title: Schema users and permissions
body: <p>From the documentation I understood that the schemas are related to one user. I want to create 6 schemas that each will have its tables, but I want just one user that can connect through php and insert some data in those tables (will hace access to the other schemas).</p>
  
  <p>I know you can just assign the CONNECT and RESOURCE roles to those users, but from what i read its not the best option regarding security.</p>
  
  <p>I thought about making 2 roles, one for the schema users and another for the php user. </p>
  
  <p>For the php user: GRANT CREATE SESSION, UNLIMITED TABLESPACE to 
  For the schema users; but do i need some privileges for these users? Since they will not be accessed</p>
  
  <p>Is this a correct way to do this?</p>
