Data Flow Comparison for ESP / Citrix / Web-based System
ESP (Internet-based System)
The communication path is direct - from workstation to data server and back.
Citrix System
The Citrix MetaFrame system uses Citrix Independent Computing Architecture,
which enables client devices to shift application processing to the server. In a
Microsoft Windows 2000 environment, this is done by grouping multiple servers
into a 'server farm'. This system requires extremely high processing power in order
to process scores of commands from multi-users at the same time. This impacts
on the cost and the number of users allowed in the system, and hence the size of the
ERP customer.
Web-based System
This system costs less than the Citrix system, but is less scalable. As can be seen,
the communication path is also more complicated than the Internet-based system.
