaming the course Managing Big Data with MySQL and TeraData. The Teradata component of the course was very heavy, and all graded pieces of the course used Teradata.

I would also make the assignments graded --- they can be peer reviewed. I think doing the assignments really help, not just completing the quizzes. those are my thoughts.

Fantastic course on SQL for those with no prior exposure. Also addresses basic database structures, relational schemas, and ER diagrams, providing an excellent foundation for further work with data in relational databases.

Learn MySQL and Teradata in one course. Lots of hands on work and help for assignments. The only way I actually learn something. Just do it. I have a SQL server background and had to experience life without CTEs.

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.

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.

Difficult course although I had some previous experience with SQL and MySQL. Working with Teradata for the first time was a valuable experience. About 20 hours of study per week. Regarding queries and data extraction this course goes beyond the basics and after completing the course the student is ready to interact with real-world data using SQL.
