Business dashboards communicate complex information quickly. They
translate information from your various corporate systems and data
into visually rich presentations using gauges, maps, charts, and other
graphical elements to show multiple results together.

Cognos 8 Architecture


Cognos 8BI architecture can be separated into three tiers:

Web server

Applications

Data


The tiers are based on business function, and are typically
separated by firewalls


User interfaces sit above the tiers


Zero
-
footprint user interface that uses the default browser
configurations provided by Netscape and Microsoft




Cognos 8 Architecture

Tier 1. Web Server: IBM Cognos 8
Gateways


The IBM Cognos 8 Web server tier contains one or more IBM Cognos 8
gateways.



Web communication in IBM Cognos 8 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.



IBM Cognos 8 supports several types of Web gateways, including




CGI : The default gateway, CGI can be used for all supported Web
servers. However, for enhanced performance or throughput, you may
choose one of the other supported gateway types.




ISAPI


ISAPI can be used for the Microsoft Internet Information Services (IIS) Web
server. It delivers faster performance for IIS.

Tier 1. Web Server: IBM Cognos 8
Gateways



When an IBM Cognos 8 gateway receives a request, it





encrypts passwords to ensure security




extracts information needed to submit the request to an IBM Cognos 8
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

Tier 2. Applications: IBM Cognos 8
Servers



The IBM Cognos 8 applications tier contains one or more IBM Cognos 8
servers.



An IBM Cognos 8 server runs requests, such as reports, analyses, and
queries, that are forwarded by a gateway. An IBM Cognos 8 server also
renders the IBM Cognos Connection and Metric Studio interfaces.



Each IBM Cognos 8 installation includes




Application Tier Components, which include a dispatcher that operates
services and routes requests




Content Manager which manages IBM Cognos 8 information

Tier 3. Data: Content Providers


The IBM Cognos 8 data tier contains the




content store




data sources




metric store



Content Store


The content store is a relational database that contains data that IBM Cognos 8
needs to operate, such as report specifications, published models, and the
packages that contain them; connection information for data sources; information
about the external namespace, and the IBM Cognos namespace itself; and
information about scheduling and bursting reports. The relational database


can be IBM Cognos Content Database or another supported database.



Design models and log files are not stored in the content store.



IBM Cognos 8 includes the IBM Cognos Content Database as a default content
store. You can usethe IBM Cognos Content Database as your content store, or you
can use other databases, such asMicrosoft SQL Server, Oracle, IBM DB2, or Sybase.

Tier 3. Data: Content Providers


Data Sources


Data sources, also known as query databases, are relational databases,
dimensional cubes, files, or other physical data stores that can be accessed
through IBM Cognos 8. Application Tier Components use data source
connections to access data sources.





Metric Store


A metric store is a relational database that contains content for metric packages.
A metric store also contains Metric Studio settings, such as user preferences.


More than one metric store may be created. For example, one metric store may
contain content for a sales application and another metric store may contain
content for a finance application.
