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.

One of the best MOOC courses out there! Challenging but you will learn a lot if you stick with it. Extensive and in-depth lectures/practice exercises on SQL. Appreciate that you learn using two systems, MySQL (through Jupyter) and Teradata. However the Teradata interface is a bit clunky and takes time getting used to.

BTW, Jana is a great instructor and Duke courses, in this track, especially the Tableau and MySQL courses are the best out there at the moment.

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.

A lot of work, but totally worth it. I definitely feel like this course does a great job of teaching applied SQL, rather than just teaching you syntax. Highly recommended.

This course is thoroughly satisfying. You can hear the brain churning while trying to figure the most intuitive way to write the queries. It gives you the confidence of working with big data sets, gives an insight into how other cohorts think and helps you rate your own faculties of logic. The course delivers on the promises it makes.. 100%

Useful skill to keep. Jana is well prepared for each course. My company uses other softwares so there are some difference in syntax.

A difficult and time consuming course. Each week the assignments are significantly harder than the previous week. However, you will become fairly sufficient with SQL after completing the course.

Hint to succeed with this course: Utilize the community forum and the search function.
