Abstract: A device, system, and computer implemented method for storing segmented data in a computer memory, the segmented data indicating which of a plurality of entities belong to which of a plurality of segments, each segment accommodating entities sharing a single binary characteristic. A computer receives a list of entity identifiers selected from a sequence of entity identifiers, each entity identifier in the list representing an entity which belongs to a segment; the computer uses the list to create a bitmap in which each bit has a bit position in a bit sequence corresponding to the sequence of entity identifiers. The state of each bit indicates whether the entity identifier representing that position in the sequence identifies an entity belonging in the segment or not; and the bitmap is stored in a memory in association with a segment identifier, as the segmented data.
