Cognos

Product Details

Cognos allows us to visualize and analyze data. To do this, we must import structured data into the tool. The data can be modeled as cubes, dimensions and measures.

A cube is a collection of all of our data and contains a set of dimensions.

A dimension is a single category of data. For example, if we consider a database table that contains columns A, B and C then the table can be thought of as the cube and the columns called A, B and C as dimensions. However, this is too simple a model and Cognos has deeper considerations than just this.

Information Sources

Installation

Work Space development

A Cognos workspace is saved in a CDD file.

When you launch Cognos Insight, the development environment is presented to you:

Next, in order to do something, we need to import some data. We can perform that task from the "Get Data > Import Data…" menu item. This opens an import wizard:

From here we can identify the source of our data.

When we model a cube, we get to define the logical dimensions and measures. From there, we can map the physical data to those logical entities.

Connecting to DB2

An ODBC driver for DB2 is required.
