What are the three dimensions that characterize an e-procurement market based on its business functionality? Name two other market characteristics of an e-procurement Net marketplace.

The three dimensions that characterize an e-procurement market based on its business functionality are that 

(1) they are horizontal marketplaces 

(2) in which long-term contractual purchasing agreements are used 

(3) to buy indirect goods. 


Other market characteristics of e-procurement are:-

  • Net marketplaces are that they are independently owned, they are many-to-many markets, and they use fixed-price catalogs.
  • E-procurement companies serve as intermediaries connecting hundreds of online suppliers offering millions of MRO goods to business firms who pay a fee to join the market, thus it is a public marketplace. They are mediated by an independent third party that purports to represent both buyers and sellers; however, they are likely to have a bias in favor of the buyer because they include the catalogs of competing suppliers and competing e-distributors.

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?

Discuss classification or taxonomy of virtualization at different levels.
