EDI layered architecture

 EDI layered architecture

  1. Semantic (or application) layer
  2. Standards translation layer
  3. Packing (or transport) layer
  4. Physical network infrastructure layer



EDI semantic layer:

  • Describes the business application
  • Procurement example
    - Requests for quotes
      - Price quotes
        - Purchase orders
          - Acknowledgments
            - Invoices

            • Specific to company & software used


            EDI Standard layer(Standards translation):

            • Specifies business form structure so that information can be exchanged
            • Two competing standards:- 

            1. The ANSI ASC X12 Standards 

            • The X12 standard defined a set of documents, which are referred to as transaction sets. • The common documents and their corresponding transaction set numbers: 850 P.O, 810 Invoice, 855 P.O. Ack., 856 Ship Notice 

            2. EDIFACT Standards 

            • A combination of the ASC X12 standards and the Trade Data Interchange (TDI) standards developed in the United Kingdom and used throughout Europe.

               

            2) EDI transport layer

            • How the business form is sent, e.g. post, UPS, fax
            • Increasingly, e-mail is the carrier
            • Differentiating EDI from e-mail

            1. Emphasis on automation
            2. EDI has certain legal status


            3) Physical network infrastructure layer

            Dial-up lines, Internet, a value-added network, etc.

            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?

              b) The specific OLAP operations to be performed are: 1. Roll-up on date from date id to year. 2. Roll-up on spectator from spectator id to status. 3. Roll-up on location from location id to location name. 4. Roll-up on the game from game id to all. 5. Dice with status= “students”, location name= “GM Place”, and year=2004

            Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online.
