IBM C1000-065 Exam With Confidence Using Practice Dumps

Using Data Sets: To use a Data set as a data source in a report, it needs to be added to a Data Module.

Data Module Integration: Adding the Data set to a Data Module integrates it into the Cognos environment, making it accessible for report development.

Procedure: Developers can create or modify a Data Module to include the Data set, which then becomes available for use in reports.

Reference: The IBM Cognos Analytics V11.1.x documentation explains the process of adding Data sets to Data Modules, enabling their use as data sources in reports.

In IBM Cognos Analytics V11.1.x, dimensional functions should be used in a report's Query calculation when working with a dimensional or dimensionally-modeled data source. Here’s why:

Dimensional Data Sources:

Structure: Dimensional data sources are organized into dimensions, hierarchies, and measures. These structures support advanced analytical capabilities such as drill-down and roll-up.

Dimensional Functions: Functions such asmember,ancestor,children, etc., are specifically designed to navigate and manipulate the hierarchical data structures in dimensional sources.

Query Calculations:

Contextual Calculations: Dimensional functions allow for context-aware calculations, leveraging the inherent structure of the data source. This ensures that calculations respect the dimensional context and hierarchy.

Analytical Depth: Using dimensional functions enables deeper analytical capabilities, such as performing relative date calculations, time series analysis, and hierarchical aggregations.

Dimensional functions are essential for harnessing the full analytical power of dimensionally-modeled data sources.
