Finding rules and exceptions from databases
First Claim
1. A method of finding rules and exceptions from a database is characterized by adopting four stages and their realization on computers, the four stages comprising:
- an adaptive stage for creating a parameter file as the rules and exceptions finding conditions according to the receipted specification that is decided by a user, and displaying the result of generated rules and exceptions to the user;
a data model stage for analyzing the parameters from said parameter file and retrieving data from one or more databases according to the parameters;
a problem formulator stage for transforming said retrieved data into a formalized data structure suitable for said parameters, and creating the possible catalog of attributes; and
a solving stage for generating rules and exceptions from said formalized data by using said parameters and said catalog, and sending the result to said adaptive stage.

Abstract
A method for finding rules and exceptions from a database uses four stages programmed into a computer, wherein the four stages include an adaptive stage for creating in accordance with a user'"'"'s previously inputted specifications, a parameter file of rules and exceptions finding conditions in accordance with the user'"'"'s specifications, with the file being displayed to the user; a data model stage for analyzing the parameters from the parameter file, and retrieving data from one or more databases in accordance with the parameters; a problem formulator stage for transforming the retrieved data into a formalized data structure compatible with the parameters, and creating a catalog of possible attributes; and a solving stage for generating rules and exceptions from the formalized data by using the parameters and the catalog, and sending the result to the adaptive stage.
