I suggest you read the Oracle Concepts Guide (oracle.com/pls/db112/to_pdf?pathname=server.112/e25789.pdf) where each of these are discussed. Even a simple search for these terms in the documentation would lead you to a quick answer. oracle.com/pls/db112/homepage?remark=tahiti – Leigh Riffel Jun 29 '12 at 12:38
