Oracle Multimedia (formerly Oracle interMedia from versions 8 to 10gR2[1]) is a feature available for Oracle databases, which provides multimedia utilities in a database environment, generating as a result a multimedia database (MMDB). Oracle Multimedia was deprecated in Oracle 18c[2] and desupported in Oracle 19c.[3]
Functionalities
Oracle Multimedia is a framework which:[4]
- as a general-purpose feature enables the management and retrieval of image, audio, and video data
- recognizes the most popular multimedia formats and can automate metadata extraction and basic image-processing
- facilitates the development of multimedia applications using JSPs, servlets, PL/SQL (with new packages) or tools such as JDeveloper (ADF/UIX) and Oracle Portal.
Oracle Multimedia manages multimedia data within an Oracle database under transaction control (see transaction processing); using by default database schemas named ORDSYS and ORDPLUGINS (the "ORD" prefix designates "object-relational data").
ORDSYS provides four media classes:[5]
- ORDAudio
- ORDDoc
- ORDImage
- ORDVideo
Alternatively, an Oracle database can use Oracle Multimedia to store and index meta-information together with external references that enable efficient access to media-content stored outside the database.
