Online stored value systems

 Online stored value systems 

  • Online stored value systems allow customers to make instantaneous payments to various merchants contingent on the value they have stored in the system.
  • One of the most prominent examples of an online stored-value system would be PayPal. PayPal works by linking the user’s online account with a credit, debit, or checking account that he/she currently possesses.
  • When a transaction is processed, PayPal automatically debits the user’s account and credits the merchant’s account, without having to transfer any sensitive customer credit information. 
  • Other Examples:- Alert Pay, Web Money, 2Checkout, Google Checkout, Payza, Sage Pay, Dwolla, Open Pay, Go cardless, Net Banx 

                                      OR,

 Online Stored Value Payment System

• Stored value systems are a form of electronic payment technology. 

• They coexist with credit and debit technology and principally target low-value transactions.

• Online stored value systems have very low transaction costs.

• Stored value systems are based on creating a form of electronic value, for example on smart cards or as computer files.

• The value can be bought (withdrawn) anytime.

• Today Stored Value Cards (SVC) are one of the most dynamic and fastest-growing products in the financial industry

• One leading difference between SVC and debit cards is that debit cards are usually issued in the name of the account holders. In contrast, Stored Value Cards are usually anonymous.

• The notion "stored value" means the funds and data which is stored on the card

. • Eg: fare cards, telephone prepaid cards, etc.

                                       OR,

    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.
