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.

It's a great course for beginners, maybe being deep into two databases isn't fruitful enough. Web pages like kaggle.com can give more examples, more interesting and with current data

Great SQL course. I think the course overall is well structured and let me stretch myself week over week. It's a little difficult to write long query in SQL scratchpad though.

Great course. Gave it 4 stars instead of 5 because I wish it had more video instruction as opposed to documents. I find videos a lot easier to learn on.

It's pretty good for entry-level SQL learners. However, to further improve, much time is required. Also, exercises provided are sometimes really weird.

This is one of the awesome course that I studied. A tutor is also very nice she has good knowledge of the subject and hands-on increases my knowledge

Challenging course going from very basic to quite complex SQL queries. Definitely recommended. The only downside are the repetitive technical issues.

great course.. only thing is answers to teradata exercises were not provided. So student cannot know whether he is writing correct sql statements

Very challenging, learned how to write very complex SQL queries. Be prepared to work. This is a 5 week course that took me 9 weeks to complete.

Great course. Enjoyed working through the exercises. Instructions were mostly clear. I feel like the joins could have been explained better.

The course advances rapidly, the later stages are particularly difficult and referring to sources other than this course becomes necessary.

The Content was great, the instructor exceptional, exercises really good. But there were some glitches while accessing Teradata Viewport.

Very well taught, could be better if videos are made where Jane works on SQL examples....walking the student through her solution.

THERE ARE SOME EXERCISES THAT NEED TO BE CORRECTED SINCE THEY HAVE MISTAKES. SOME TIMES IT CAN TAKE HALF A DAY TO LOAN JUPYTER.

WEEK 5 EXERCISES IN TERADA COULD HAVE BEEN LESS TIME CONSUMING IF FEEDBACKS WERE GIVEN FOR EVERY STEPS THAT YOU ACCOPLISHED.

Great course overall! Some areas of course are too wordy which makes it hard to understand what professor is asking for.

The Teradata part is quite challenging and I think it would be better if there are more hints. I like the SQL part more.

Great course, I recommand it without hesitation. However the questions and the answer keys could be a little clearer.

Good, comprehensive training on SQL. The later lessons take longer to complete than those at the beginning.

The course instruction is very good. If the Teradata database is improved, the course will deserve 5 star.

While the material and exercise is very helpful, you may experience some problems with the teradata login.

Derived attribute was never conveyed in the videos. So kindly add up the concept of derived attribute.
