Data Transforms is the Oracle GoldenGate module for Distributed Applications and Analytics, which can help with column level data transformations during the replicat process.

It's a 2 step process:

1. Configuring a Matcher:

   Matcher configuration helps in identifying target columns, which you want to apply the Data Transforms on.

2. Configuring a Converter:

   Converter defines the logic to be used to convert the matched target columns prior to writing it to the target.
