Merging Rules

In Rulex it is possible to merge not only datasets, but also rulesets from different computations.

A single task, called Merge Rules, allows you to do this.

Prerequisites

a Rulex process has been created
the required datasets have been imported into the process
two tasks with different rulesets must be present in the process.

Additional tabs

The following additional tabs are included in the task:

Documentation tab where you can document your task,
Parametric options tab where you can configure process variables instead of fixed values. Parametric equivalents are expressed in italics in this page (PO).

Procedure

Drag and drop the Merge Rules task onto the stage.
Connect two tasks, which contain the rules you want to merge, to the new task.
Double click the Merge Rules task.
Configure the options described in the Merge Rule options table below.
Save and compute the task.

Description

Merge also data

mergedata

If selected, the datasets will be merged along with the ruleset. The datasets will be joined using the row indexes as a key, according to the merge type defined below.

Merge type

cattype

If you have selected to merge datasets along with the ruleset, then select the required merge mode form the Merge type drop-down list. Possible values are:

Inner, whereby the resulting number of rows is the minimum between the number of rows of the input datasets
Outer, whereby the resulting number of rows is the maximum between the number of rows of the input dataset.
