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 really awesome!

There are a lot of well designed exercises, which not only trained my skill to write SQL query but also deepen my understanding of relational database. The real business data provides learners an opportunity to get in touch with the real business world.

So I am excited to recommend you to take this course. If you are a new beginner at MySQL, it can help you get started soon. If you already know some basic knowledge about SQL, this course will also be a good resource for practice.

This was one of the best courses I've ever taken. Each lesson built on its predecessor logically. I worked hard to learn each of the concepts, but was very impressed by how much I had learned by the end of the course.

A good challenge for those who want to feel confident querying databases. It forces you to work through the processes and as a result the learnings are much more substantial. I am very glad I took and see immediate benefits in my job.

It doesn't go into great depth but exposes you enough to SQL to give you a good start and an appreciation of how complex company databases are likely to be.

Works with real data.
