ABSTRACT:
The invention is a method of determining the contents of a selected data field. The steps begin by attaching, from an application program, a database to be mapped. Once the database is attached, a field identification module (FIM), will scan the contents of the database to determine a data field identifier for each of the data fields to be worked upon. The FIM will then compare each of the data field identifiers with a list of known identifiers stored in a repository and assess a first score in respect of the comparison wherein the score is representative of a probability that the comparison is an accurate comparison. When a first probability score has been determined, the FIM will sample the data field according to a pre-selected list of requirements and make a second comparison with the data field. The FIM will then assess a second score. After sampling and scoring the data field, the FIM will construct a test case wherein the data field is used in the postal coding or host application and a third comparison is made in respect of the test case. The FIM will then assess a third score. The FIM will choose a field type based on the weighted average result of the three scores, and then request that the system operator confirm the selected field type. Once confirmed, the data field identifier and the data field represented thereby are added to the repository as one of the known identifiers.
