E-Business System - IT Assignment

An online device sale company needs to implement an e-business system. The system is a typical 3-tier enterprise application that integrates a presentation tier, a business tier and a persistence tier. After user requirement and budget analysis, the executive of IT Department of the company has decided to use Java EE open source technology and related platforms and tools for the implementation of the system. As an officer of the IT Department of the company, you are delegated as the developer of the system core. To accomplish this task, you will need to design, implement, test and document the e-business system. 1. The persistence tier a. The company sells only 2 products, laptops and smart phones, and may extend to more products in the future through this general framework. A major assumption is that the 2 products share some common properties. For example, both laptops and smart phones have the properties of Brand, Model, Size of Display, Weight, OS, Camera and Wi-Fi etc. However, a laptop has speciality properties such as a Network Interface (e.g. 1000G Ethernet LAN), Hard Drive and Optical Drive etc.; a smart phone has speciality properties such as Cellular Connectivity (e.g. 4G 700/750/800/900/1800/2100), Location (e.g. GPS) and SIM Card (e.g. Nano or Micro)........... Question 1: The diagram of architecture: it should include major components from all 3 tiers, which are depicted by using any formal method e.g. UML. The typical workflow: you need to use an example workflow, e.g. creating a customer’s order, to describe the tier components interaction and JSF pages navigation. The end user manual and test instruction: you are required to provide detailed instructions about how a user would compile and deploy the software and use the software to persist at least 2 products, 2 customers, where each customer puts in at least 2 orders. Question 2: You will have 2 options to provide the complete implementation code of the 3 tiers, including Java source code and executable files, persistence files and JavaServer Faces xhtml pages. You can provide your implementation by either a Maven project or a NetBeans project, which must satisfy: 1. The project can be compiled directly without any further revision/re-development or debugging. 2. The generated .war application from the project can be executed on a separate/independent GlassFish server (not the NetBeans embedded one) to interact with a separate/independent Derby database (not the NetBeans embedded one).
