ALVEZ, Carlos E  and  VECCHIETTI, Aldo R. Experiences in Image Management by Content in Object-Relational Databases. Cienc. docencia tecnol. [online]. 2009, n.39, pp.187-213. ISSN 1851-1716.

In this paper, several alternatives for the storage of still images in databases given by the Object-Relational technology are analyzed. The aim was to study, by means of two examples, implementation in Oracle 10g database, the technology behaviour in the storage, query formulation and image recovery. The first application corresponds to the storage of medical images complying with DICOM (Digital Imaging and Communications in Medicine) standard, Oracle 10g ORDImage objects have been used for this case. The second example deals with the storage of images for a digital newspaper for which SI_StillImage of the SQL/MM standard have been employed. The capabilities provided by the Object Relational technology facilitate the implementation of an images server. The advantages and drawbacks of using SQL/MM standard or native objects corresponding to Oracle 10g are also compared.
