Abstract: A Web agent software interface between a relational database and Web-based application programs employs stored SQL procedures to store, update and retrieve multimedia objects. Web based applications manipulate the data in the relational database table by using URLs consisting of an alphanumeric designation of the host computer and port, the Web agent program associated with the database, the database agent configuration information associated with the database, specific stored SQL procedure for performing the desired data manipulation, and additional parameter data needed to specify and manipulate a particular multimedia object.
