Final answer:
Emails in a Data Governance Center can be sent using a mailTask defined in .bpmn files, a Script task that calls a mail plugin, or a Mailing script, all of which depend on the software's functionality.
Step-by-step explanation:
When handling emails in the Data Governance Center, one typical approach mentioned is the use of a mailTask within an Activity. This functionality is often designed into the workflow of data governance software to facilitate automated email communication. Essentially, a mailTask is predefined within the .bpmn files (Business Process Model and Notation) which are part of the software's process management system. However, alternative methods such as a Script task that calls a mail plugin, or a dedicated Mailing script, might also be used, depending on the capabilities and configuration of the specific Data Governance Center software in question.
