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....

It's a great course, but you should to remember that when you are studying online you must be autonomous and self-teaching, I'm saying this because sometimes in the course you are going to face some drawbacks with the instructions, so my advice is if you find yourself in this situation go to the forum when you need it.

Overall a good course, but it was sometimes difficult to get IBM's Db2 working. Some days, the database wouldn't even open and I couldn't practice. Connecting to the database from a jupyter notebook also caused errors caused by the server or database, which hindered study and practice. Otherwise, a good SQL course.

Dear IBM Program People,

Great Course. I would have preferred not waiting up to one month to get my final assignment reviewed.

That makes irrelevant the efforts a student makes in completing the course as soon as possible to start learning other courses. That is the only reason I give 4 stars.

Best Regards,

Pietro

The course is well-structured and informative, but it is plagued with non-functioning IBM Cloud functionality and by featuring a ton of typos and broken links. If you can make it past these hurdles (and perhaps use a DB server of your own in the process, which I highly recommend), this is well worth your time.

Some automation in the final submission review may save time. Especially where answer is a objective type. For the subjective answers always peer-review is a good option which is in practice. Otherwise, it's a great course helps someone to start their journey in SQL with exposure in IBM cloud space.

A good, but shallow, course for learning basic SQL and Relational Database concepts. Good for those looking to learn the fundamentals and start working hands-on as soon as possible. Those looking to learn beyond the basic should look for other sources in concert with, or instead of, this course.

Great online course if you need to refresh your SQL skills and learn more in-depth. A lot of practice during this class and materials, resources given to link all the dots: DB, SQL, Python. The Course is well explained and quite clear. The Final Assignment looks more complex than what it is.

The only issue was working with the DB-API. It was taking a lot of effort and time to make a connection with the database and was happening repeatedly. However, the forums were helpful and eventually, I was able to resolve it with the solution mentioned by one of the IBM team members.

It is not suitable for beginner in databases.

It is helpful for people who are trying to use Python to access SQL, database APIs basics.

The cons are this course is too focus on how to use IBM tools, instead of problem solving or general knowledge in using Python to connect SQL by APIs.

The course is very excellent however I have faced an issue with IBM DB2cloud .At the time of final assignment submission it was not working and always showing 502 bad request ,So I have faced little obstacles during completion of my final assignment.Otherwise the course is brilliant

Good course with very useful and valuable material. However, there were times when there were issues with loading data to work on assignments. Additionally, IBM updated their cloud system, it can be challenging to follow the course directions because they are not up-to-date.

Peers need to understand the description and the submissions to review the assignments. I have been reviewed as not attempted for Problem 7 and partially mark for a completely correct Problem 9.

I don’t want any person who cannot understand the questions and answers.

The wording of some lab questions were asking for result sets that were a bit different from what the solutions were. Some work on the ambiguity would be appreciated. And incorporating more of the multiple table query concepts in the videos would be better.

It is a good introductory course for individuals who would like to understand the the basics of how to work data (Load data into a database, query for relevant data using primary and foreign keys from different tables) and understand the fundamentals of SQL

I think the course should include as mandatory the week 6 that is noly required for the Engeneer Specialization. I know that joins are crucial in many queries. If you don't know how to implement them I feel you are literally halfway in important SQL skill.

This course was helpful to provide the basics of SQL and how to connect to the databases using API's.

Overall the course was beautifully written and could be helpful for the beginners who have just made the first or baby step in world of data engineering.

well done excellent work i am giving four because you need to improve in the areas add important points such as the schema to be used in the assignment should be similar to the connection made and time stamp should also be included in important section

Hands on LAB was helpful for practicing. Though there were too many terms to memorize that it would have been helpful to actually have a kind of cheat sheet hand out prior to each video lesson to help in understanding and following the lectures.

Tuve problemas importantes a la hora de poder realizar el ejercicio final, no cargaba la base de datos en Jupyter y tuve que hacerlo directamente en DB2 IBM donde ciertos comandos no funcionaban y no lanzaba la información correctamente

This course offers a good first overview of working with SQL and database systems. It relies a bit too much on external IBM tools while a more general approach, with the open to get introduced to IBM tools, would be more appropriate.

Good course; got lost in instructions a few times and had to restart the support programs from scratch but got there in the end. Probably jumped in a little too deep and needed to take a few steps back in what course I chose.

well organized course, the labs and assignments were very helpful to practice and gain skills the only drawback was lack of explanations about some lines of code in the labs, you need to search and understand it your self.

I took this course to refresh my SQL skills. In general, this is a good course, but I think there was a little practice. It will be more useful for students to be required to do more tasks and assignments for asessments.
