Amazon Sales Analysis SQL Project | Advance SQL Project | Part 4 |#datascience #analyst #sqlpractice

Welcome to *Part 4* of my *Amazon Sales & Operations Analysis using PostgreSQL* project. In this series, I am solving *50+ SQL business questions* using a relational Amazon-style sales database covering customers, orders, order items, products, sellers, payments, shipping, inventory, and more. In Part 4, I’ll continue from where we left off and work through more business questions using concepts such as: • Multi-table JOINs • Subqueries • Date Functions • Filtering and conditional logic • Ranking Functions • Windows Functions • Business-focused SQL analysis The goal is not just to write SQL queries, but to understand the business problem behind each question and use the data to find meaningful answers. This is a multi-part project, so *stay till the end of the series* as the questions gradually become more complex and cover a wider range of SQL techniques. 🔗 *Connect with me on LinkedIn:*   / chitransh-jain-684993252   *Project:* Amazon Sales & Operations Analysis *Tool:* PostgreSQL *Questions:* 50+ *Part:* 4 #SQL #PostgreSQL #DataAnalytics #SQLProject #DataAnalyst #Amazon #SalesAnalysis #BusinessAnalytics #database #businessanalytics #amazon
