MSI Feature Table

Feature table explains the logical tree structure of features. There should be atleast one feature in every MSI file. And a feature can have a parent and child features also. Feature table contains the list of features that are present in a specific MSI file. The following are the columns of Feature table:

For example suppose there are two features Feature 1 and Feature 2 in a specific msi file.  Suppose ‘Feature 1’ feature is child feature of ‘Feature 2’ feature.

Let us discuss about the feature ‘Feature 1’.

Feature Column:

 It is a Primary key used to identify a particular feature record. Feature column shows Feature 1 as primary key for feature Feature1.

Feature_Parent:

Feature 2 will be its parent feature, since Feature 1 feature is a child feature of Feature 2.
