What is the terminology used for registering an existing database with Era?

The term "Brownfield" is used in IT to describe projects that work with pre-existing systems. In the context of Nutanix Era, registering a database that was created and exists outside of Era is referred to as a Brownfield deployment. This process onboards the database, allowing Era to manage its lifecycle, including cloning and data protection, by creating a Time Machine for it.

A. Greenfield Database: This refers to a new database provisioned from scratch by Era on the Nutanix cluster, not an existing one.
C. Cloned Database: This is a copy of a database created within Era from a Time Machine snapshot of a source database.
D. Source Database: This is a general term for a database managed by Era that serves as the source for operations like cloning or replication.
