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....

Lots of good material. Much of it is a commercial for IBM. Directions for operating within the IBM data structure is outdated.

Feels like lectures are being give by an AI instead of an actual teacher. Also some things get repeated in several videos.

The first course I have encountered with lots of labs that make you research and engage more with the course material.

For non-programmers or people with no computer background, it is a bit difficult to comprehend. But overall it is OK.

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.
