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....

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.

This course was an Excellent, Interesting, and knowledgeful game for me. I have been excited to lean SQL and Databases and finally IBM and Coursera let my dream come true. Thanks both of them!

The IBM DB2 database was very buggy and unreliable. I spent much of my time waiting for the database to perform simple computations.

Some instructions could have been more clear.

Overall communication could be done better (if it's needed).

All on all, i am satisfied.

Se requiere un conocimiento en configuracion de enviroments en Python. Veo interesante tener acceso a la plataforma de IBM Cloud.

The labs did not work well and it took a lot of time for me to ask for help on fixing them. Although the course content was good.

It would be great if things got covered in a more structured manner. Week 4 is so damn confusing and took a lot of precious time.

Over all it's an awesome course with good quality content. Highly recommended for new learners who don't know anything about SQL

I wish there was more hands on work, but it seems like you tested me well, because I spent a lot of time working the problems :)

CRIME.CSV file had an incorrect setup (date format), since that part was not part of the learning I think it should be corrected

The content of the course is awesome and full blown, I had to watch some YouTube vids for clarification though on some subjects

Lots of good material. Much of it is a commercial for IBM. Directions for operating within the IBM data structure is outdated.

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

The first course I have encountered with lots of labs that make you research and engage more with the course material.

For non-programmers or people with no computer background, it is a bit difficult to comprehend. But overall it is OK.

I really enjoyed doing this course. But I would be very happier if last or optional module had given more materials.
