Abstract
A database arrangement is provided which presents a user with a results table 56. This had two dimensions. Column headings show classification headings at a selected level of a classification structure. The rows are classified with additional identification of the content of data items within the database. Each point of the table shows the number of data items meeting the two criteria. The user can thus see the number of results available from various alternative refinements of a search strategy, before the search strategy is restricted.
