SmartPOS: A Web-Based Point-of-Sale and Inventory Management System

Small retail shops such as mini-marts often record sales and stock manually or in disconnected spreadsheets, which makes it difficult to know current stock levels, track daily sales, or stop a cashier from selling an item that is already out of stock. SmartPOS is a web based Point-of-Sale and Inventory Management System built with Python, Flask, and MySQL that lets an Admin manage products and view sales reports, a Cashier process sales at checkout, and a Customer hold a simple account to view their own purchase history. The system applies Object-Oriented Programming through a layered architecture that separates domain models, business services, and database repositories. Core features include role-based authentication, product and stock management, a sales/checkout workflow that automatically updates inventory, product search, and a sales report page. Given a 5-week development window, the team will build the minimum required features first and treat extras such as discounts and customer accounts as optional stretch goals. The expected output is a working Flask application backed by a MySQL database, supported by test cases and a live demonstration of a full sale transaction.

FitTrack — Web-Based Gym Management, From Member Sign-Up to Self-Service

Many gyms still manage member information, memberships, attendance, and trainer scheduling using paper records or disconnected spreadsheets. This slows down daily operations, increases the chance of data-entry errors, and makes it difficult for staff to quickly check a member's status or history. This proposal presents the design of the Gym Management System (GMS), a web-based application built with Python, Flask, and MySQL that centralizes member registration, online membership purchase, attendance logging, trainer-session booking, and payment tracking within a single role-based platform. Visitors can browse membership plans and trainers freely; creating an account is only required to purchase a membership or request a trainer. The system supports four roles (Administrator, Staff, Trainer, and Member) each governed by a role-and-permission model that restricts every user to the features relevant to their responsibilities. Members log in to their own self-service dashboard to view their current membership plan and expiry date, their assigned trainer, their attendance history, and the total amount they have spent on membership and trainer sessions. The application is built on a three-layer object-oriented architecture (Domain Models, Service Layer, and Repository Layer) on top of a normalized MySQL database, keeping the codebase testable, maintainable, and easy to extend. This document sets out the problem the system addresses, its objectives and scope, its target users and stakeholders, its proposed features, its object-oriented and database design, and the timeline the team will follow to deliver it.

Gym Membership management System

Many small and medium-sized gyms still manage members using paper forms, spreadsheets, and manual payment records. These methods can take time, cause data entry mistakes, and make it difficult for staff to know whether a member is active or has expired. This project proposes a Gym Membership Management System to make these tasks easier and more organized. The system will be a web application developed using Python, Flask, and MySQL, with Object-Oriented Programming principles. It will provide separate access for Admin, Staff, Trainer, and Member users. Admin and Staff can manage members, membership plans, payments, and attendance. Trainers can view assigned members and training sessions, while Members can view their own membership, payment, and attendance information. The system will also provide search, filtering, expiry status, and simple reports such as daily revenue and membership status. The application will use a four-layer structure: Model, Repository, Service, and Route. Development will follow five two-week sprints, with testing performed during development. The expected result is a working prototype that reduces manual work, keeps records organized, improves membership checking, and provides a clear way to manage gym information in one system.

ADVANCED OOP — R&D PROJECT PROPOSAL INTERACTIVE QUIZ ENGINE

This research and development project proposal presents the design, architecture, and implementation strategy for the Interactive Quiz Engine, a web-based educational assessment platform built with Python, Flask, and MySQL. Educational institutions frequently suffer from feedback delays caused by manual test grading, non-reusable assessment materials, and fragmented student tracking across spreadsheets and paper records. The Interactive Quiz Engine directly addresses these inefficiencies by introducing a multi-format quiz creation tool, automated evaluation pipelines for objective question types, and centralized attempt history tracking. By leveraging core Object-Oriented Programming (OOP) principles—specifically polymorphism, encapsulation, and layered repository design—the engine cleanly separates core business logic (e.g., dynamic answer evaluation) from data persistence and interface routing. The software enables educators to author quizzes containing Multiple Choice (MCQ), True/False, and Short Answer questions within minutes, while providing students with instant score feedback upon submission. Expected project outcomes include a operational 5-layered Flask/MySQL web application, complete automated test suites, dynamic class performance reporting, and comprehensive architectural documentation suitable for academic defense.

Vehicle Inventory and Sales Management System for SMEs

Small and Medium Enterprises (SMEs) that sell vehicles need an effective way to manage vehicle inventory and sales records. Some businesses may use manual records, spreadsheets, or separate files to manage their daily operations. This can make it difficult to track available and sold vehicles, record stock movements, manage sales, and retrieve important information. This project proposes the development of a web-based Vehicle Inventory and Sales Management System for SMEs. The system will help users manage vehicle inventory, stock movements, customers, sales, and invoices in one centralized system. It will also include Role-Based Access Control (RBAC) to control user access based on their roles. The system will be developed using Python and Flask, with MySQL as the database. Object-Oriented Programming principles will be applied by organizing the system into domain models, services, repositories, and routes. The expected result is a functional and well-organized web-based system that helps SMEs manage vehicle inventory and sales operations more efficiently.

Design and Development of Retail POS and Inventory Management System Using PyQt6 and SQLite3

Small retail businesses often face difficulties in managing products, inventory, sales transactions, and sales records efficiently when using manual or paper-based methods. These methods may result in inaccurate inventory records, calculation errors, and difficulties in tracking sales information. This project aims to design and develop a desktop-based Retail Point of Sale (POS) and Inventory Management System to improve the management of retail operations. The system is developed using PyQt6 for the graphical user interface and SQLite3 for local database management. The Research and Development (R&D) approach is applied to identify system requirements, design the system architecture and database, develop the user interface and core functions, and plan system testing. The proposed system includes product management, inventory management, sales transactions, search functionality, stock monitoring, tax and discount calculation, and sales reporting. The system is expected to provide a simple and efficient solution for managing retail products, inventory, and sales while reducing manual work and improving data accuracy.
