Qlik Trust Score™

The Qlik Trust Score™ helps you answer the question "How trustable is my dataset?". This global quality indicator aggregates several metrics into a single and easy-to-understand score.

The Qlik Trust Score™ can be tailored according to the data quality needs of your company, and give you visibility on the healthiness of any dataset.

Overview

From a dataset overview, you can find the Qlik Trust Score™, and comprehensive insights such as:

• The global Qlik Trust Score™ for the selected datasets and a percentage or 5-point rating indicating their healthiness.

• The different factors that can raise or lower the Qlik Trust Score™ of a dataset. They are regrouped under these main dimensions:

  • Validity, that assesses the quality of the dataset itself, including the use of semantic types and validation rules, and reflects the proportion of valid values across the dataset sample. Empty values are not considered as valid in the calculation of this dimension.

  • Completeness, that depends on the number of empty records in the dataset sample.

  • Discoverability, that measures how easily users can find and understand your dataset through its metadata, directly impacting adoption rates.

    It takes into account the fact that this dataset is referenced in activated data products, and reflects how well-documented your dataset is. A well-documented dataset uses proper metadata such as descriptions or tags, both on the dataset itself and on the dataset fields.

  • Usage, that shows how much your dataset is used across dependencies such as Analytics apps, data preparations, data flows, etc. It also takes into account the number of views these dependencies have.

To be able to see the Qlik Trust Score™ of your dataset, you need to have computed the data quality at least once.

Configuring the Qlik Trust Score™

From the Qlik Trust score™ page, you can configure and customize the weight of each dimension used to calculate the Qlik Trust Score™, as well as the display format. Note that this configuration will be applied to all existing datasets of your tenant.

Before configuring the Qlik Trust Score™, make sure that data quality is supported for your tenant. The same features and limitations that apply to data quality also apply to the Qlik Trust Score™, such as the supported file types. For more information, see Data quality for connection-based datasets and Data quality for file-based datasets.

1. In Qlik Talend Data Integration > Data quality, click Qlik Trust score™.

2. To activate or deactivate a dimension, click the toggle on its left.

   The Validity and Completeness cannot be deactivated as they are the most essential parameters to determine the Qlik Trust Score™.

3. To adjust the weight of each dimension, click the plus and minus signs on its right.

   The total of percentages of all dimensions must equal 100%.

4. To customize the display of the Qlik Trust Score™, select either A score out of 5, or A percentage depending on the display format you want.
