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....

The SQL in this course is at an introductory level. Great for someone who has not worked with SQL before, but a bit slow if you have SQL experience. I particularly enjoyed the section about integrating Python and SQL.

The course provides an introduction to SQL but some arguments - such as basic syntax - are only presented and not explained in-depth.

On the other hand, the second part of this course features very interesting labs.

It was really great but i had some issues with the Skills Network Lab while working with DB2. I am happy just wanted to make sure other learners don't get the same issues. Thank you so much for the great course

Issues with DB2 loading tables apparently due to different versions was the only technical problem encountered by myself several others (see forum) made me loose a lot of time. Otherwise this is a great course.

It will give you an idea of what can you do with free databases resourses using sql to manipulate relational databases. you'll also utilize jupiter notebooks to query data connecting the notebook to a database.

This was a very interesting course. It was harder than it needed to be due to a few errors in code, but that also made it more interesting and challenging to verify that you were retaining the information.

there are some unnesessary hardships for the students becase either the IBM tools are not working or not available, or becasue the alternative tools are not properly reivewed and thus contanin mistakes.

Course is god enough. However the last assessment is not. Misprints and not clear questions lead to disappointing marks in the end. Also other students marked assessments based on their understanding.

Most of it really good. I think joins should be covered in the base material and there should be less of an emphasis on sub-queries. The Peer Reviewed final was a little confusing in its questioning.

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!

Much important instruction was missing which lead to a delay in submission of the peer assignment. Various errors popped up which had no solution in the discussion forum also. Kindly look into it.

This course was an Excellent, Interesting, and knowledgeful game for me. I have been excited to lean SQL and Databases and finally IBM and Coursera let my dream come true. Thanks both of them!

Covers the basics, but might be a little difficult for a complete beginner. Manageable, but difficult. Needs more help using SQL within a Jupyter Notebook which should be in the earlier labs.

The course is good with all proper content and practices. However, the evaluation technique for screen shots is not very great. Sometimes its quite difficult to get appropriate screen shots.

Overall is a nice course. It was a bit confused because Handson Lab related to each other. It would be nicer to have a short remind from previous labs or better to keep labs independently.

Course was well organized, I found the lab exercise to be useful in learning the material. The quizzes and final project were fair and tested my knowledge of the concepts. Great course!

I liked the way this course is structured and I am really happy with the kind of exercise it contains. It would be really great if more details regarding the python script was provided

Good content. I have learnt a lot :) Please improve the uploading files for the tests. There were several loading errors coming from the files which should not happen at this stage...

This is a good course, and a good refresher with lots of hands on exercises. One area for improvement is explaining the link between the DB, SQL, SQLite, and Python in a clearer way.

I would have rated this course 5 out of 5 if the Skills Network Labs were more stable. The Skills Network labs seemed to give errors such as 'restoring' or 'starting' indefinitely.

It was good for basic knowledge of SQL. It would be better if we could understand more on Joins, Grant functions. But thanks for the great work. It was really good for me personally

There lack of guidance for those who get stuck. The instructors are not available to guide. The discussions might look helpful but they consume our time or say waste a lot of time .

(MINUSES) Was Not enough coding practice, some tech difficulties with DB2 and SQL, not responsive on forums, 24hrs response should be the practice

(PLUSES) otherwise, great course!
