source: wikipedia [WP_MAP]:

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type composed of a collection of (key, value) pairs, such that each possible key appears just once in the collection.

Operations associated with this data type allow:

  • the addition of pairs to the collection
  • the removal of pairs from the collection
  • the modification of the values of existing pairs
  • the lookup of the value associated with a particular key
