Oracle Container Database (CDB) vs Pluggable Database (PDB) 

Container Database (CDB): The primary database that contains multiple plugged-in databases. Many operations can be performed at the container level to reduce management costs. A #database is created as either a #CDB or a non-CDB.
Pluggable Database (PDB): A set of #schemas, #objects, and non-schema objects that can be plugged and unplugged from a container database. The PDB appears to #OracleNet and end users as a database in and of itself but is actually managed within a container that may have many PDBs.
