<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">Let's say we are going to develop a application for a bank, or any other enterprise, this application need a DB. And we decide to choose Oracle 12c. Then we make a plan:</span>

Application is for WBBANK, so name is WBBANK
Application DB is running in a individual PDB
Application DB has its own tablespace
There are two users for this DB, one is to administrate objects of the DB (schema), which is used by DBA and other one is to operate the data, which is used by application

Following is details:

1. Create PDB and its DBA user

sqlplus sys as sysdba

CREATE PLUGGABLE DATABASE PDBWBBANK
  ADMIN USER wbbank_dba IDENTIFIED BY oracle
  ROLES = (dba)
  DEFAULT TABLESPACE WBBANK_DEFAULT
    DATAFILE '/u01/app/oracle/oradata/orcl/pdbs/pdbwbbank/wbbank_default.dbf' SIZE 100M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED 
  STORAGE (MAXSIZE 2G MAX_SHARED_TEMP_SIZE 100M)
  PATH_PREFIX = '/u01/app/oracle/oradata/orcl/pdbs/pdbwbbank/'
  FILE_NAME_CONVERT = ('/u01/app/oracle/oradata/orcl/pdbseed/','/u01/app/oracle/oradata/orcl/pdbs/pdbwbbank/');

2. Open PDB

alter pluggable database pdbwbbank open;

Now you can remote access this pdb with service name, pdbwbbank.

3. Create tablespace

conn wbbank_dba/oracle@pdbwbbank

create tablespace WBBANK datafile '/u01/app/oracle/oradata/orcl/pdbs/pdbwbbank/wbbank01.dbf' size 100M autoextend on next 10M MAXSIZE UNLIMITED;

4. Create admin user and app user

create user wbbank_owner identified by oracle default tablespace WBBANK quota unlimited on WBBANK;
grant connect to wbbank_owner;
grant resource to wbbank_owner;

create user wbbank_user identified by oracle default tablespace WBBANK quota unlimited on WBBANK;
create role wbbank_user_role;
grant create session to wbbank_user_role;
grant wbbank_user_role to wbbank_user;

5. Test

conn wbbank_dba/oracle@pdbwbbank

-- Create table users in schema wbbank_owner
CREATE TABLE wbbank_owner.users
( id number(10) NOT NULL,
  username varchar2(50) NOT NULL UNIQUE,
  password varchar2(50) NOT NULL,
  create_date TIMESTAMP DEFAULT SYSDATE,
  CONSTRAINT users_pk PRIMARY KEY (id)
);

--Must grant access privileges to wbbank_user or wbbank_user_role, otherwise synonym is useless
grant all privileges on wbbank_owner.users to wbbank_user_role;

--Create private synonym in schema wbbank_user
create synonym wbbank_user.users for wbbank_owner.users;

Try

conn wbbank_user/oracle@pdbwbbank

select * from users;

Remarks

wbbank_owner is to manage objects, all objects are created under wbbank_owner. It has RESOURCE role. Please note RESOURCE role doesn‘t have synonym creation role.
wbbank_user is only to operate data through synonyms.
wbbank_dba create synonym and grant privileges to data operator, wbbank_user. It has DBA role, it‘s DBA of this PDB.
