Crow's foot notation is a common method used for cardinality notation in database modeling. The notation uses crow's foot symbols that represent the cardinality between two entities in a database schema. The shapes used in crow's foot notation include circles, bars, and symbols that indicate various possibilities. On the other hand, big O notation is used in computer science to express the performance of an algorithm. Dark resistor's notation and hash topology notation are not standard methods of cardinality notation.
