Document and Report Generation – including transaction documents, transaction listings and error reports
Inquiry Processing – making inquiries and receiving responses concerning the results of transaction processing activities

12. Main Issues in E-Business Systems
Cross functions Information systems integration (Enterprise Application Integration a.k.a EAI)
Work collaboration between different functions, groups, teams, vendors, and customers

13. Enterprise Application Integration (EAI)
Definition:
