課程概述

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....

Amazing course for beginners! The entire course is well structured and has good hands-on assignments. SQL is extremely essential for Database management and fun learning so please do try this one out!

The lessons were short and easy to follow, providing all the basics as well as a few more advanced topics, to get student quickly up-to-speed on databases and SQL and their application in D/S realm.

the instruction in week 4 & 5 lab material can be clearer, as well as setting up a stable connection to the database. i spent a lot of time trying to set up the connection, because it keeps failing even though i used the same code.

In the intro to data science specialization, this course is a relatively steep step up from the previous one 'Data science methodology.' Perhaps obtaining some basic understanding of Python prior to taking this course would help

Overall the course provides the concept of SQL and a great picture. Just with technical issue in the Peer-Graded Assignment, causing spending loads of time to find out the solution, which those time could have been saved.

You will not get any software(MySQL, PostgreSQL) installment process in any videos. They keep explaining thory and give a reading section where you get the real practice. I do not like the way course is designed.

This is a course with a lot of information, but the tutorial is not complete, resulting in a lot of time wasted in the debugging environment. The problem is difficult to solve, which makes me very frustrated

If you have zero knowledge about database and SQL...this should be the right course for you..like me...however, i feel like the course is not very structured and lack materials like questions and exercises.

First student did not check my submission at all gave 0 for all of the questions. I really felt sad because I did correctly for the project. I wish Coursera will do somethings for those mean act.

It's a basic course, I enjoyed the last part where it covers Stored Procedures.

It should emphasize more in just pure SQL and teaching advanced techniques than promoting the use of IBM services.

the course is good but the way they teach you is not as good as other IBM courses it was bit confusing for me where to write the code etc the instructions were not as clear as they should be

Useful course, but the instructors aren't engaging enough in my opinion. I only really felt interested right at the end, when I was trying to work things out in the final assessment.

Could not get the dataset from the assignment, always threw xml error, had to go to some other guys github profile who completed the course, thank fully he attached the dataset used

It should be stated that the exercises need to be completed in Watson Studio because there are errors with the Lab tool. I lost a lot of time doing this module with these errors.

Not super clear and struggles a bit with accessing and connecting to the DB2 I think the examples should match what is on the assignment and really break down the query language.

The labs in this course did not work. This led me to using external platforms for my assignment which took a lot of time to configure and install relevant modules and libraries.

T​he content of the course was good but it should be updated and coorcted. Especially in week 4 I spent more time working on Labs to work than actually working in the Labs.

The speaker in the videos goes too fast. The hands-on labs are very useful and were my primary sources of learning. The videos didn’t help much with the learning process.

The Jupyter Notebook portion was difficult to setup. The instructions for the Jupyter Notebook were incorrect. I had to rely on forum comments to fix the problem.

T​he python portion of the course is not very involved and poor usage of style (lack of upper case SQL keywords) makes learning more difficult than necessary.

The environment is difficult to set up. For someone who knows SQL and has worked on other platforms the IBM Cloud and workspace are difficult to set up.

Content is very good. Problem is that there was many problems with apps/launchers. Many others have had similar problems based on the comment section.

The course is good, but i think that you will provide a platform to practice while watching the videos. In some examples the data base is not upload.

A little to none explanations, very easy quizzes. Low quality slides. Good if you want to remember lines without understanding what they are doing.

Learnt a lot about connecting database from python and how jupyter notebooks are useful.

Please mention IBM DB2 only, if it covers only IBM DB2.

Thanks

The lesson and video itself is okay in general, but the bugs for the labs and assignment is what makes this course very annoying and time consuming.

very short descriptive course, i had previous knowledge of sql so it was much easier for me but for a beginner it was not comprehensive i would say
