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....

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.

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.

El curso esta muy bien desarrollado, realmente se aprende SQL. Los ejercicios para practicar son desafiantes y estan hechos de tal manera en que los conceptos quedan claros.

Took a bit longer than original expected! Good content, but you really have to find the time to focus on writing and refining queries when they don't work first time around.

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.

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.

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.
