Description of Electronic Commerce Framework/Generic Framework of E-commerce.

 Electronic Commerce Framework

  • E-Commerce applications will be built on the existing technology infrastructure
  • A myriad of computers Communication networks Communication software
  • Common business services for facilitating the buying and selling process
  • Messaging & information distribution as a means of sending and retrieving information
  • Multimedia content & network publishing, for creating a product & a means to communicate about it
  • The information superhighway- the very foundation-for providing the highway system along which all e-commerce must travel
  • The two pillars supporting all e-commerce applications & infrastructure
  • Any successful e-commerce will require the I-way infrastructure in the same way that regular commerce needs
  • I-way will be a mesh of interconnected data highways of many forms: Telephone, wires, cable TV wire, and Radio-based wireless-cellular & satellite
  • Movies=video + audio
  • Digital games=music + video + software
  • Electronic books=text + data + graphics + music + photographs + video
  • In the electronic ‘highway system’ multimedia content is stored in the form of electronic documents
  • These are often digitized
  • On the I-way messaging software fulfills the role, in any no. of forms: e-mail, EDI, or point-to-point file transfers
  • Encryption & authentication methods to ensure security
  • Electronic payment schemes developed to handle complex transactions
  • These logistics issues are difficult in long-established transportation

Discuss classification or taxonomy of virtualization at different levels.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?
