Sobre o curso

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....

This course was OK, but I'd still like to see more hands-on exercises and a final assignment that's more aligned to the prior coursework

Assignment marked by other classmates is not a correct method. classmates often do not read answer carefully and give a correct grade.

Does a good job explaining SQL queries. But the final assignment has to be designed better. There are too many repetitive questions.

The last exercise of the last week is not clear how to do it and the server does not run it. There is no assistance from the forum.

I had difficulty accessing libraries and found discrepancies between instructions and IBM UI.

The course material was pretty good.

Instructions for the labs were not clear and indeed IBM DB2 was a little laggy and was not quite an easy platform for a beginner.

For those who have never worked with SQL this is a good course. For anyone who has worked with SQL, it's like rain in the wet.

It's nice and it teaches you about SQL, but it lacks practice exercises and sometimes is oversimplified and can be too easy.

T​he content of the course is good, but the coding notebooks of the last weeks are full of bugs, which is quite irretating.

You should use DB2 to complet it but if you can't there is no support and the alternative in mysql does't work as well .

The final project might need to be reviewed. So much time was spent trying to load one of the .csv files without error!

Very bad online SQL system. Very complicated and buggy. You get lots of errors when you want to upload a CSV file.

Many dead links and typos in the course. Plus the Lab is down. Great content but this course should be reviewed.

Some good exercises and material, but I was hindered for several frustrating weeks by technical problems.

an unnecessary emphasis on using ibm tools which many times don't get interconnected is a big turn-down.

A good starter course with good insights for those who are new to SQL and using Python for Data Science

It has the most basic about databases and how to connect python with an database instance on IBM Cloud.

The evaluation system is more theoretical than practical. Working with the IBM DB2 cloud is tedious.
