Application Tier Components

Application tier components provide the server functionality for processing and routing user requests through IBM® Cognos® Controller server.

Controller Web Services Server

Controller Web Services Server handles requests for activities within IBM Cognos Controller, such as working with accounts, consolidations, companies, and dimensions. Controller Web Services Server also manages data source connections and security information, as well as preparing data in the IBM Cognos Controller database for reports.

Depending on how you have configured security, the Web Services Server may access other components before processing requests, such as authenticating users.

A COM+ application is created when the Web Services Server is installed. This application runs within the Microsoft component services and provides most of the IBM Cognos Controller business logic, such as retrieving report templates and preparing data in the Controller database for reports.
