Abstract: A method of using a computer system 20 to implement a graphical interface 10. The method displays a graph 160 of data from a database system 11, and permits a user to change the data by changing the appearance of the graph 160. The graph 160 is generated from a stored graphics engine 12, which contains rules for generating graphical objects comprising the graph and the objects' attributes. The graphical objects and attributes are matched to data delivered from the database system 11. If the user manipulates a graphical object, the graphical interface 10 associates the change to a new data value, and updates both the graph 160 and the data in the database system 11.

Abstract: An apparatus and method for assisting persons in making decisions, using a computer programmed with artificial intelligence techniques. Real world objects and events pertaining to a particular domain are represented in a knowledge base. Best choices for solving problems are made according to the application of rules, which may be applied absolutely, comparatively, by weight, or ordered, according to methods selected by the user. The invention also permits the user to select from among various decision making strategies and permits the user to observe the effects of choices in hypothetical scenarios.
