Cognos 8 Multitiered Architecture

Tier 1. Web Server – contains one or more Cognos 8 gateways which is the typical source for web communications.

Tier 2. Applications – contains one or more Cognos 8 servers. A server runs requests such as reports, analyses, and queries, that are forwarded by a gateway. Components of Application tier include:

Dispatcher – operates services and routes requests. Content Manager – manages storage of all application data

such as report specifications, security, configurations etc… Tier 3. Data – contains content store and data sources.

Content Store – is a relational db that contains data that Cognos 8 needs to operate such as report specs, published packages, and data source connection information, etc…

Data Sources – relational databases, dimensional cubes, files, or any other physical data stores that can be accessed through Cognos 8.

Framework Manager

• Framework Manager (FM) is the Cognos metadata modeling tool for creating and managing business-related metadata for use in Cognos 8 reporting and analysis.

• Objects you work with within Framework Manager:

• Projects – contains models, packages, data sources, namespaces, and related information for maintaining and sharing model information.

• Model – is the set of related dimensions, query subjects (i.e. tables), and other objects required for one or more reporting applications.

• Namespaces – uniquely identifies an object.

• Package – is a subset of dimensions, query subjects, and other objects defined in a project. A package is what actually gets published to the Cognos portal for reporting and ad hoc querying.

• Query Subject – is a set of query items that have an inherent relationship. They behave like tables in most cases.

• Query Item – is the data element that can be placed on a report.
