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....

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!

Quite good because of the information. However, if you try to use the same code on Microsoft SQL Sever is useless. Besides, most of the code is disorganized for example use ON statement in the same line of FROM TABLE_NAME

The sql is easy, but the course makes it complicated for no reason. Instructions are incomplete on assignments, and issues are known to teaching staff. Ends up wasting 3 hours of time trying to solve known course issues.

I found the course very dry. Parallel I was doinga python course on Udemy, the 100 day bootcamp, and the contrast with the energy you get from Angela in that course compared to this Coursera course was very stark.....

Excessive time spent on getting stuff to work. Very little added value beyond simple definitions. Peer reviewed assignments are a disaster - people can give points as they wish....

Need to update instructions and screenshots for the ibm cloud site. Instructors dont respond to many questions in the forum and when they do their answers are often breif and vague

the base course is just fine, but the honors course doesn't teah you what you need to know to comfortably complete the final assignment, also it is required for some tracks.

There were a lot of troubleshooting errors that I realise, were not only unique to me. These errors were not addressed properly and I ended googling some of these Issues

The course has big technical issues that slow down the completion. I am quite disappointed by the application utilized in the course. The course lessons are good.

The course overall is good with the content. However, there are some technical difficulties to run the final project and have very little support.

Course content is great but working on IBM DB2 is very confusing. Faced a lot of technical issues where it took a lot of time to deal with.

El contenido es bueno, pero no funcionan todas las practicas y en IBM cloud no me acepto el código para la práctica gratuita en DB2.

The quality of the course material, workshops, and support for this class was abysmal compared to the other classes in this series

IBM Cloud is unavailable very often. I had a lot of problems starting the labs just because the tools were not available.

It has many technical issues with IBM Cloud. I couldn't focus on SQL skills from solving IBM connection problems.

DB2 is out of the marketing not many people want to learn it, maybe it's time to upgrade it to something latest

The use of IBM cloud was really frustrating as it was very slow and didn't work most of the time.

As a serial course in the "specialization", it's too simple, just made the learning path longer.
