ABSTRACT:
A method of retrieving a plurality of records stored in a database first generates a retrieval data set by selecting a plurality of records from the database. Then, an item element of a data item designated from a record in the retrieval data set is specified, and the difference in item elements between optional two records is numerically represented and computed as a dissimilarity. Next, the records in the retrieval data set are plotted and displayed on the display device. At this time, the records are displayed in such a way that the distance between the two records of the plotted records corresponds to the computed dissimilarity, and a new retrieval data set is specified from the displayed records on the basis of an object record designated by the user. Thus, a new retrieval data set can be easily generated within a short time, with mis-retrieval and unnecessarily entered records reduced by plotting the records such that the difference between the records can be readily recognized.
