The goal of sentiment analysis is to determine the mood of customer’s feedback/customer support ticket – are they happy, neutral or angry and we need to help them asap. Companies use sentiment analysis to prioritize their customer support queues or user feedback (to deal with negative ones first).

This data warehouse is inspired by an E-commerce website like Amazon.

Our E-commerce website allows vendors to sell items in multiple categories. Users can add as many items as they want to a cart and then purchase a cart with/without a discount code. Users also can return items and leave reviews.

Hi, it’s Anatoli, the author of SQL Habit.

SQL Habit is a course (or, as some of the students say, “business simulator”). It’s based on a story of a fictional startup called Bindle. You’ll play a role of their Data Analyst and solve real-life challenges from Business, Marketing, and Product Management.

SQL Habit is also a collection of Practice exercises (you’re looking at one atm) based on various datasets (E-commerce, Finance, etc). They’re meant to deepen your SQL and Data Analysis knowledge , prepare you for any challenge at work or a job interview.
