Pathway Environment
Through Pathway/iTS and related products, the Pathway environment provides a
client-server model for web-based, terminal-based, and workstation-based
applications. Transactions can be initiated by workstations, terminals, intelligent
devices, and general devices. The optional Pathway/XM product provides enhanced
and simplified system management, increased system capacity, automatic load
balancing, and other features for managing Pathway applications.
If you have investments in 6530 terminals, for example, or if your organization requires
central control of program code, the Pathway environment is the choice for you.
