Cognos TM1 Applications architecture
IBM® Cognos® TM1® Applications has a multi-tiered architecture
that consists of three tiers: Web clients, Web application servers,
and data.
The following diagram shows the multi-tiered architecture and basic communication paths for all the Cognos TM1 Applications components.
Figure 1. Cognos TM1 Applications architecture overview
diagram
The lines in the Cognos TM1 Applications architecture diagram are primarily intended to show the typical communication paths required for the tasks managed by the Cognos TM1 Application Server, such as keeping track of workflow states.
In addition to these communication lines, Cognos TM1 Performance Modeler and Cognos Insight also require a direct connection to the underlying Cognos TM1 Server at all times. As an exception, when using Cognos Insight in Distributed mode, it does not require a constant connection to the Cognos TM1 Server.
