The IMS (Information Management System) ADF (Application Development Facility) uses an auditor to validate input data, perform application logic, and process application data. The auditor uses a symbol dictionary technique to process this data and deals with segments of application data as though they are unique. The uniqueness extends to the field level so that fields in different segments are considered different even if they are to hold the same kind of information. However, in some cases, applications call for data in certain segments to be processed as multiple occurrences of the same kinds of data rather than as different kinds. Under IMS, data segments of the same type that occur together in a data base structure are called twin segments.
