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. A clipboard application program provides a graphical user interface which a user may employ to select and view selected multi-media objects stored in selected relational database tables, and to transfer the Web URLs designating those selected objects to other Web applications, such as HTML authoring tools, using convenient 'drag-and-drop' and 'cut, copy and paste' operations. The Web agent program retrieves data from the database which are designated by such URLs, and accepts POST requests from HTML forms which are activated by the user of a Web browser to load or update data in the relational database.
