Migrating from C/S to Web development

• Redesign of interaction dialog
• Layout of user interface labor intensive
• Complex dialog flow structure
• Only primary windows used
• Design simple user interfaces
• No server changes necessary

Migrating from CG51 WCE to CG60 eBiz

• Easy model conversion
• Small client side modifications necessary
• Problems with radio buttons and IE5.0
• UI redesign because of changes in field sizes
• Changed TIREVENT behavior

Coffee break between transactions?

  proxy servers and browser
• Dynamic content (data) is inserted into static
