RandomCCType

The RandomCCType transformer is designed to populate specified database columns with random credit card types. This tool is essential for applications that require the simulation of financial transaction data, testing payment processing systems, or anonymizing credit card type information in datasets.

Parameters

Name	Description	Default	Required	Supported DB types
column	The name of the column to be affected		Yes	text, varchar
keep_null	Indicates whether NULL values should be preserved	false	No	-

Description

Utilizing a predefined list of credit card types (e.g., VISA, MasterCard, American Express, Discover), the RandomCCType transformer injects random credit card type names into the designated database column. This feature allows for the creation of realistic and varied financial transaction datasets by simulating a range of credit card types without using real card data.

Example: Populate random credit card types for the transactions table

This example shows how to configure the RandomCCType transformer to populate the card_type column in the transactions table with random credit card types. It is a straightforward method for simulating diverse payment methods across transactions.

RandomCCType transformer example

- schema: "public"
  name: "transactions"
  transformers:
    - name: "RandomCCType"
      params:
        column: "card_type"
        keep_null: false

In this configuration, the card_type column will be updated with random credit card types for each entry, replacing any existing non-NULL values. If the keep_null parameter is set to true, existing NULL values in the column will be preserved, maintaining the integrity of records where card type information is not applicable.
