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.

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.

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.

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

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.

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.

A great course about SQL and Databases but the final assignment should have been about writing python code to access database and analyze data, as shown in one of the videos where a pandas dataframe was created. Instead, the assignment made us write SQL code inside Jupyter Notebook. That was not needed at least as far as I am concerned. If we had to write SQL, we could have just done it on IBM Db2 Cloud.
