Itsc 1213 – Project 1,2 & 3– Bookstore Management System Extended


    ITSC 1213 – Project 2 – Bookstore Management System Extended The main idea behind this activity is to extend Project 1. Create a system that allows a bookstore owner to keep track of their inventory and members utilizing inheritance. In this checkpoint, you will be expanding the previous assignment in two significant ways. This assumes you have a working version of the Bookstore project from the previous assignment. If you were not able to complete that assignment, or if your project had significant issues that affected functionality, please make sure to get in touch with someone on the instructional team to help get your project caught up so you are ready for this one. Recap The same rules apply from Project 1: The owner of a bookstore has asked for your help designing a system that allows them to keep track of the store’s inventory and members. The owner provides you with the following details about what their store currently offers: ● The store sells three types of products: books, CDs, and DVDs. ● The store offers two types of memberships to customers: regular memberships and premium memberships. The regular membership is free, while the premium members pay a fee every month. ● The store keeps track of whether the monthly fee is due or has been paid for their premium members ● The store keeps track of the members and their transactions (number of items purchased, total purchases, ...) regardless if they are regular or premium members. ● The store also keeps track of the inventory of each product. The owner would like to replicate as much of this as possible but understands that software development is an iterative process and we need to start with a small set of features to implement. As as starting point you need to design a system that includes only three distinct functionality. A function, in this context, are abstract ideas like "register a new premium member", or "complete a purchase". While in many programming contexts a specific function refers to what we refer to as methods in Java, here function and method are NOT synonymous. Functions here refer to the holistic application/program/system that we are creating for managing a bookstore. To ITSC 1213 – Project 2 – Bookstore Management System Extended implement your functions it may take one or more methods and will likely involve 1 or more of your classes. One of these functions MUST be to complete a purchase. In order for that to happen the user should be able to select one or more items, and those items should be deducted from the inventory after the purchase is completed. The other two functions are entirely your choice. As you are thinking about these features, think of any application or a website you use to purchase something online. What functionality, you as the user, are able to complete using this application? Answering this question should give you plenty of options to choose from. You are welcome to program or map out additional functions. These do NOT necessarily need to be implemented, but can be included using empty methods (stub methods) to make your system look more complete. Important Considerations ● We want you to take an Object-Oriented approach in this project. That means you will be creating a good number of classes that will all interact with each other, rather than having everything contained within one class and one main method. The FastFoodKitchen lab is a good example of this kind of design. In the same way that the FastFoodKitchen contained a list of BurgerOrders, the Bookstore may contain a list of members, or a list of books that can be purchased. ● It is very important to consider what attributes a book would need, that a member would need, etc. This is especially important when you consider functionalities like purchasing... which of these attributes do you need to access during a purchase, and if you need that information where/how can you find it? Preliminaries I can not iterate the importance of having a working implementation that meets the requirements of programming checkpoint 2. Please refer to this page for a UML diagram and JavaDoc of a possible design and solution overviewed in class. ITSC 1213 – Project 2 – Bookstore Management System Extended While you can use your existing Bookstore project as a starting point for this submission you are encouraged to make a copy, rename it to lastNameFirstNameProject2 and modify that instead. For Project 2 you will be including inheritance including: abstracts, interfaces, overrides, and super calls and adding functionality to your bookstore management system. Part A – Inheritance, Abstraction and Interfaces (10 points) In this part we want to introduce inheritance and abstraction into our system. Update your design to utilize inheritance when representing the different items the store sells. At a minimum your design should incorporate a Product class that is sub-classed into the three different items available for purchasing - books, CDs, and DVDs. The Product class must be an abstract class that implements the Comparable interface. Since we never really need to instantiate objects of the type Product it makes it a good candidate for abstraction. When comparing products we want that to be either based on the price of the product or the amount in stock. Choose one of those attributes and implement the compareTo method to work based on that field. Part B – More Interfaces (10 points) In this part you want to update your Bookstore program to implement the following interface: BookStoreSpecification <> BookStoreSpecification + restockProduct(int, int) : void + inventoryValue() : double Notice that this interface has only two methods: restockProduct (int, int) and inventoryValue(). If you have a Bookstore class this might be a good option to implement this interface. Where you implement this is highly dependent on your project design. You might have a separate inventory management class that might be a better place to implement this interface. You are encouraged to discuss your design with the ITSC 1213 – Project 2 – Bookstore Management System Extended instructional team for feedback on your project design. Keep in mind that with computational problem solving and design there are many ways of achieving a solution. Explore and have fun with it! Part C – Changing the Test Harness (6 points) Update your Test Harness class to include menu options to test the functionality added in Parts A (Comparing products) and B (restock a product and display inventory total). Keep in mind here that you can add helper methods to your class to make the code cleaner and easier to debug. Part D - Coding Style and Documentation (4 points) This grade is awarded for
