Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for constructing and implementing a universal extension module for processing objects in a database. SOLUTION: A multi-tier database architecture comprises an object-relational database engine as a top tier, one or more domain-specific extension modules as a bottom tier, and one or more universal extension modules as a middle tier. The individual extension modules of the bottom tier operationally connect with the one or more universal extension modules which, themselves operationally connect with the database engine. The domain-specific extension modules preferably provide such functions as searching, indexing, and retrieval services of images, video, audio, time series, web pages, text, XML, spatial data, etc.

Abstract: Methods, systems, and program products for managing multimedia content. These are built upon a combination of a high level content model for specific multimedia content types and a low level physical for mapping to a data engine. The method, system, and program product include representing multimedia content management objects and managing the objects in a relational database. The relational database is adapted for representing data in a plurality of relational database tables, where each of the relational database tables has at least one row with a plurality of columns. Content is managed by associating the object as an item to a row in a first relational database table; and associating additional components, if any, of the object to additional relational database tables.

Abstract: In a searching for library documents that match the content of a given sequence of query words, a set of equivalent words are defined for each query word along with a corresponding word equivalence value assigned to each equivalent word. Target sequences of words in a library document which match the sequence of query words are located according to a set of matching criteria. The similarity value of each target sequence is evaluated as a function of the corresponding equivalence values of words included therein. Based upon the similarity values of its target sequences, a relevance factor is then obtained for each library document.
