The Data Profiling Results page displays a comprehensive analysis of a profile, including the completeness and uniqueness of the contained data. The report is generated at the profile level as well as table and column level. At the column level the result displayed varies depending upon the profiling rules selected by you. For example, if you select Semantic Analysis rule on the Add Profile page, the Data Profiling Results will show the detected semantic types in the selected string columns.
Note: In all the charts, legends are hyper-linked and those lead you to individual records in the category.
You can download the results in the PDF or Excel format.
Note: If the Java Virtual Machine does not have the required fonts, the downloaded reports will be empty files and the error logs will indicate that the fonts are not available to the JVM. To install the missing font files (.ttf), follow the instructions here:

    • Description: A brief description of the profile
    • Started: The date (yyyy/mm/dd), time (hh:mm:ss), and period (AM or PM) when the profile analysis was initialized.
    • Data Source: The source of the data in the profile being analyzed. It can be a physical or logical model or a direct data source connection.

  • The report pane gives a pictorial view of the analyzed data

The report displayed in the right pane is based on what you select in the left pane (profile, table, or column). Details, such as Standard deviation (Stdev), Maximum (Max), Minimum (Min), and Average value are displayed at the column level for numerical data, while length frequency and text pattern frequency is displayed for string columns. Besides, based on the rules selected for profiling, additional tabs are displayed in the report, such as Semantic Type for columns having semantic type values if Semantic Analysis rule is selected.

Additionally, you can collaborate on your profiling results using the comments feature available at the model, table, and column level. For more information, see Collaborating on Data Profiling Results.
