This slide overviews a Java-based Splitwise clone that simplifies shared expense management for groups like trips, roommates, friends, and teams. It records expenses, calculates individual shares, tracks debts, and minimizes transactions with optimizations.

Project Overview

• Simplifies shared expense management for groups
• Records expenses and calculates individual shares
• Tracks debts and minimizes transactions
• Applies to trips, roommates, friends, teams
• Java-based Splitwise clone with optimization

Managing shared expenses among groups is difficult, often causing confusion, tracking errors, and incorrect settlements. The objectives are to record group expenses, auto-calculate individual shares, track who owes whom, and minimize settlement transactions.

Problem Statement & Objectives

The proposed solution is a Java-based system for managing group expenses, calculating net balances for settlements, and optimizing transactions to minimize payments. It simplifies tracking who owes whom and supports scenarios like trips, roommates, and teams.

Proposed Solution

• Java-based system manages group expenses
• Calculates net balances for settlements
• Optimizes transactions to minimize payments
• Simplifies tracking who owes whom
• Supports trips, roommates, and teams

The slide "Entities & Relationships" outlines key database relationships in a table format. It details a many-to-many link between User and Group, one-to-many from Group to Expense, and one-to-many from Expense to Split.

Entities & Relationships

{ "headers": [ "Entity", "Relation" ], "rows": [ [ "User ↔ Group", "Many-to-Many" ], [ "Group → Expense", "One-to-Many" ], [ "Expense → Split", "One-to-Many" ] ] }

• Key Entities: Users, Groups, Expenses, Splits, Settlements
• Many-to-Many: Users ↔ Groups via GroupMember
• One-to-Many: Groups → Expenses
• One-to-Many: Expenses → Splits

The slide outlines core logic features like multiple split options (equal, unequal, percentage), accurate net balance tracking, and an algorithm for minimized settlements. It also details the tech stack: Java + Hibernate backend, MySQL database, and JSP/JavaFX frontend for scalable, responsive interfaces.
