Cognos 10 Architecture
Cognos 10 has a multitier architecture. For description purposes, it can
be separated into three tiers: Web server, applications, and data. The
tiers are based on business function, and are typically separated by
network firewalls. Cognos 10 user interfaces sit above the tiers.

Web Server: Cognos 10 Gateways
The Cognos 10 Web server tier contains one or more Cognos 10 gateways.
Web communication in Cognos 10 is typically through gateways, which
reside on one or more Web servers. A gateway is an extension of a Web
server program that transfers information from the Web server to another
server.
When a Cognos 10 gateway receives a request, it
• encrypts passwords to ensure security
• extracts information needed to submit the request to a Cognos 10 server
• attaches environment variables for the Web server
• adds a default namespace to the request to ensure that the server
authenticates the user in the correct namespace
• passes requests to a Cognos 10 dispatcher for processing

Applications: Cognos 10 Servers
The Cognos 10 applications tier contains one or more Cognos 10 servers.
A Cognos 10 server runs requests, such as reports, analyses, and
queries, that are forwarded by a gateway.
Cognos 10 Servers includes
•Dispatcher
•Content Manager
Dispatcher
The dispatcher starts all Cognos 10 services configured and enabled on a
computer, and routes requests.
Content Manager
Content Manager is the Cognos 10 service that manages the storage of
customer application data, including security, configuration data, models,
metrics, report specifications, and report output. Content Manager is
needed to publish models, retrieve or store report specifications, manage
scheduling information, and manage the Cognos namespace.

IBM Cognos Connection
IBM Cognos Connection is a Web portal provided with IBM Cognos BI, providing a
single access point to the corporate data available for its products. It provides a
single point of entry for querying, analyzing, and organizing data, and for creating
reports, scorecards, and events. Users can run all their Web-based IBM Cognos BI
applications through IBM Cognos Connection.
IBM Cognos Administration
IBM Cognos Administration is a central management interface that contains the
administrative tasks for IBM Cognos BI. It provides easy access to the overall
management of the IBM Cognos environment and is accessible through IBM
Cognos Connection.

Report Studio
Using Report Studio, report authors create, edit, and distribute a wide range of
professional reports. They can also define corporate-standard report templates for
use in Query Studio, and edit and modify reports created in Query Studio or
Analysis Studio.
Analysis Studio
In Analysis Studio, users can explore, analyze, and compare dimensional data.
Analysis Studio provides access to dimensional, OLAP (online analytical
processing), and dimensionally modeled relational data sources.
Event Studio
In Event Studio, you set up agents to monitor your data and perform tasks when
business events or exceptional conditions occur in your data that must be dealt
with. When an event occurs, people are alerted to take action.
