课程概述

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....

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 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

multiple times facing issues with external tool, it won't open, the link to download data sets don't work. I couldn't complete the course on time.

Everything else was fine BUT the instruction set for the final assignment was EXTREMELY CONFUSING... unlike any other Coursera course that I took.

the third party tool failed and it was incredibly frustrating to try and move everything to Watson Studio. Once I got that going tho it was fine.

Getting the right syntax for Python and SQL together was really tricky/difficult. I wish there were a reference book/website for additional study.

The basics were easy. The hard part were the instructions in the course didn't tell you all the steps that you needed to do to launch the labs.

Some of the documents which are referring to IBM cloud are outdated. Otherwise this course is really good some one like who is beginner in SQL.

The course was pretty dull in my opinion. My overall thought is that they are trying to impress the student rather than teaching the basics.

I experience with technology issue that caused my time and delay my completion of the course. Hope it will be better in my future courses.

Instruction is overall pretty good, but there are some gaps. Final assignment and tech issues can lead to a rather frustrating experience.

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.

inclusion of proprietary IBM software made understanding the concepts difficult. other than that the ideas covered were good.

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.

The course great. however, some problems was faced during week 4 only. I'm glad about the instructors was doing awesome help.

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

Most course material had errors and would not load, databases would not properly import data tp actually practice querying.

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

So many issues with IBM db2. Videos were good. Kindly add the same interface in labs as its originally present on IBM Db2

Great course for learning how to access Cloud Databases using SQL commands with Python! not so great if you are new to SQL
