About the Course

Working knowledge of SQL (or Structured Query Language) is a must for data professionals like Data Scientists, Data Analysts and Data Engineers. Much of the world's data resides in databases. SQL is a powerful language used for communicating with and extracting data from databases. In this course you will learn SQL inside out- from the very basics of Select statements to advanced concepts like JOINs. You will: -write foundational SQL statements like: SELECT, INSERT, UPDATE, and DELETE -filter result sets, use WHERE, COUNT, DISTINCT, and LIMIT clauses -differentiate between DML & DDL -CREATE, ALTER, DROP and load tables -use string patterns and ranges; ORDER and GROUP result sets, and built-in database functions -build sub-queries and query data from multiple tables -access databases as a data scientist using Jupyter notebooks with SQL and Python -work with advanced concepts like Stored Procedures, Views, ACID Transactions, Inner & Outer JOINs through hands-on labs and projects You will practice building SQL queries, work with real databases on the Cloud, and use real data science tools. In the final project you’ll analyze multiple real-world datasets to demonstrate your skills....

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!

I am thankful to coursera for providing database and sql for data science course in such a way that anyone can

understand the basic fundamental of sql and database. I learn a lot from this course.

The material covered in the course is very interesting and has a lot of potential, however the course itself (especially the labs) is not curated at all. I, alongside multiple students as I have observed in the forums, have faced countless bugs when attempting the labs. Each one presented a new problem, hence I found it difficult to keep motivated to finish the course due to this frustrating dynamic.

The first three weeks are good, but weeks four and five are a mess. Overall, the sluggish IBM virtual cloud and the misleading instruction images caused me to reconsider the quality of the IBM courses. This was not my first time taking IBM courses. I had a similar experience with the first five courses of the IBM Data Science Professional Certificate.

There were a lot of problems with the online tools needed for this curse. Staff members eventually responded and solved them, but because of it, I went over my time limit and had to pay another month's coursera fees. Seeing as this is an IBM course and the tools were from IBM, I was expecting a smoother experience

This course is a "Big MESS" to me. SQL they used is completely different. It doesn't accept the normal SQL statements. Column names are case sensitive and Writing the where clause gave me head-ace. It wouldn't accept the straight comparisons. Columns names should be expressed in quotes.I hate this course

People knowing some SQL will learn next to nothing. For complete beginners there is way too much emphasis on using the semi-unusable IBM cloud platform instead of learning SQL. The assignments are also too easy and short, which means you don't get to actually practice the bit of SQL you could learn.

If you know nothing about SQL, don't take this course since it just a brief introduction without any in-depth explanation. By no means, a beginner can understand what SQL is in this way. But if you've already known something about SQL, it's good for refreshing your knowledge.

This was over challenging because labs and lectures definitely lack decent level explanations to learn the content permanently. I can't say I learned nothing, but I can clearly say this is a below mediocre level of training.

1) Material and presentation was not engaging and structured

2) Final assignment in terms of administration (copy pastes and screenshots upload) was a pain in the ass

3) Not enough hands on exercises

A lot of the "optional" materials are actually quite important. UC Davis's SQL course is far superior to this one due to more access to coding practice assignments. I expected more from IBM.

Lots of slides with bland voiceovers. No actual tutoring or use of graphics to help explain difficult concepts. Errors in the exercises. Gave up in Week 3 because it was too frustrating.

I expected a more detailed explanation in templates. as it was done in the previous course (Python for Data Science and AI). since this database theme is done with many procedures

We spend more time debugging and googling to get things to work than the actual project time. The forum is full of this, but the IBM guys do nothing. This is putrid it tell you!

Would be awesome with a few corrections and updates to course materials- more concise and clear instructions would also be helpful for this beginner level course.

Some of the exercises missed crucial instructions. If I didn't already have experience in SQL this course would have been unnecessarily difficult to complete.

Any screenshot referring to ibm cloud is clearly outdated as it does not match with the current website. Instructions on how to get db2 connection credentials are MISSING and the ibm cloud website is not at all intuitive. There is no way to change the default uid/password for db2 connection and there are no instructions either in the ibm cloud site or in this course.

I just spent almost an hour trying to solve this problem but in vain. I should not be wasting time and resources trying to establish a stupid database connection.

For $39 plus tax per month this is not only disappointing but robbery!

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.

Week 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.
