Abstract

A system and method are provided for managing a plurality of data values which define an attribute of an object. The system includes a computer having a display. The computer has a user defined database or spread sheet which stores the data values. A facility is provided for defining an arbitrary, user defined graphic representing the object; that is displayed by the computer. A region is identified within the graphic. A value is associated with the region. The value represents a visual attribute. The identified region of the graphic is linked to a data field of the database or spreadsheet. The data field stores one of the plurality of data values. A rule is applied to determine the value of the visual attribute as a function of the data value stored in the data field. The visual attribute of the region is automatically changed according to the rule when the data value changes. An exemplary system displays a graphic representing the bottom of a truck. The individual regions of the graphic represent the tires of the truck. The regions representing tires are colored as a function of tire tread depth, tire age, or both tire tread depth and tire age.

a value which defines the argument by type,

an identifier of a database in which the plurality of data are stored,

a query that is used to retrieve the one data value from the database for use as the value of the argument, and

the rule, wherein the rule defines the value of the visual attribute as a function of the value of the argument, and

means for automatically changing the visual attribute of the region in accordance with the rule when the one data value changes.

9. A system according to claim 8, wherein the region identifying means includes a region data structure for the region that stores:

a region identifier, and

a plurality of position coordinates defining a location of a point in the region.

10. A system according to claim 9 further comprising a single file structure which contains:

image data representing the graphic;

a plurality of region data structures, the region data structure being included in the plurality of region data structures; and

a plurality of rule data structures, the rule data structure being included in the plurality of rule data structures.

11. A system according to claim 10, further comprising means for displaying the graphic and a plurality of region indicators, each region indicator being superimposed on a respectively different one of the plurality of regions.

12. A system according to claim 10, further comprising means for generating and transmitting a message which identifies a number of regions in the plurality of regions, and the region identifier, the visual attribute value, and the position coordinates stored in each region data structure.
