Data Coverage Process

Data Coverage Process

Create a data coverage task to analyze the data in a
data set
. You can edit the parameters used in the analysis. Based on the results, you can choose to move data values across ranges or groups.
The following image shows the tasks that you perform to create a data coverage task and the tasks that you can perform in the task:
The image shows the tasks that you peform to create a data coverage task and the tasks that you can perform to analyze the data.
You can perform the following tasks in a data coverage task that you run:
Create columns to use in the data coverage analysis
Create columns that map to source data columns to use in the analysis. You can create columns that use source data as is or in ranges of data values. You can also create columns that map data values across specific groups of values.
Run the data coverage task and view the results of the analysis on the data coverage page
You can run the data coverage task and view the results in the data coverage page. You can edit the results view to select and view specific cells in the results.
Edit the parameters used in the analysis
You can edit the parameters including the columns and filters applied and view updated analysis results in the data coverage page.
Update data values in the source data
You can update data values across cells that you analyze. For example, based on the data coverage analysis results, a cell contains data values below the minimum threshold that you set. You can update data in other cells to create the minimum required data values in the cell.
