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.

This course is very detailed and applied, while also providing enough theory first to help you understand the underlying concepts. It is quite challenging and especially last weeks exercises and quiz will test your limits. But this is just the finale of a really great course. The community also is very helpful. Highly recommended!

Week 5 is extremely hard in which you got to write very complex queries. But it's worth it in the end. You feel that you've learned a lot

Great course about database.

This course come from basic background in Relational database rather then go detail to syntax SQL.

Beside that, it provide real big dataset (around 100 million records, woa)

Thanks for creating such great course

This is a well-designed course with easy-to-follow instructions and great exercises.

I've tried other SQL courses on Coursera and this is definitely the best one for beginners.
