1. A method for searching databases, the method comprising: accessing historical incident data from a plurality of databases having different coding representing categories; recoding the different coding to provide a standardized coding of the historical incident data; outputting unified historical incident data from the plurality of databases using the standardized coding to create standardized categories; prompting for product information to be used as parameters for a query; prompting for data sources to be used in the query; prompting for query input, wherein the query input includes at least one of an age range, a year range, a keyword and a product code; submitting the query using the query input to access the standardized historical incident data to produce a query result; and checking whether the query result is sufficient, and if deemed sufficient, signifying an occurrence level and a severity level of incidents for records found during the query, otherwise, filtering the results and resubmitting another query.
3. The method of claim 1 , wherein the accessing step comprises reading the plurality of databases in a native format, and wherein the recoding step includes at least one of recoding numeric codes and text codes, and the recoding step generates standardized coding at least partially different from any of the plurality of databases.
