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.

Very good course for learning SQL - the tutorials, materials and exercises provided are very well thought and structured. The staff put lot of effort and thinking into this one. I like the whole specialization and I can recommend taking it.

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.

This is by far the most comprehensive SQL course I have ever taken. A lot of times there are SQL classes that are online that give you a glimpse into what it takes to be great at SQL queries. This is a must for anyone seriously considering to becoming a data analyst.

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 really gives you a taste of what it is to work with real-company data. I strongly recommend it if you want to master at MySQL. Previously I had done a lot of small courses on web pages such as Codeacademy, but this was so far the most complete one. At the end of the course you will be amazed by the thinh you will be capable to do!
