Abstract

Methods and apparatus for user-directed, efficient comparisons of sets of objects. A user generally selects two sets of objects to be compared. The objects are, in general, hierarchically structured. The user may also specify criteria for selecting a desired subset of objects in the two sets of objects to be compared. In a first phase, the comparison process generates a tree containing nodes representative of each object selected to be compared; an object pair of the sets of objects being compared shares one tree node. Generally, an object pair comprises an object from each of the sets of objects being compared, and an object pair is what is compared. Container nodes are also created which represent folders of the objects being compared. A graphical representation of the tree, or an object view, is displayed as a graphical user interface display on a screen. Once the tree is generated containing nodes for each of the objects selected to be compared, the comparison process performs a comparison of each object pair. The user can select the order of comparison of the object pairs by manipulating the tree nodes in the graphical user interface display. As each object pair is compared, the comparison process generates a result view. As result view comprises the graphical representation of the tree previously generated, with the addition of representations of the result of each object pair comparison performed to that time. The result view, once generated, may be displayed as a graphical usr interface display on the screen.

Claims

1. A method for displaying comparison information for a comparison of two sets of objects, comprising:

generating a node for a tree for each object pair of the two sets of objects in which an object pair comprises an object from a first set of the two sets of objects and a corresponding object from the second set of the two sets of objects;

generating a node for said tree for each object of said first set of the two sets of objects that does not have a corresponding object in said second set of the two sets of objects;

generating a node for said tree for each object of said second set of the two sets of objects that does not have a corresponding object in said first set of the two sets of objects; and

displaying said tree on a display device.

2. The method for displaying comparison information of claim 1, further comprising:

adding a first symbol to a node of said tree for an object pair in which said first symbol indicates that an object of said object pair of said node is in a first set of the two sets of objects and said corresponding object is in the second set of the two sets of objects;

adding a second symbol to a node of said tree for an object of said first set of said two sets of objects in which said second symbol indicates that said object is in said first set of the two sets of objects but is not in the second set of said two sets of objects; and

adding a third symbol to a node of said tree for an object of said second set of said two sets of objects in which said third symbol indicates that said object is in said second set of the two sets of objects but is not in the first set of said two sets of objects.
