What is CDB and non CDB?
Basically: A non-CDB stores all metadata (system ones and user ones) in the same dictionary. A CDB stores user metadata only in the database dictionary, which have links to a common dictionary that contains the system metadata.
How do I connect to PDB directly?

Starting Oracle 12.2 sys_context(‘USERENV’,’DB_NAME’) will show the name of the Database in CDB$ROOT and the name of the PDB inside the PDB.
What is non-CDB?
A non-CDB is anything that isn’t a CDB; that is, any database before 12c, or a 12c database created without the enable pluggable database clause. If you create a non-CDB it isn’t Multitentant and is a single-instance standalone like a pre-12c database.
What is Oracle PDB CDB?
A PDB is a portable collection of schemas, schema objects, and non-schema objects that appears to an Oracle Net client as a non-CDB . The CDB root is a collection of schemas, schema objects, and non-schema objects to which all PDBs belong The root stores Oracle-supplied metadata and common users.

There is an update of this article for Oracle Database 12c Release 2 (12.2) here. In the initial release of Oracle Database 12c Release 1 (12.1.0.1) remote cloning of PDBs was listed as a feature, but it didn’t work. The 12.1.0.2 patch has fixed that, but also added the ability to create a PDB as a clone of a remote non-CDB database.
How do I convert a non-CDB database to a PDB?
Shutdown the non-CDB database. Connect to an existing CDB and create a new PDB using the file describing the non-CDB database. Remember to configure the FILE_NAME_CONVERT parameter to convert the existing files to the new location.
How do I open a PDB in Oracle without a CDB?
Run the ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql script. This script must be run before the PDB can be opened for the first time. If the PDB was not a non-CDB, then running the noncdb_to_pdb.sql script is not required. To run the noncdb_to_pdb.sql script, complete the following steps: Access the PDB.
What does the DBMS_PDB package do?
The DBMS_PDB package allows you to generate an XML metadata file from a non-CDB 12c database, effectively allowing it to be describe it the way you do when unplugging a PDB database. This allows the non-CDB to be plugged in as a PDB into an existing CDB.
