In a server (), all column data items are extracted from a master data storage unit () and sent to a client () in addition to target data corresponding to a data acquisition request that has been sent from the client (), and in the client (), the target data and data items received from the server () are displayed on a screen in a user-interface selectable mode, thereby making it possible to download from the server () to the client () the minimum target data required when attempting to perform a desired process on the client (), and doing away with the waste associated with downloading all the data. In addition, by also downloading and displaying in a selectable manner on a screen data items pertaining to data other than the target data, a user can be shown, in an operable-like manner, data items pertaining to actual data without downloading the actual data.

Data processing system, and program for managing data

By converting address informationinput to a geocoding unitinto a tree structure formed hierarchically in an administrative district, generating address tree information obtained by associating latitude and longitude information with at least a node of the lowest layer in each branch of the tree structure and storing the address tree information thus generated in a high-speed accessible memoryto proceed a retrieval while tracing the address tree information in order from a parent node to a child node to narrow down a retrieval range, it is possible to efficiently search latitude and longitude information corresponding to given address information therefrom and to perform a retrieval at a higher speed as compared with the related art in which access is given to a conversion table stored in a disk.
