<p>The present invention provide a system and method for displaying on a display device (20) connectable to the system a visual representation of a physical environment, the system having display means (30) for displaying objects in the physical environment including a data management object, one or more data objects representing data sources, and one or more output objects representing means through which data from a data source can be presented to a user, a user-operated device (50) being connectable to the system to allow a user to interact with the objects. The system further comprises data receiving means (70), responsive to signals from the user-operated device (50) indicating user association of one or more data objects with the data management object, to access the data represented by the one or more associated data objects. Additionally, processing means (90) are provided for performing selected processing operations on the retrieved data, and an output means (100) is employed to pass the data processed by the processing means to a selected output object. The use of the data management object simplifies the user's interactions with and access to data, and provides a common mechanism for connecting any input data to any output objects, optionally processing that data on the way. It also provides a mechanism for performing relational database queries in a vastly simplified manner adhering to a concrete, accessible, real-world metaphor. <IMAGE></p> |
