The document discusses the differences between filters and queries in databases. Filters are used to find specific data that meets criteria, while queries can be saved, printed, and have specific fields displayed in the results. It provides examples of using comparison operators (<, >, <=, >=, =, <>) to define filter criteria and discusses using connectors (AND, OR, NOT) to combine multiple criteria. It also demonstrates how to create and run both filters and saved queries in an Access database.
