Oracle 12c Gives Fresh Life to the Relational Database Movement

FOR IMMEDIATE RELEASE
San Francisco (April 1, 2013) – In a dramatic move calculated to give fresh life to the moribund relational database movement, the latest version of Oracle Corporation’s flagship database has eliminated the famous “join penalty” by making it possible to store rows from multiple relational tables in the same database block. There are two flavors of the feature: hash clusters and indexed clusters. Database aficionado Iggy Fernandez has this to say about the feature: “Even Homer Simpson and his Springfield buddies are aware that Oracle Database supports the relational model. However, it is not universally known that Oracle Database 12c also supports the document model. Hash clusters and indexed clusters are critical building blocks of Document/Relational duality, an extension of the physical data independence proposed by Dr. Edgar Codd (1923–2003), the creator of the relational model. Document/Relational duality means that data in an Oracle 12c database can be physically stored in one of the two ways—either as documents or as rows in tables depending on the primary use case—without compromising the ability to expose and manipulate data in the other way. Naysayers will no longer be able to call Oracle Corporation’s commitment to Document/Relational duality into question.” Iggy then ecstatically began singing the 1960s hit song “To everything there is a season and a time for every purpose under heaven,” a dead giveaway to his age.
