## 8 Week SQL Challenge - https://8weeksqlchallenge.com/

SQL Case studies done by Gino Hobayan

Getting better at SQL, one line of code at a time.




This SQL Challenge is an excellent way to apply all the theoretical SQL knowledge I learned from DataCamp's SQL Fundamentals and the Google Data Analytics Certificate.




I used the following: 




- **Microsoft SQL Server** for Case Study #1 - Danny's Diner and #2 - Pizza Runner

- **PostgreSQL (Using DB fiddle)** for Case Study #7 - Balanced Tree Clothing Co. 






# **1.) Danny's Diner**

### **PDF 👉 https://drive.google.com/file/d/1jLHWro41mbfpemUymKv97JmIPyvwgbmz/view?usp=sharing**



**This case study really helped me deepen my understanding of Aggregate functions, Window functions, CASE statements, CTEs, and more.**






# **2.) Pizza Runner**

### **Link to my Solution 👉 https://github.com/Gino-Freud-Hobayan/8WeekSQL_Challenge/tree/main/2.)%20Pizza%20Runner**



Got to practice more Data cleaning and SQL queries.




Currently a work in progress.






# **7.) Balanced Tree Clothing Co.**

**Just tried this case study since it looked interesting.**
