Materials and Preparation This section provides the materials and preparation tasks that you need to teach this module. Required Materials To teach this module, you need the following materials:  Microsoft ® PowerPoint ® file 2260A_02.ppt  Module 2, “Examining E-Business Applications”  Lab 2.1, “Examining a .NET B2C Application”  Lab 2.2, “Examining a .NET B2B Application” Preparation Tasks To prepare for this module, you should:  Read all of the materials for this module.  Complete the labs. Presentation: 40 Minutes Labs: 30 Minutes iv Module 2: Examining E-Business Applications Module Strategy Use the following strategy to present this module:  Functional Characteristics of B2C Applications Provide an overview of B2C e-commerce. Focus on the functionality required for a B2C application, and do not delve into the details of the Microsoft .NET technologies that can be used to achieve the required functionality. These details are provided in the later modules. Be aware that because the students are users of the Internet, they are likely to already be familiar with B2C Web sites, even if they have not developed one of their own.  Lab 2.1: Examining a .NET B2C Application In this lab, students will navigate the IBuySpy application, which is a fictitious retailer Web site that sells spy equipment. Students will explore how the site implements some key requirements of B2C applications. Students will also test the basic functionality of the B2C features of this application.  Functional Characteristics of B2B Applications It is less likely that students have exposure to B2B e-commerce. However, you must not discount the possibility that some of the students may have already worked on such sites. You must gauge the levels of exposure to B2B e-commerce that the students have had and then tailor your presentation accordingly. Emphasize how B2B e-commerce automates data processing that has traditionally been expensive and time consuming. The topics on both the paper-based and automated procurement processes will help explain what B2B e-commerce is about.  Lab 2.2, “Examining a .NET B2B Application” In this lab, students will explore the B2B procurement solution for a fictitious company named Litware Books. Students will explore how the site implements some key requirements of the B2B procurement solution. The students will also test the basic B2B functionality of the solution. In the labs of the later modules, students will develop a similar automated B2B procurement solution.  Non-Functional Characteristics of E-Business Applications Explain the non-functional characteristics of an e-business application. Tell the students that this section applies to both B2C and B2B e-commerce applications. The focus of this section is on the non-functional characteristics that must be in place before any functional features, such as order processing, can be considered successfully implemented. Module 2: Examining E-Business Applications 1 Overview  Functional Characteristics of B2C Applications  Functional Characteristics of B2B Applications  Non-Functional Characteristics of E-Business Applications *****************************I LLEGAL FOR N ON -T RAINER U SE ***************************** Business-to-consumer (B2C) Web sites are recognized as extremely useful portals to commercial organizations' offerings. There are distinct commercial advantages for companies in selling their products and services to customers through the Internet. If a company does not embrace online trading to improve their sales effort, it will soon become uncompetitive, and they may ultimately lose all of their business. Business-to-business (B2B) sites are recognized as useful tools for increasing the efficiency of communication with trading partners, such as suppliers or related service providers. As with the B2C sites, B2B applications can dramatically improve the operating efficiency of a commercial organization. This module examines the functional characteristics of a B2C application. It then explores B2B applications and describes the type of functionality that can be incorporated into this type of solution. Finally, the module describes the non- functional characteristics of e-business applications. After completing this module, you will be able to:  Identify the functional characteristics of B2C e-commerce applications.  Identify the functional characteristics of B2B e-commerce applications.  Identify the non-functional characteristics of e-business applications. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about B2C and B2B e-commerce applications. 2 Module 2: Examining E-Business Applications Functional Characteristics of B2C Applications  Primary goal of B2C applications is to provide an interesting and easy–to-use experience for customers  A B2C site should support the following characteristics:  Product catalogs for presenting information  Shopping carts to allow customers to store products they intend to buy  Order processing to allow customers to purchase products by placing orders *****************************I LLEGAL FOR N ON -T RAINER U SE ***************************** The primary goal of B2C applications is to provide an interesting and easy-to- use experience for your customer while also providing a valuable point of sale for your company. This will involve allowing the online purchase of your company’s offerings and may include other features that your company can profit from, such as targeted advertising campaigns. Most well-designed B2C sites present information about their products, allow the user to add products to the list of what they want to buy, and then allow checkout as the final step in the purchase process. Product Catalogs A key component of your B2C e-commerce application is presenting information about your products to the potential customer in a professional and attractive manner. Presenting product catalogs and allowing those catalogs to be searched are very common operations for a sales-oriented site. The aim of providing searchable catalogs is to make it easy for a customer to find and purchase products. How a product catalog is stored will have an impact on its performance. For example, if the catalog is managed by a relational database management system (RDBMS), such as Microsoft ® SQL Server ™ 2000, indexes can be created to speed up searches. You must plan your search features carefully at the beginning of the project. Some issues to be considered with respect to product catalogs are:  If a catalog is on a database server, the database can be optimized for certain common types of searches, and the expected load of searching must be considered in the design phase.  If the data to be searched comes from many different sources, performance, availability, and reliability of those sources must also be considered. Topic Objective To explain the functional characteristics of B2C applications. Lead-in The primary goal of B2C applications is to provide an interesting and easy-to-use experience for your customer. Module 2: Examining E-Business Applications 3 Shopping Cart Users expect to be able to store items they intend to buy in some sort of virtual shopping cart. The characteristics of this shopping cart can have a significant effect on the architecture of a site. Even if the state (contents) of the shopping cart is not persistent, there are some tradeoffs involved in the shopping cart implementation used, such as being able to load balance across multiple Web servers while retaining the information contained in a shopping cart. Designing the shopping cart features is covered in Module 4, “Designing the Client Experience,” and Module 5, “Managing the Business Logic Layer,” in Course 2260A, Designing E-Business Applications with Microsoft .NET Enterprise Servers. Order Processing Placing an order is an important activity for most sales-oriented Web sites. This activity could involve many different operations combined into one transaction, such as:  Business logic to confirm available inventory and calculate shipping cost.  Interoperation with other systems to charge a credit card and notify the fulfillment center.  Data access to record the order and update the inventory count. Business requirements, such as the frequency and complexity of transactions desired, will have an impact on the implementation of the transaction- processing system. The details on how to handle transaction processing are covered in Module 6, “Transaction Processing on the Business Logic Layer,” in Course 2260A, Designing E-Business Applications with Microsoft .NET Enterprise Servers.
