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.

By providing those messy database which is the case in reality this class really improves our way of thinking when it comes to writing SQL commands. Also those operators and functions are really useful taught in this class.

Fantastic course on SQL for those with no prior exposure. Also addresses basic database structures, relational schemas, and ER diagrams, providing an excellent foundation for further work with data in relational databases.

The course provided was clear and help me learn about SQL a lot. The only thing that bothered me was the problem with Teradata that wasted me and other learners more than 2 weeks of course time. Keep it up and thankyou!

The course is challenging as it pushed you to deal with real life data set so you not only leaned the language but also how to structure your analysis plan and to execute it. Well designed on-line tools really helped.

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.

Thank you Dr. Borg. Really teaches you SQL from the very basics to an advanced level. Lots of practice. Lots of making you think. This course is significantly longer and more difficult than other courses on Coursera.

Out of the four courses in this specialization, I feel like I have learned something completely new. It challenged me to think in new ways. And in the end, I am walking away from this course with a marketable skill.

Learn MySQL and Teradata in one course. Lots of hands on work and help for assignments. The only way I actually learn something. Just do it. I have a SQL server background and had to experience life without CTEs.

I have to say that this SQL course is perfect. Although this is the second time I learn about SQL, it still gives me some knowledge and the quizzes

are perfect despite there are some minor errors! Thanks Dr. Borg!

This course covers all of the basics in mySQL and Teradata for successful data analysis using sql. I found it challenging but very explanatory while exposing you to common difficulties in the real data world.

The course is very well calibrated. You move step by step from easy SQL queries to pretty complex ones. The connection to the business value of the queries you write is also explained in a convincing way.

Well-structured and well-organized course. Probably the best SQL course I have ever seen. Special thanks to Dillard´s store chain and Dognition for giving an opportunity to work with real business data.

Generally very good experience. The course is tough, but absolutely helpful and rewarding. Supportive as I am, I do hope instructors could update the course materials and correct the mistakes within.

Very well structured course. Not that difficult as i thought but it did take me much more time than I expected. You'd better focus on learning for several hours instead of using short time slot.

very detailed introduction of SQL. The only thing is that there could be more videos introduce different functions instead of writing documents as materials. Other than that, it's a great class

Not only it teaches you how to use MySQL and Teradata in a technical perspective, it also practice the analytical mind and how you would treat a real life dataset when doing analytical work.

The exercises and quizzes (particularly the teradata sets) were difficult enough that you have to think and structure your approach to arrive at the right solution. Very good learning curve.
