This repository is a learning resource for MyBatis, a popular tool that makes it easier for Java developers to work with databases. Instead of writing SQL queries by hand scattered throughout your code, MyBatis lets you define those queries in configuration files and then call them cleanly from Java, keeping your code organized and your database logic separate. The repo contains two study projects. The first one teaches MyBatis basics through a realistic example: an order and product system built with MyBatis, SpringMVC (a web framework), and MySQL. This hands-on approach helps you see how MyBatis actually works in context rather than just learning theory. The second project goes deeper by revisiting MyBatis concepts using Oracle databases instead, since the author was using Oracle in their real work. You'd want to use this if you're a Java developer learning how to interact with databases more effectively. Rather than writing raw SQL scattered throughout your application or struggling with complex object-to-database mapping, MyBatis provides a cleaner middle ground. It's useful if you're building web applications that need to store and retrieve data, whether you're using MySQL or Oracle. The repository includes actual database setup scripts and detailed notes from the author's learning process, which can help you understand not just the "what" but the "why" behind MyBatis design choices. The README itself points to the official MyBatis documentation and the author's own study notes for the deeper details. This is fundamentally a personal learning journal shared publicly, so it's most valuable as a supplement to official docs if you learn well from seeing someone else's real project examples.
