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 course! Gives a Solid Foundation. But would have enjoyed it even more if it was more intense and challenging.

Not a bad course. Not real intense. Sometimes instructions are hard to follow but good for a casual learner.

La herramienta de trabajo de DB2 es lenta y poco amigable.

No me sentí cómodo usando las consultas en Jupyter

Cognitive labs is a good platform, but it is very unstable, making progress in the course longer and slower.

Good course material - would suggest finding a more viable solution to grading assignments than peer-review.
