Abstract: A method for auditing databases containing records of varied record formats verifies records from a test database against records from a reference database. Records from the test database are converted to test tokens, and records from the reference database are converted to reference tokens. The tokens summarize select fields of data from the records. Thereafter, pattern recognition techniques are used to analyze the tokens to determine Whether the data in the test tokens matches to data in the reference tokens. When an erroneous test token is discovered, an update token is generated to correct a corresponding record in the test database. This method is particularly well suited for auditing enhanced 911 emergency telephone service selective router databases.
