The data management system is applicable, for example, to management of name cards. In management of name cards, name card data (101) includes a plurality of name card records (100). A card summary record (110, 112) prepared as title data includes a card ID and part of item data included in each name card record (100). Each summarized card data (111, 113) includes a plurality of card summary records (110, 112) collected according to a predetermined condition, and is placed into a certain card box (120, 121). Each card box has a characteristic name such as 'business' or 'private'. Visually hierarchical display of data in the form of a card box list, a target list including a plurality of target data, and individual name card data helps the user clearly understand the whole data display and data retrieval. This allows quick access to a desired name card. The target list is data having a fixed length and used on a memory, thereby realizing high-speed data retrieval and display.
