Usage notes * (any of various data structures) The exact usage of the term , and of related terms, generally depends on the programming language.For example, many languages distinguish a fairly low-level "array" construct from a higher-level "list" or "vector" construct. The prior difference between them is that a list is dynamic, whereas tuple has static characteristics. and tuples are typically used for heterogenous objects (database records etc.) The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values.
