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.

Document/Relational duality means that data in an Oracle 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.

    I wonder why there isn’t a word about the merger of Microsoft Corporation (MSFT) and Oracle Corp. (ORCL) and standardizing on SQL Server as the main database for the new company. Oracle Corp. will make a port of SQL Server to Oracle Linux, its flagship OS.

    “moribund relational database movement.”

    Am i alone to have missed the colapse of sales by Oracle corps or you can elaborate a bit more on this?
    Bigdata or NoSql have their own qualities but I still have to receive an invoice issued by one of these.system.

      Thanks for the quotable quote. I’ll use it in my presentation at Great Lakes Oracle Conference.

      Soul-searching for the Relational Movement: Why NoSQL and Big Data Have Momentum

      In this session we will explain that the perceived deficiencies of relational technology are actually a result of deliberate choices made by the relational movement in its early years. NoSQL and Big Data technologies would not have gained popularity if they did not excel at certain tasks which relational implementations cannot handle well. Instead of pretending that new problems do not exist, the relational movement needs to do some serious soul-searching. We will conclude that, with a single notable exception, all the new requirements could have been handled within the framework of relational technology.
