The Java Airline Database App is a Java project that combines Database schema and Query builder, built with Java 17+. The project follows a clean, modular architecture where input handling, business logic, and presentation stay separated, making it easy to test, extend, and present. It showcases practical Java techniques while producing a working, demo-ready application.
Manual and paper based methods for this task are slow, error-prone, and hard to manage. Without a Java application built on Query builder and Java 17+, users cannot process, store, and manage data efficiently, and there is no reliable, reusable way to run the workflow.
This project applies Java techniques through Database schema, orchestrated with Java 17+ and Query builder. The application is designed for correctness and usability, with clean data flow, validation, and error handling. It produces consistent, reusable results and can be adapted to related tasks with minimal changes.
Java 17+

JDBC
Modular Java application around Database schema and Query builder
Configurable settings and validation rules
Clear logging, error handling, and reporting
Clean interface for user interaction
Reusable components for related features
Unit testing and maintainable code
The project is layered: the input layer handles user interaction through Database schema; the logic layer implements business rules with Java 17+ and Query builder; and the output layer presents results via Transaction handling. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.
