what is the role of transformation tools in the data management process?

Transformation Tools and Processes For data to become usable by managers, it must first go through a process known in IT-speak as ETL, for extract, transform, and load.

While automated tools from vendors such as Informatica Corporation, Ab Initio Software Corporation, and Ascential Software can ease this process, considerable manual effort is still required. Informatica's CEO Sohaib Abbasi esti- mates that "for every dollar spent on integration technology, around seven to eight dollars is spent on labor (for manual data coding)."
