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....

Great introduction to SQL. But the course forces the learner to be dependent on IBM Cloud

The lectures could be quite challenging to understand due to the technical jargons used.

It can be seen as basic course if you are coming from a relational database background.

IBM Labs using the Cloud are pretty bad. Other than that, great information and course!

All good but more work on nested queries and built in functions will make it better.

It is understandable, but not for the novices. Some assignments could be challenging.

Very easy to understand. Overpriced. I would give 5 stars if it was below 20 dollars.
