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.

SQL is useful stuff, and the other courses in this track (data science professional certificate) are great, but this course has way, way too many errors in assignments, workbooks etc. The course material needs a major overhaul to make sure

1. Assignment problems are clearly and unambiguously defined

2. Example syntax actually works in the SQL dialect being used in the notebook

3. When saying stuff like "create table like in week 2 Lab 1, part II", make sure that part 2 of lab 1 in week 2 actually has anything to do with creating tables (it currently does not), etc.

4. When saying "replace the part in angled brackets below with...", make sure there actually is a part in angles brackets below

Etc. etc.;I have wasted a lot of frustrating time trying to figure out stuff that had nothing to do with SQL because of the sheer amount of errors and inaccuracies like this in this course.

Graded peer assignment links are not working. It seems no one actively maintains the course content. Never expected this from IBM

The beginning started simple enough to follow. The learning curve jumps from 0 to 100 in a short time. Not an ideal intro course. The labs are much more complex than what is taught. Instructions how to restart and operate a Run a new SQL was not shown and I had to spend lots of time trying to figure it out on my own. The powerpoints and information are easy to follow but the ease of use through IBM's platform is not friendly. Definitely easier places to learn as I have taken other courses online for intro SQL. I wouldn't recommend purchasing this. I'd either use it in a Free Trial or Audit it. For that value, you can spend your money elsewhere.

1. Lots of the slides have repetitive content, for Ex. different type of joins, Every slide have some repeating lines/audio. Could have taken some different use case or else could have combined it making it a single slide for each joins.

2. The "Table Loading Issue" its been a week now I am facing this issue, even have posted in the forum, the solution provided is also not working. Every time I try loading the table in db2 it fails, without giving any error/warning message. I am almost done except a few assignments and final peer graded assignment due to this I am not able to complete my course.

I did not find the course structure, contents, way of teaching at all good.

I spent more time figuring out how to upload data on IBM DB2 storage than practising. I feel in this course coursera must look into ways to make it more learnable, I seriously will say, I was unable to learn anything from this course I had to spend alot of time on google and other learning websites to figure out how to code in SQL.

In many assignments I just had to skip them because connecting to IBM is very stressful and difficult thats why I was mostly able not to connect with it.

Course just not particularly well designed. There are typos throughout, several of the instructions are outdated (DB2 interface has changed and course has not been updated to reflect the changes). Some of the answers to the problems do not work. Some questions are poorly worded and the solutions provided are not for exactly what was asked in the question. Course spends a large amount of time on relatively simple material and then quickly flies through more advanced material by giving one example but not actually explaining how the queries/functions work.

The main reason for my low rating is the following:

1. The endless issues with the db2 console - an absolute nightmare to work with if you are not in the USA. Horrible experience. This slowed my progress down significantly to the point where I no longer wanted to carry on with this course

2.Not enough practical examples - as a result when doing the assignment, you want to tear out your hair. By my estimate, the Assignment should take no more than an hour if you have worked through everything.

Nice content, but lot of struggles with the tools. Watson studio has updated/changed the layout since the course was created, the content and description of the tasks in many cases don't live up to the real life situation. That's very frustrating, and you can see lots of people experience it if you check the weekly discussion forum. If the tool worked better (and if it would be better descried, as for somebody who never worked in Watson studio before) it would have been 5 stars.

they need to make sure that if an honors course is offered and it's completed and passed, that that student gets a prompt honors' certificate as was clearly stated in the course, instead of that student trying to contact/get help from unhelpful staff (whose second language is english) that ignore your pointed questions, pass the buck and don't help you resolve your issues. the coursera staff needs to get it together because they're highly inadequate and it shows.

I don't think the peer graded assignment is reviewed objectively based on the rubrics. The reviewer did not leave any comments about my "wrong" answers. I can not find where I did wrong as I already included the required clause in the query statements and got the right results. This is somehow disappointing. Even though I passed the course, but I got a lower score than I expected. I did not get any information about my "wrong" answer.

Lab was down for the entire time and it was really difficult to talk to someone and resolve the problem on time. It took 2 weeks for me to finish the final assignment due to lab issue. It was just waste of time any money spent on subscription. Coursera team said its 3rd party issue and they cant really help. IBM team was not providing the required solution on time. I got help from fellow students from the Forum and from google.

Although the first three weeks of this course were very educational, my motivation dropped considerably due to the difficulties I experienced in the laboratories of the fourth and fifth weeks. Although there were no errors, I got errors again and again and I had to delete and recreate the things I had prepared for the database connection. It was the most tiring course I took under the IBM professional certificate.

So many of the labs contain out of date or broken code, or simply don't work. The course also doesn't explain things properly and requires learners to make massive leaps in understanding and logic with little support. I had to get a friend to help me even get the labs to run, and then explain the content to me.

The only good thing is that I now have a basic understanding of db2 SQL - hence the two stars.

Too complicated to debug about the IBM tools, Its took me a tone of time just wandering to check password and username and too many errors without any solutions. I quite all the course not because I could not understand the content or could not do the exercises or lab, just because of the IBM tool too annoying, complicated and the instructions are out of date, also not details.

I am so far into this program that I can't turn back but level of instruction is ridiculous .. I'm learning more from YouTube than from the actually course the incomplete instruction and explanations are frustrating. Add to it the CONSTANT system issues, they are a distraction and they waste precious time. There is no way this course doesn't require prior knowledge.

it would be more helpful if the resources provided actually worked when needed. Nothing is more frustrating than following the lab instructions and not being able to complete it because the downloaded data wont load into db2. Forget trying to get timely help. That doesn't seem to be a priority for the 'education'.

Not great -- mix of SQL and Python that doesn't do enough SQL. I learned a lot of Python just to make simple database connections and run SQL queries -- it doesn't do justice to Python and isn't very helpful to learn SQL that way. The course would be better with just more SQL, and probably not in IBM cloud services.
