Abstract: A graphical user interface (GUI) tool is presented to a user for interacting with an underlying database. The GUI tool includes a field selection and attribute selections for the field. The user selects a field and an attribute for that field and is presented with a first list of values retrieved from the database for the selected attribute. Next, the user selects a filter for the attribute within the GUI tool and a second reduced list of values is presented to the user within the GUI tool representing the filtered first list of values acquired by applying the filter.

Abstract: Apparatus, systems, and methods may operate to receive user-specified input data from a user input device as a segment query that includes a plurality of criteria, and to store individual counts and at least one additional count in a storage medium. The individual counts are derived from processing the segment query as a corresponding plurality of queries associated with each of the criteria, and the at least one additional count comprises an intersection of at least two of the criteria, regardless of whether the user-specified input data includes an intersection operation. Other apparatus, systems, and methods are disclosed.
