Components of Cognos

Here are the important components of the Cognos software:

Cognos Connection

Cognos Connection is a web portal that allows users to access Cognos 10 and its studios. Based on your assigned role, you can use this component to retrieve, view, publish, manage, and organize a company’s reports, scorecards, and agents.

The Administrator also uses Cognos Connection to establish roles and user permissions and to manage the Cognos Connection content.

Cognos Business Insight

Cognos Business Insight allows users to create their own dashboard using any object. All content which the user is permitted to view will be presented as an object. This can be used in your workspace to create a fully personalized dashboard.

Cognos Query Studio

Cognos Query Studio helps business users to get fast answers to business-related queries. It helps organizations to better understand the product, customer, and organizational needs. It also helps them to react quickly and stay ahead of the competition.

Cognos Analysis Studio

Cognos Analysis Studio helps businesses to find and focus on things which are important to the business. It also helps to understand the latest trends, compare data, and assess business performance for multidimensional analysis.

Cognos Business Insight Advanced

Cognos Business Insight Advanced is a newer module included in Cognos 10. It combines Cognos Query Studio and Cognos Analysis Studio, and it offers a robust authoring environment for business users.

Cognos Report Studio

Using the Cognos reporting tool, you can create pixel-perfect reports for your organization. It allows you to create charts, maps, lists, or any other available report type using relational or multidimensional data sources.

Cognos Event Studio

This tool allows you to assign a specific event that sends a notification to the stakeholder in your organization. You can create agents that enable you to define your events and thresholds. When the event occurs or the threshold is reached, the agent sends the notification.

Cognos Metric Studio

Cognos Metric Studio allows you to monitor and analyze business metrics of your organization by building a scorecard environment. It also helps you to establish criteria and then monitor your organization to see how it is responding as changes are made to the criteria.

Types of Cognos

Alongside the studios, Cognos relies on three content-tier components that store and manage published content:

Content Store

It is a set of database tables which are used by the Content Manager to store the application data of Cognos.

Content Manager

The Content Manager helps you to manage the storage and retrieval of report specifications, configuration data, and published packages from the content store database.

Cognos Content Database

Cognos Content Database is a self-contained database server which is used to host the content store database in demo environments when an enterprise DBMS is unavailable.

Cognos BI vs Cognos Analytics: What is the Difference?

Beginners often mix up the two names. Cognos BI is the classic platform (version 10.x and earlier) built around separate studios, while Cognos Analytics (version 11 onward) unifies those studios into one web interface and adds AI-driven features:
