Acerca del Curso

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....

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.

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...

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!

The course starts from the basics but progresses to intermediate level concepts in SQL, like joins and subqueries, which are required for day to day work in the Software industry.

This "

Databases and SQL for Data Science" course was good. I learned too many new things and it really helped me by providing fundamental knowledge regarding databases and SQL.

This was an excellent course even though it was challenging. I was able to move from introductory SQL to Intermediate level. I really, really enjoyed the practice exercises.

A really good course. The lab assignments improves the efficacy of the course and enhances your conceptual understanding of the requirements of cloud databases in data science

Good course on the basics of SQL. I was surprised that it didn't cover JOINS in the main section of the course, but you get the option to take it as a bonus, that's a plus.

I am so much glad to learn Databases and sql for data science and completed my certification.

I strongly recommended this course who does not know any thing about database.

There are many technical issues in IBM Watson Studio but due to the availability of peer community, the messages in discussions helped me a lot to completed this course.

Not bad, but for me, again, is to many online tools. From my point of view, some Docker Compose with the prepared container(for bd, for notebook) will be more suitable.

greate class. Took me longer to complete these one. But over all a greate class. It got me the data analyst position I currently have now. with almost double my pay.

The final assignment lab using the Jupyter Notebook did not work/load.

It was also hard to see the screenshots of the SQL query and results for the final assignment.

I learn't more about querying databases and creating connection between data base and python using jupter notebook, and one intresting thing i learn is the SQL magic

Course was great but RDBS in browser was so slow that i need to wait for couple of minutes to create a table. Thankfully, doing the same in python took few seconds

Tough start, really boring material and I hoped I never needed to work with SQL. Later though it started to click a bit better and was (slightly) more enjoyable.

This course is best for beginners to get started with the database and sql with ibm cloud. But the content can be improved more as the assignments is concerned.
