Use derived property values - Latest

Using derived property values is a very powerful technique in Data360 Analyze, which allows you to substitute the values of properties from one (typically centralized) location to another, for consistent reuse of common values across your data flows. For example, paths for input/output data, or parametrized aspects of your analysis, such as locations or dimensions upon which to perform complex analyses.

You can explicitly substitute a property value into another property by typing the following text, where propertyname is replaced by the name of the property:

{{^propertyname^}}

Alternatively, you can select a property to reference from the node property menu:

1. Click the menu button on the node property where you want to insert the reference.
2. Select Property References then choose a property group. Choose from:
   • Data Flow Properties – Properties on the top-level data flow.
   • Run Properties – Run properties defined on the top-level data flow.
   • Container Properties – Properties on the container node of the reference.
   • Local Properties – Properties on the same node as the reference.
3. Select the specific property that you want to reference.

The chosen property reference is inserted at the cursor position in the related field.

A property reference can be combined with further text to build larger values:

{{^rootpath^}}\{{^datafolder^}}\input.csv

out1 += in1

out1.make = unicode

out1 += in1

out1.make = in1.model + ' ' + '{{^make^}}'
