Which action should the business analyst take to meet these requirements?

A business analyst is creating a data model from several Excel files that contain several hundred thousand rows of data.

The requirements include:

• Users need to drill down to various details within the available data set.

• Several final measures will be repeatedly used. These final measures require combining several fields in a single table.

• User experience and load time is a high priority.

Which action should the business analyst take to meet these requirements?

A. Aggregate the data to the source period

B. Develop a master item using the required source fields

C. Combine the various source fields in a calculated item in the Data manager

D. Combine the source fields and create additional fields in Excel

Answer: B

Explanation:

In Qlik Sense, creating Master Items allows business analysts to define fields, dimensions, and measures that are used consistently across the app. This is particularly important for measures that will be used repeatedly. By defining these as master items, you ensure that all calculations are consistent and optimized for user experience and performance. This approach also supports drill-down capabilities while ensuring a responsive user experience. Key Concepts:

Master Items: Master Items are reusable definitions for dimensions, measures, and visualizations. When you create a measure as a Master Item, it becomes available for use across different visualizations, ensuring consistency and reducing duplication of effort.

User Experience and Load Time: Using Master Items optimizes performance, as Qlik Sense caches the results of these items, reducing the need for recalculating complex measures each time they are used.

Why the Other Options Are Less Suitable:

A. Aggregate the data to the source period: While aggregation could reduce the data volume, it would limit the ability to drill down to the detailed levels required by the users.

C. Combine the various source fields in a calculated item in the Data manager: While you could create calculated fields, this method would be less efficient than defining measures in the Master Items library. Calculations done outside Master Items would need to be manually repeated in each visualization, leading to inconsistencies.

D. Combine the source fields and create additional fields in Excel: This would not optimize user

experience or load time, as it relies on modifying source data outside of Qlik Sense and could lead to

unnecessary data duplication and inefficiencies.

Master Items Best Practices: Qlik Sense promotes the use of Master Items for consistent measure definition and reuse, as they improve performance and ensure consistency across multiple visualizations.

By creating a Master Item, the business analyst ensures a streamlined and efficient user experience, making B the best and verified option for this scenario.
