piece of user-oriented call information to a field or fields in the call record. The mapping scheme takes into account the structure code and the values of other fields within the call record in locating the user-oriented call information. The result is that when users need to search for calls associated with a particular telephone number or credit card number belonging to some individual (returning to the previous example), they can refer to the information using common language terms (e.g., "billing number" instead of "tandem digits dialed 1") that are representative of the information sought, and can avoid the use of SQL operators and syntax. This query method allows users to simply associate values of interest with the information of interest, as shown in Figure 1.
