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 class to start learning SQL. Jupyter and Teradata are brilliant choices (web-based interface) that avoid the plain of installation. Real datasets from Dognition and Dillard make exercises much more meaningful. Thank you for the careful design and teaching!

This course in my favorite course for this specialization. I discovered the Coursera by this course. I was looking for an online course at good price to learn the SQL and/or MySQL and I found this course. Finally, I enrolled in this Duke University specialization to do four courses (course 1 to course 4 of the specialization Excel to MySQL) This course gave me all the knowledge I need for the SQL learning and the database. It was difficult because the course is dense, but easy to learn with the instructors and Coursera platform. This course need to be a credit course. I recommend it to everyone.

I'm still in Week 1, but I'm already in love with this course. They give accurate information in a light manner, the exercises are very clear and didactic, and they also give the answers to these exercises which answers all of your potentially uprising questions, alongside with the Video Lectures. It is already giving me the confidence that it will be a great asset to me as a Data Analyst.
