About OYELEYE

Matthew Oyeleye, I am a data analyst and SQL instructor with real-world experience turning complex data into insights. I teach practical, industry-relevant database skills, focusing on clarity, best practices, and confidence so you can apply SQL effectively in real projects.

About the lesson

These lessons provide a structured and practical journey through SQL and database management. They begin with querying fundamentals, teaching how to retrieve, filter, and summarize data accurately. The course then explains how data is related using relational databases, keys, joins, and entity relationship diagrams, ensuring proper connections between tables. Design concepts emphasize normalization, schemas, data types, and constraints, helping build efficient and reliable databases. Writing lessons focus on creating, updating, and deleting records while enforcing integrity through constraints and triggers. Viewing introduces views and common table expressions to simplify complex queries and improve security. Optimization lessons highlight indexes, transactions, and ACID principles for performance and reliability. Finally, scaling covers advanced database systems, concurrency, replication, and security practices, equipping learners with skills to build scalable, secure, and production-ready database solutions.
