<p>PURPOSE:To enable even a less experienced user to easily perform target retrieval by optionally arranging buttons respectively corresponding to character strings, predicted principal keys for retrieval on a display screen, and clicking or selecting, corresponding buttons to retrieve the target character strings. CONSTITUTION:The buttons corresponding to the character strings are optionally arranged as the predicted principal retrieval keys on the screen 1 of the display of a computer. When the button 2 of a character string such as 'Welsh onion' necessary for retrieval is clicked, a menu list 3 obtained by retrieving dishes using a corresponding material, i.e., 'Welsh onion', is displayed on the screen. Consequently, the technique is easily mastered and acquired, and anybody can generate a data base at his or her own pace with a game feeling and also retrieve information at his or her own pace.</p> |
