课程概述

Much of the world's data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands-on and practical learning . As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no-charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only $39 USD per month for access to graded materials and a certificate....

Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.

Clear, thorough, well-designed. Labs give useful practice, assignments and quizzes test the actual instructional content. This course is by far the best in the IBM Data Science specialization.

The lectures could be quite challenging to understand due to the technical jargons used.

it is a very good course that I have learned a lot from, however, I got confused in too many situations when trying to run queries and complete assignments. I dont know why but instead of trying to type the proper query, the course pushed me in a way to find the proper query somewhere, copy it and that's it. A very positive point was the amazing support and quick responses from Rav.

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.

Feels like lectures are being give by an AI instead of an actual teacher. Also some things get repeated in several videos.

Teaches pretty well for people like me that had none previous knowledge in SQL.

I think that could tell a little bit more about SQL outside the IBM platform.

The course is pretty easy and basic, but well constructed and very useful for those who want to get to know SQL.

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

This course is good for anyone who is a complete beginner, new to, or looking to refresh their knowledge of Structured Query Languages (SQL). Ideally would have liked to have a lesson on optimizing SQL queries since many queries become inefficient for data tables with very large row counts, but I understand this didn't make sense since the free IBM DB2 database they have you set up has a size limit of 100 MB. No need for optimization with data this small, but it's still something they should have at least mentioned in the course as an optional lesson. Overall, nice course for learning or refreshing SQL and database concepts.

Apart from errors in the open source tools for the hands on labs, this course is fantastic and well crafted to introduce Databases and SQL. the optional sections are useful for those without good grasp of knowledge about databases and their types. make sure to take them. The labs are good, but always there is connection problems. If they will fix this, it will be one of the best introduction courses out there.

Week 4 was a bit intense and I think the topics could have been decompressed over one more week.

the course is not bad, but for the beginners who don't know anything in this course some lessons are not clear to understand

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.

Good for the basics - will help getting into SQL.
