    1. The act of uniting or joining two or more things into one,
       or the state of being united or joined; junction;
       coalition; combination.
    Note: Union differs from connection, as it implies that the

          whereas things may be connected by the in???vention of
          a third body, as by a cord or chain.

       affections, or the like; harmony; concord.

             ``singular,'' and by themselves alone. --Holland.

    6. A device emblematic of union, used on a national flag or
       ensign, sometimes, as in the military standard of Great
       Britain, covering the whole field; sometimes, as in the
       flag of the United States, and the English naval and
       marine flag, occupying the upper inner corner, the rest of
       the flag being called the fly. Also, a flag having such a
       device; especially, the flag of Great Britain.
    Note: The union of the United States ensign is a cluster of

Computing Dictionary

1. An operation on two sets which returns the set of all elements that are a member of either or both of the argument sets; normally written as an infix upper-case U symbol. The operator generalises to zero or more sets by taking the union of the current partial result (initially the empty set) with the next argument set, in any order.

For example, (a, b, c) U (c, d, e) = (a, b, c, d, e)

2. A type whose values may be of one of a number of other types, thet current type depending on conditions that are only known at run-time. A variable of union type must be allocated sufficient storage space to hold the largest component type. Some unions include extra information to say which type of value the union currently has (a "tagged union"), others rely on the program to keep track of this independently.

A union contrasts with a structure or record which stores values of all component types at once.

3. An sql operator that concatenates two result sets, that must have the same number and types of columns. The operator may be followed by the word "ALL" to indicate that results that appear in both sets should appear twice in the output.
