ClassManager has a Set Manager tool that allows for the capturing of multiple data search results and then can perform set algebra (Union, Difference & Intersection) to give you the data results that you need to run an efficient business.

How well a database functions is a combination of many factors. One of those factors is can the database application answer business questions. To do so the database should have a set of tools that allows the user to manipulate the data and find answers to your questions. A simple search form is inadequate for that purpose. It can find only the simplest of data requests. Often you are required to run multiple searches. The problem is that most database products have no means of capturing and holding the results of these multiple searches.
