E-Tailing

• Business sells retail goods on the internet to
  other businesses/customers.
• Online catalogs of inventory are created to keep
  track of item availability.
• Customer service is available to deal with
  customer questions or complaints. This service is
  provided in a forum setting (via the internet) or
  through e-mail, fax.
• Customer friendly user interface using Soft Cart
  technologies.

EDI (Electronic Data Interchange)

• Standard format for exchanging business data
  between business and client.
• EDI message contains a string of data elements,
  each of which represents a singular fact, such as
  a price, product model number and so forth.
• Customer enters relevant personal data, such as
  address, phone number, email, the item or items
  to be ordered etc. so that business can make a
  record for that particular customer. This way the
  business can not only deliver the customers
  order but can also let the customer know of
  special deals on items, or an item that has just
  been released.

Security Measures

• The Security use case has two main areas
  Encryption and Decryption.
• It begins when the Customer requests access to
  resources, such as the Web pages for registered
  or selected users passwords and member ID.
• When ordering and personal information is
  requested, encryption is used to ensure the
  privacy and effectiveness of the transactions.
• Data bits rearranged into digital signals by
  sophisticated computer algorithms. Needed for
  carrying out sensitive transactions, such as
  credit-card purchases on-line.
• Correct decryption key required to recover
  contents of encrypted signal by converting
  encrypted data back into its original form, so
  that it can be understood

7
Security Measures (cont.)

• System uses SSL (Secure Sockets Layer) which
  manages the security of message transmissions in
  a network.
• Programming for keeping messages confidential
  contained in a program layer between an
  application (customers Web browser) and the
  Internets TCP/IP layers.
• Uses public and private key encryption from RSA
  (an Internet encryption and authentication system)

9
Overview Statement

• The purpose of this project is to create a
  point-of-sale e-commerce system to be used over
  the internet.
• The system should meet the customers demand,
  include the consideration of providing e-commerce
  solutions to other businesses, meet the goals of
  the design team, function as specified and have
  the necessary attributes to do so.

10
Customers

• Customers can be any business or institution that
  requires an e-commerce solution
• Customers needs need to be ascertained so that
  their wishes can be met in the final product. As
  much as possible it is the wish of this business
  to tailor-make the end product to fit the
  customers wishes.

11
System Functions

• The system should perform according to the
  following specifications
• Record the sale items purchased.
• Calculate current sale total, including tax and
  shipping options.
• Reduce inventory quantities when a sale is
  committed.
• Log completed sales.
• Display description and price of item recorded.

12
System Functions (cont.)

• -Handle check payments (electronic checks),
  provided that authorization measures are met.
• Bank Name
• Bank Code
• Checking Account number
• -Handle credit payments, capturing credit
  information from a card reader or manual entry,
  and authorizing payment with the businesss
  credit authorization service via a modem
  connection.
• -Log credit payments to the accounts receivable
  system, since the credit authorization service
  owes the business the payment amount.

13
System Attributes

• The system attributes that this e-commerce
  solution stresses are
• -Response Time
• When customer is placing an order the description
  and price should appear within a reasonable
  amount of time
• -Operating System Platforms
• Currently there are product solutions for most
  viable platforms. Currently those platforms are
  Windows NT, Windows 95, and Windows 98.
• - Fault Tolerance
• Must log authorized credit payments to accounts
  receivable within 24 hours, even if power or
  device failure.

14
Goals

• The goals for this e-commerce solution are as
  follows
• -Automatic inventory control
• -User friendly web page so that customer can
  navigate the page easily to find the product of
  their choosing.
• -Fast and easy order placing.
• -Allow customer feedback
• -Fast and accurate sales analysis
• -Allow global shipping

15
Non-Functional Requirements

• Web pages can be developed using a number of
  different technologies.
• ASP
• ColdFusion
• Java
• JavaScript
• HTML

16
Database Integration

• Our web database integration is based on Active
  Server Pages (ASP). An Active Server Page is an
  HTML document that contains embedded server-side
  scripting. Web servers compatible with ASP can
  execute these server-side scripts. On the client
  side, an ASP is a standard HTML document,
  viewable on any platform using any Web Browser.

17
Abstract System Model

• How the e-system sends messages to complete the
  virtual shopping transaction. The customer
  enters their information and the information is
  stored and entered into the customer database
  when the transaction is complete.

User Interface Design

• The external actor (customer) interacts with the
  system and the system reacts to these
  interactions. This sequence diagram shows a
  particular scenario of the e-commerce use case.

19
Architectural Design

• This class diagram illustrates the specifications
  for software classes and interfaces in the
  e-commerce application. Moreover, the class
  diagram provides the software design
  specifications, which define the classes needed
  for payment authorization.

20
System Attributes

• An illustration of the e-commerce solutions
  ability to give the customer the same
  face-to-face interactive ability a store
  provides.
