Data Quality
A Business Data Owner or Director of Data Governance can view the Data Quality Dashboard to evaluate the quality of data and drill down into areas of data quality concern.
The dashboard and charts only allow access to detail data to which the logged in user has access. Refer to Configure User Settings, Reports and Filters for more information about setting up user access.
To use the Data Quality Dashboard:
View Data Quality Dashboard
The overview area of the Data Quality Dashboard displays a doughnut chart with the overall data quality score across all reports as well as charts that show the data quality score for each of the seven industry standard quality dimensions delivered with Data Quality.
Data Quality Dashboard — Initial Overview View
The dashboard filter option (Filter on My Reports) filters the dashboards to show data based on the reports to which the logged in user has access or all reports. A user can only drill-down to view report data to which they have been granted access. Refer to Configure User Settings, Reports and Filters for more information about setting up user access.
Each segment on a chart represents one sigma level. There are seven levels. A fully shaded segment represents the completion of a level, a partially shaded segment represents a partial completion of a level, and a blank segment represents a level not fully or partially completed. The sigma level displays inside the charts if the Enable Sigma Level checkbox is checked on the Data Quality Scoring Threshold section of the Metric Parameters tab on the Parameters page.
The colors of the segments are based on data quality score thresholds, which define the status assigned to an object being scored when the percentage of defects falls below the threshold. Statuses are Red (critical), Yellow (warning) and Green. Refer to Register Data Quality Score Thresholds for more information about status and thresholds.
NOTE: The dashboard is dynamic, as the user clicks options on the dashboard the data displayed is updated according to context. The label above the overall charts and overall scores displays the current context.
