About the Course

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....

SQL is useful stuff, and the other courses in this track (data science professional certificate) are great, but this course has way, way too many errors in assignments, workbooks etc. The course material needs a major overhaul to make sure

1. Assignment problems are clearly and unambiguously defined

2. Example syntax actually works in the SQL dialect being used in the notebook

3. When saying stuff like "create table like in week 2 Lab 1, part II", make sure that part 2 of lab 1 in week 2 actually has anything to do with creating tables (it currently does not), etc.

4. When saying "replace the part in angled brackets below with...", make sure there actually is a part in angles brackets below

Etc. etc.;I have wasted a lot of frustrating time trying to figure out stuff that had nothing to do with SQL because of the sheer amount of errors and inaccuracies like this in this course.
