课程概述

Much of the world's data lives in databases. SQL (or Structured Query Language) is a powerful programming language that is used for communicating with and manipulating data in databases. A working knowledge of databases and SQL is a must for anyone who wants to start a career in Data Engineering, Data Warehousing, Data Analytics, Data Science or Business Intelligence. The purpose of this course is to help you learn and apply foundational and intermediate knowledge of the SQL language, and become familiar with many relational database (RDBMS) concepts along the way. You will start with performing basic Create, Read, Update and Delete (CRUD) operations using CREATE, SELECT, INSERT, UPDATE and DELETE statements. You will then learn to filter, order, sort, and aggregate data. You will work with functions, perform sub-selects and nested queries, as well as JOIN data in multiple tables. You will also work with VIEWS, transactions and create stored procedures. The emphasis in this course is on hands-on, practical learning. As such, you will work with real database systems, use real 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. At the end of the course you will apply and demonstrate your skills with a final project. The SQL skills you learn in this course will be applicable to a variety of RDBMSes such as MySQL, PostgreSQL, IBM Db2, Oracle, SQL Server and others. No prior knowledge of databases, SQL or programming is required, however some basic data literacy is beneficial....

The videos were incredibly basic and didn't require as much practice as expected with real data and querying capabilities overall. It gave you the answer directly instead of a process of elimination. I would have liked more exercises overall with each concept introduced.

Amazing course. Abosolutelly recommended for those who begin in the study of databases. This course gives you an excellent introduction to SQL.

Some of the labs were tedious to get started with because I had to re-create and import data again and again - it may have been my error but maybe a quick module showing how to set up and let these practice data sets persist in the very beginning would be good!

This is the best SQL course I've ever taken! It has tons of hands-on labs, the theory is explained clearly, and you even get to work with IBM DB2.

Solid but I wish there was more interaction, not just a monologue. It teaches you the basics, but some more in-depth explanations and personalization would go a long way.

Wanted to give 4.5 stars but there was no option like this was an amazing course for any beginners. Anybody who want to use Sql in any form should take this course as a revision. There are two languages being used namely Mysql and H2 from IBM database. Course focuses on practical part rather than theory although some of the theory part is being taken care of.

This course is very useful and straightforward. Unfortunately, I couldn't download my Honor Certificate although I completed and passed all the courses including the extra to get the Honor

Login to Cloud was little challenging to practice syntax. It could be more grateful if it is accessible easily

lab exercises are the same questions and answers as the examples taught in the lesson. this makes it hard for someone with a good memory to actually learn and apply new tools to the exercises. multiple errors within the exercises and some of them were lacking info. aside from that, this was a great basic course to learn one example of each of the most common functions used within SQL as well as main definitions.

Terrible. The instructions are incomplete. When uploading the sql scripts there are errors, when trying to talk to someone you get the TAbot who can only say Hmm lets talk about something else. I am surprised how bad this is you would think IBM would know what they are doing.
