The Java Marriage Bureau System is a Java project that combines Data validation and Database schema, built with Maven. 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 Database schema and Maven, 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 Data validation, orchestrated with Maven and Database schema. 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.

Modular Java application around Data validation and Database schema
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 Data validation; the logic layer implements business rules with Maven and Database schema; and the output layer presents results via CRUD operations. Shared validation, storage, and logging modules support all layers, keeping the application robust and easy to extend.

Build the input and model layer with Data validation.
Implement the core business logic using Maven and Database schema.
Add the output and presentation layer via CRUD operations.
Wire up end-to-end flows with validation and error handling.
Write tests, run the application, and refine features.
Package the project, document it, and prepare the demo and viva report.
Build production-style Java applications
Apply Writing SQL queries and Designing DAO layers
Design classes and manage data in Java
