- the computer 102 reads the program using the hard disk 103 and transmits the program to the personal computer 100 via the communication line 101. That is, the program is embodyed into a carrier wave as a data signal and transmitted via the communication line 101. in this way
- the program can be supplied as a computer-readable computer program product in various forms such as a
- search data examples of name search data, telephone number search data, and address search data have been described as search data, but the present invention is not necessarily limited to these contents.
- Other search data may be used. That is, any search data used for specifying the position may be used.
- the corresponding entity data is extracted and its contents are displayed in step S26 in FIG.
- both the entity record extracted by comparing the search tree and the updated data extracted by comparing the index part of the updated data are extracted and displayed on the monitor 18.
- the entity data of the extracted entity record matches the entity data of the update data
- only the entity data of the update data may be displayed. Since the update data updates old entity data, the entity data of the entity record does not completely match the entity data of the update data. Therefore, if the entity data can be regarded as substantially matching, it may be considered as matching. For example, if two or more (multiple) of the name, address, telephone number, and location information match, it may match, or if the data almost match (for example, 80% or more), They may match.
