Application Integration
Organizations often use IBM host systems for online transaction processing (OLTP) that supports real-time, line of business applications. Traditionally, users have relied on terminal emulation programs to gain access to these host applications. However, information technology departments are increasingly deploying solutions that provide a more seamless level of integration between modern intranet services and IBM host data and applications.
Table 10.3 summarizes the services SNA Server supports to integrate desktop clients with host applications and transaction services.
