代码代写｜CSCI 571 HW4 OPTION 1 – PHOTO ALBUM

本次加拿大作业案例是一个在线图书商城应用开发的App代写project

1. Problem Statement

Design and implement an application for an online bookstore (Look Inna Book). This application lets users browse a collection of books that are available in the bookstore. A user can search the bookstore by book name, author name, ISBN, genre, etc.. When a book is selected, information on the author(s), genre, publisher, number of pages, price, etc. can be viewed. A user can select as many books as she likes to be added to the checkout basket. A user needs to be registered in the bookstore to be able to checkout.

When checking out, the user inserts billing and shipping information (can be different than those used in registration), and completes the order. The bookstore has the feature of tracking an order via an order number. A user can use this order number to track where the order is currently. Although shipping is carried out by a third-party shipping service, the online bookstore should have the tracking information available for when the user inquires about an order using the order number. Assume all books are shipped from only one warehouse (no multiple order numbers for multiple books shipped from multiple warehouses). The bookstore owners can add new books to their collections, or remove books from their store. They also need to store information on the publishers of books such as name, address, email address, phone number(s), banking account, etc.. The banking account for publishers is used to transfer a percentage of the sales of books published by these publishers. This percentage is variable and changes from one book to another. The owners should have access to reports that show sales vs. expenditures, sales per genres, sales per author, etc.. The application should also be able to automatically place orders for new books if the remaining quantity is less than a given threshold (e.g., 10 books). This is done by sending an email to the publisher of the limited books to order a number of books equal to how many books were sold in the previous month (you do not have to implement the email sending component).

2. Project Report

You need to submit one report file that contains the following sections. You can add other sections, but the following sections (except Bonus Features) must be in the report:

2.1. Conceptual Design

This section should explain the conceptual design of the database. That is, the ER-diagram of the database for the bookstore and explanation of all the assumptions made in the diagram regarding cardinalities and participation types. Make sure that the assumptions do not contradict with the problem statement in Section 1.

2.2. Reduction to Relation Schemas

Reduce your ER-diagram into relation schemas and list these in this section.

2.3. Normalization of Relation Schemas

Given the problem statement and your design, write the set of functional dependencies that apply to your database. Show that your relation schemas are either in a good normal form (show tests), or if they are not, show how to decompose them into a good normal form (show decomposition work), then show the testing work to make sure that they are in a good normal form.

2.4. Database Schema Diagram

This section should show the final schema diagram for the database of the bookstore. This diagram should be similar to the schema diagram of the university database that we study in this course.

2.5. Implementation

Feel free to use whichever programming language(s) for your application. Your application can be a web-based application, or a desktop application. In this section, you should describe the architecture of your application.

That is, what the modules in your application are and how they interact. You are encouraged to include a diagram of the application’s architecture and explain (in text) scenarios of using the application and the workflow of your application. It is mandatory that you use a relational database to store all your data (e.g., no key-value stores).

Your application should have two different user interfaces: The first is for the users of the application through which the user can browse and buy books. The second is for the bookstore owners/managers through which they can add/remove books, display reports, etc. (more details about the application’s features can be found in Section 1).

Include screenshots of your application’s two interfaces in different scenarios (e.g., checking out, displaying a report, etc.).
