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!

Good course, the IBM Cloud SQL DB2 interaction with my python notebook was not ready for prime time , however the concepts in the course were excellent

It gives you more than knowledge, an opportunity to gain knowledge. Its on you to expand on what they teach you, thats were the real learning happens.

I personally already knew a lot of what was covered, but I can also say that they did a great job of explaining SQL for someone who has never used it.

It was really hard for me to connect with IBM db 2 cloud and interface jupyter notebook but by using sqlite db browser i complted the assignment.

Very informative and learned a lot. Some of the assignment expects grading in certainway only even though answer can be logically correct otherwise.

Troubling loading the crime.csv dataset and there was no much support from the team. One has to search a series of options which wasted a lot of time

the line fir writing code in jypiter notebook were limited to one line,

therefor writing code especially in the final assignment was a bit complicated

Very useful hands-on labs looking at real-world data sets. Some of the learning material seemed overly complicated, or I would have given 5 stars.

Excellent course for a beginner to learn in detail if we put a little extra effort, as well as experienced person to learn to work on real data.

Very good for SQL with python. However it could use more interactive testing like the UCDavis program where you can apply the skills more often.

I wish the labs related more to the content, but the courses themselves are easy to follow and are recursive in nature like the code they teach

It is a great experience after all to learn extracting data from multiple tables with subquery & implicit join.

This is definitely something new.

Very Well course!! You can learn sql and relational database concepts without any experience. Also, the difficulty is progressive and balanced.

The course is very interesting, but a bit heavy if you have a pace faster than one week a day. I liked the concepts imparted. Have a nice day

This course is good but little bit fast. Videos needs to chunked down as too many things get covered in single video without proper practice.

Un bon cours concernant l'usage du SQL. Il reste nécessaire de s'appuyer sur des ressources extérieurs pour appréhender au mieux le langage.

This is just a basic course. The course equips you only with basic knowledge of SQL even after completing the honors certificate of week 6.

Excellent basic course for SQL. It needs some time for the assignments and the hands on. There practical part is very important to be done.

Great course with very useful and cohesive content. The IBM db2 software is a bit slow and difficult to access but otherwise a good course

Sometimes a little bit confusing, and also seems to have some lack of information.

Also i had a lot of problem with the ibm cloud platform

The course itself is good. However, some instructions on using IBM Cloud are unclear, so the experience with assignments is not the best.

The course is good; it will have been great however if the PowerPoint of the class was made available to students taking the certificate.

Best Course so far in this series. The labs in week 3 and 4 are especially good, with lots of problems to solve on real-world datasets.

A good level of complexity with enough tutorials to understand it all. Though, sometimes they were repeating something several times...
