Using the data load editor

Data connections

Under Data connections you can save shortcuts to the data sources (databases or remote files) you commonly use. This is also where you initiate selection of which data to load.

For more information, see Connecting to data sources and Select data in the data load editor.

Preview

Once the script has been run either with Preview data or Load data, you can view a preview of the loaded tables under Preview.

Preview offers three different views of table data:

• Table view

• List view

• Tile view

Table view

The data view displays data in a table format.

List view

The list view shows a summary of information about the fields and their values.

You can control what columns display by clicking and selecting the desired columns. Selections do not carry over between sessions. The following columns are available:

• Name: Field name.

• Data type: Type of data in the field

• Distinct values: Count of distinct values in the field

• Null values: Count of null values in the field

• Sample values: Selection of sample values from the field

• Sum: If the field is numeric, a sum of the field values

• Min: If the field is numeric, the lowest value

• Max: If the field is numeric, the greatest value

• Average: If the field is numeric, the average value

• Median: If the field is numeric, the median value

• System Tags: Tags added to the data by the Data Profiling Service

• Standard deviation: If the field is numeric, the standard deviation of the values

• Positives: If the field is numeric, the number of positive values

• Negatives: If the field is numeric, the number of negative values

• Zero values: If the field is numeric, the number of zero values

• Empty strings: If the field is textual, the number of empty strings

• Min length: If the field is textual, the number of characters in the shortest string

• Average length: If the field is textual, the average number of characters per string

• Max length: If the field is textual, the number of characters in the longest string

• Last sorted value: Final value, alphabetically or numerically, in a field

• Numeric values: Number of numeric values in a field

• Text values: Number of text values in a field

• Most frequent values: Three most repeated values from the field

• Frequency distribution: If the field is numeric, the frequency distributions of the values

Tile view

The tile view displays available fields with a graphical profile of the data. Depending on the values in the field, each tile displays one of the following visualizations:

• A list of the top three distinct values from the field with a count of each value's instances.

• An area chart showing the range of values, with the average value highlighted.
