О курсе

Much of the world's data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands-on and practical learning . As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no-charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only $39 USD per month for access to graded materials and a certificate....

Amazing course for beginners! The entire course is well structured and has good hands-on assignments. SQL is extremely essential for Database management and fun learning so please do try this one out!

A very useful course with some very interesting datasets/Jupyter notebooks to work through/practice your skills. Offers a good balanced blend between theory and practical/practice. Very good course!

The videos do not show the proper syntax (there are no ";" at the end of the queries) and pass over concepts quickly. They begin with "After watching this video, you will know how to do a, b, c, ..." and by the end of the video, I can't say I know any of the content presented.

The creation of the IBM account was complicated as there are many sets of instructions in different places on the course's page.

There was also a mistake in a hands-on lab (which I reported).

I would not recommend this course at all.

W​eek 4 and Week 5 Labs do not work properly due to database connection issues even though this has been a known issue for months. Typos in labs. Rubric for Week 5 Peer-Reviewed Assignment grades on items not asked for in the problems. Why Coursera continues to let IBM courses to be hosted on their website, I will not figure out. These courses need to be removed until IBM resolves these issues. Now certificates are having problems being issued as well.

Worst course on Coursera that I have taken within IBM Data Analyst Professional Certificate program. Things just do not work according to instructions in the course material. It took me a lot of time to solve these issues which don't have anything to do with the course content.

This is a useless course. I've done many courses on Coursera without issues, but I would not recommend this one, mostly because you've got a zero chance of getting any response from anyone if you need clarification or assistance with anything, even completing assignments.

Die Videos sind veraltet und die Plattform von IBM hat sich mittlerweile stark geändert. Ebenfalls treten einige Fehler auf, das ablegen des finalen Testats war nicht möglich, da der Timestam im CSV "Chicago_Crime.." nicht erkannt wird..

The tools used are not very user friendly, I spent more time troubleshooting them than actually learning. It feels like the instructions need to be reworked and ordered correctly.

This course doesn't work. It relies on IBM Cloud that will spit out an ERROR message with every command, even if you copy and paste from the course instructions. Save your money.

Could not finish the course as too many obstacles to resolve. Often, the tools were off-line, instructions did not work and the forum's advice could not resolve the issues.

No clue how to find anything on IBM cloud for the last assignment. How can it be so hard to write clearly how something is done? You are changing money for this.

DB2 instance required in the course can not be created due to repeatable service issue and it naturally stops the following courses.

Poor explanation, lack of tasks and bad developing environment provided. I'm very disappointed with this course.

The db2 instance seems to fail for many people, including myself, preventing us from proceeding with the labs.

Hard to get the IBM cloud products to work. They do sometimes but are not reliable. I am dropping the course.

Very bad teaching. Poor practices, it seems that they just want to promote IBM products rather than to teach.

Labs are always down and time out so you are unable to practice what you are learning.... Very frustrating!

There were problems with the db2 service nearly the entire course and staff were extremely unhelpful.

There were several problems with the labs for several days, and the staff didn't offer any solution.

Not user friendly.

Errors present. Have to do a lot of work-arounds.

Dreading finishing this course.

Sadly, this is the most confusing and error riddled course among all of the courses on coursera.

Boring course. Not application based. No learning by doing.

Boring and monoton lectures.
