Components of e-business Business relationship Based on personal contact Expressed as an agreement (prices, delivery terms) Business transactions Order, Invoice, Price list, etc. Information By mail, fax, telephone, …

Business transactions rarely come alone a payment refers to an invoice which refers to a delivery advice which refers to an order confirmation which refers to an order which refers to a price list which..... The same information is involved from ”cradle to grave” Scenarios

Goals of EDI To get essential data into your business partner’s computer system without manual intervention of e-Business To improve and simplify a business relationship using EDI

Goal of EDI To get structured data from the sender’s system to the receiver’s system Timely Reliably Unambiguously 2009-03-24EDI/BizTalk21

Structured data - 1 “Line number”, “Item number”, “Quantity” 1, 1234, 99 2, 5678, 50 … All records the same 2009-03-24EDI/BizTalk22
23
Structured data - 2 HEAD ONUM ABC123 DATE 090324 LINE 1 ITEM 1234 QUAN 99 LINE 2 ITEM 5678 QUAN 50 DONE 2009-03-24EDI/BizTalk23 This method was used extensively in early EDI. It is flexible, but takes a lot of space (2400 bits/s was fast in those days!)
24
Structured data - 3 ABC123 090324 1 1234 99 2 5678 50 2009-03-24EDI/BizTalk24 This is where we are heading. It is flexible, but takes even more space (1 Mbit/s is slow today)

EDIFACT messages UNH+9876+ORDERS:D:97A:UN:EAN007’ First there was INVOIC Today there are dozens of UNSMs They are too complicated to use directly So subsets are used 2009-03-24EDI/BizTalk28 Message number Message type UNSM Catalogue ID Implementation subset

EDIFACT syntax summary An Interchange consists of one or more Messages which are made up of Segments with a Tag and one or more Simple data elements or Composite data elements with Component data elements all kept in place with Separators and full of Codes 2009-03-24EDI/BizTalk30
31
The Tower of Babel EDIFACT One language...... Many dialects UN/EDIFACT One standard...... Many interpretations
32
GS1’s role For e-Business to work we need to agree Scenarios Transactions Information Semantics Documents Communication …
33
GS1’s role GS1 has developed Standard identifiers (items, places, shipments, …) Standard scenarios (FMCG, Public procurement, …) Standard semantics (Global Data Dictionary) Standard EDIFACT subset (EANCOM) Standard XML messages …
34
Plug-and-pray So what’s the hold-up? EDI standards work between actors But for e-Business to work, the data and processes have to be well-organized inside the firewall That’s where integration software helps 2009-03-24EDI/BizTalk34
35
Conclusion EDI is a comparatively simple IT exercise it gets rid of paper and makes the information flow more efficient e-Business is a management technique that still really has not caught on but only e-Business will bring dividends
