Platform architecture
Enterprise software applications are n-tier, where "n" can represent any number of tiers, or layers of processing. The IBM TRIRIGA Application Platform is a logical four-tier system: web, application (and process), tools, and database.
The layering of an application into logical tiers also separates the functions in each tier. In terms of physical tiers, each physical tier describes the actual hardware configuration, the pieces of equipment, and the function of each piece.
The IBM TRIRIGA Application Platform Compatibility Matrix lists the servers, components, and operating systems on which the IBM TRIRIGA Application Platform is certified.
