Intro to SQL – ALX Learning Project
Intro to SQL – ALX Learning Project
Project Overview
Gained hands-on experience with SQL through the ALX Software Engineering program. Learned how to create and manage databases, define table schemas, insert and update data, and query databases using SELECT, JOIN, and other core SQL commands. The project covers data definition, data manipulation, and relational database principles in depth.
- Understanding relational database concepts
- Designing efficient database schemas
- Writing complex SQL queries with JOINs
- Implementing database constraints and relationships
- Created comprehensive entity-relationship diagrams
- Implemented normalized database designs
- Developed complex queries with multiple JOINs and subqueries
- Used foreign keys and constraints for data integrity
