Plural of schema; mental frameworks or organized patterns of thought that help interpret information, or structured representations of data in computing.
From Greek 'schema' meaning 'form, figure, shape,' through Latin. In psychology, introduced by Kant in the 18th century and developed by Piaget in the 20th century. Computing usage emerged with database theory in the 1970s.
From ancient Greek geometry to modern artificial intelligence, 'schemas' represent humanity's eternal quest to organize chaos into comprehensible patterns.
