Abstract

A method and apparatus of operating a display system for displaying data items stored in an associated database. The database stores a display function for each data item class to be also stored in the database therein. When the user selects a data item class, a data item of and a display function associated with the selected data item class are retrieved from the database. The data item is used as an argument of a display function call. The system displays an object using the display data and the data format returned as the result of the display function call. The system may store multiple representations of each data item such as, pictorial, textual and audio representations which may be selected under user control.

Claims

1. A method of communicating between one or more databases, including at least a relational or an object database, and a display apparatus, said communication identifying data objects in said database which are displayed by said display apparatus, the method comprising a plurality of steps including

storing a display function us associated with each of one or more input-selectable classes of data objects stored in said database;

in response to an input selecting one of said object classes from said database, obtaining an associated display function and executing said display function for one or more objects, of said object class, to be displayed at said display apparatus, said displayed objects being specified by data received in a protocol communication, said protocol controlling communications between said database and said display apparatus and including
