Acerca del Curso

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.

Great content, but this was over kill. The course was useful but I found it extremely straining to have to use 2 platforms (Jupyter and Teradata). I pretty much had to keep thinking everything twice, and it was over complicated especially that the Teradata website doesn't run smoothly and had many connection issues.

I was continuing with this course and have completed 2 weeks, but the Teradata Viewpoint doesn't seem to work. I am trying for the past 2 days and hence, I will not be able to continue this course. I liked the first 2 weeks though.

Good, difficult course.

Materials have errors from a long time ago and no one seems to be updating it. These errors are wasting students a lot of time. Mentors and staffs respond to posts in a polite and timely manner.

the instructions of the final assignment seems a littble bit confusing. Many have reported the issues but the staffs didn't respond in time and the materials haven't been updated for a period.

Very interesting and hands on course. But not a lot of maintenance, explanations and assistance on the questions, especially the Teradata exercises.

The content is there but often poorly delivered, the videos aren't much help and it feels like the course is not setting you up for success.

Is a great course, However, I Think some materials could be explained more by the professor, and not just for the student read.

A great course! However, some logistic mistakes prevent me from finishing the course. (Teradata account info)

there are so little video tutorials, and too many exercises without video instructions.

Week 4 excercises are hosted on an external server which (at least for me) was impossible to be accessed. I have tried to extend the timout in my browser but it still would not work! This seems to be an inssue to many students yet nobody has looked into fixing this issue.

there's a bit jump from whats taught and whats tested. some of the important elements are in the text Practice Section that should have been in video form showing us how to do it.

Errors in the material made it difficult to get through. All past discussions on the forum are gone, making it difficult to review posts by classmates.

Very hard to navigate Teradata as it is has many bugs and issues. Quit the course mid way just to save time. It is so frustrating.

The technical support of this course is just terrible: just like many many other students (see the Discussion forums), I have experienced serious difficulties to access the databases platforms we need to learn and to complete our assignments. I can only echo the innumerable complains from my co-students about the lack of efficient support and technical reliability of this course; many of us are very unhappy about this, especially as they have paid for this course ... and what is Coursera doing about it, by the way?

My advice: beware before enrolling in this course and even in this entire specialization, and search for alternative options (there are many, not only on Coursera but also on EdX and others ...)!!!
