PracticeSystemJAVA

Desktop Customer Management System developed with Java.

PracticeSystemJAVA is a desktop application created to practice and demonstrate the development of enterprise applications using Java. The project follows good software engineering practices, combining graphical interfaces, database integration, authentication, data persistence, reporting, backup management, and version control.

The objective is not only to build a functional application, but also to apply concepts commonly found in real-world business systems.
