Introduction The goal of this project assignment is to consolidate the knowledge and skills you learned throughout the course. You will be implementing a Java application for managing a store in two phases. A team of two students will work together on each phase without any external help except from the course instructor or TA. The theme of the store and the content will be chosen by the team. The objective of this first phase of the project is to develop the following skills. Ability to design and implement larger applications using the Object-Oriented Programming (OOP) Paradigm. Use UML class diagrams to design applications. Ability to test and debug applications. Ability to save application data to and load them from stored files. Ability to work in teams. This assignment counts as 10 points of your final grade. The remainder of this document will describe the requirement for this project (Phase 1). Store Name and Contents Your first task is to decide on the type of content you want to sell on the store. This will determine how your items are printed (and displayed in Phase 2), and how your store will be organized. You should explicitly list all item that will be available. In addition, you will need to chose a name for your store. System Specification Your application must support the following features: Allows loading the application data from a file (if the file is not specified load the data from the file ''store.data'') Allows saving the application data from a file (if the file is not specified save to the default file'store.data'") There are three types of users: Managers, Employees, and Customers. All users have an and a name. Managers and Employees need to login with an ID and a password ID . Customers only need their ID to login. All users can perform the following - List store items by category - Search store items by name or price, or any attribute you think is important for your specific store. - log out • In addition, Managers and Employees can perform the following - Add store items - Remove store items Create a new Customer account • Managers can add and remove users (i.e, Managers, Employees, Customer), except themselves If there is no file to load data from, by default the store will have no items and only a single Manager user named "owner" with an ID "1", and a password "owner".
