Editor's Notes

  1. A volte si usa (impropriamente) e-business per indicare e-commerce
  2. On-line delivery of digital content: consegna on-line di prodotti digitali (es. un libro in formato .pdf, un video mpeg etc.) Electronic fund transfer: operazioni bancarie (trasferimento soldi) Electronic share trading: operazioni di borsa (acquisto di quote, azioni, etc)
  3. EDI e EFT erano fatte soprattutto per le aziende Internet permette a tutti di condurre affari elettronicamente
  4. Retail sale = vendita al dettaglio( caratterizzato dall’acquisto diretto di prodotti o servizi dell’attività da parte del consumatore) Automalll.com un sito che consente ai propri utenti discegliersi comodamente da casa il colore dell’ automobile,gli accessori dell’automobile,i pezzi di ricambio Cybermalls = centri commerciali virtuali
  5. Turnover = volume di affari
  6. Prezzi ridotti non solo per la riduzione della manodopera ,ma anche se uno aveva la rete privata tipo edi il passaggio a internet ha dimiuito le spese di manutenzione della rete .
  7. Le società intermediarie devono trovare altri flussi di entrate non tradizionali che possono essere una piccola tassa sul servizio o una pubblicità o combinazioni di entrambe le cose
  8. Le richieste di fornitura vengono pubblicizzate su internet e le imprese possono rispondere per via elettronica
  9. Bisogna tenere conto del fatto che chi usa le interfacce non è un esperto di informatica
  10. Middle-tier risiede la business logic
  11. EJB permette di realizzare i servizi necessari e la logica di applicazione in maniera distribuita Microsoft Commerce Server nel Business Logic usa COM+
  12. Dati su applicazioni di divertimento (la più grossa fetta di mercato)
  13. Servizi bancari forniti in Mobile (dati fino al 2002, previsioni fino al 2006)
  14. 1.9% è un dato irrisorio Si riferisce al secondo quadrimestre del 2000
  15. Usando HTTP non si può tenere traccia dello stato di una certa operazione Per questo motivo c’è bisogno di un servizio di session management Esempio: per tenere traccia del contenuto del carrello
  16. Connessione al database è un’operazione lunga il caching di una connessione velocizza l’applicazione
