In my terminology I call this “doing bad things to data”. A better term is a Business Rule.

Typically the Extract Load and Transform (ELT) code that is written in the data platform is made up of multiple Business Rules. Key Performance Indicators (KPI’s) are also comprised of multiple Business Rules.

Some examples of Business Rules in the data space may include:

  • Filtering or joining data to give it context
    For example identifying Customer records
  • Augmenting Data
    For example flagging a customer as a “Gold” customer
