B2BEDI Runtime Topology
VAN Value Added Network A VAN is a networking
service that leases communication lines to
subscribers and adds extra services or
capability such as security, error detection,
guaranteed message delivery, and a message
buffer.
6
B2BEDI Drawbacks

• Very expensive technology
• Requires special networks
• Limited to large companies
• Implicit structure
• Intended for machines only

7
B2BEDI The Best of EDI

• Secure, one-to-one transactions
• End to end real-time transactions

• Warum ist XML wichtig ?

10
Warum ist XML wichtig

• Daten-Identifikation
• XML beschreibt Daten. Nicht die Darstellung der
  Daten. Model View Trennung.
• Verschiedene Applikationen benutzen dieselben
  Daten. Durch Identifizierung der Daten werden
  Daten in verschiedenste Art und Weise
  verartbeitet.
• Daten-Visualisierung mit XSL
• lttogtyou_at_yourAddress.comlt/togt
• Start a new line.
• Display "To" in bold, followed by a space
• Display the destination data.
• To you_at_yourAddress
• Diese Flexibilitaet garantiert "future-proofing"
  der Information.

11
Warum ist XML wichtig

• Inline Reusabiliy
• XML Dokumente können mittels andere Entitäten
  (XML Dokumenten) zusammengesetzt werden.
• XML Dokumente können in line in andere
  Dokumente eingefügt werden.
• Modularisierung von XML Dokumenten.
• Resultierendes XML Dokument ist ein XML Dokument
  und nicht ein XML Doukment bestehend aus Teilen.
• Easily Processed
• Aufgrund der großen Anzahl von Tools und der
  strengen Syntaxanforderungen (im Gegensatz zu
  html) kann XML leicht verarbeitet werden.
• Hierarchical
• XML Dokumente haben eine hierarchische Struktur.
  Datenverarbeitung einfach in einer hierarchischen
  Struktur.

12
B2BEDI Advantages of XML over EDI

• Explicit structure
• Easier validation
• Can easily use the Internet
• Cheaper to implement
• Can open up electronic commerce to small and
  medium-size businesses (social agenda again)
