LBAC security label component type: ARRAY

ARRAY is one type of security label component.

In the ARRAY type of component the order in which the elements are listed when the component is created defines a scale with the first element listed being the highest value and the last being the lowest.

Example: If the component mycomp is defined in this way:

CREATE SECURITY LABEL COMPONENT mycomp 
  ARRAY [ 'Top Secret', 'Secret', 'Employee', 'Public' ]

Then the elements are treated as if they are organized in a structure like this:

The elements are listed in order of decreasing value. Top secret is first, then Secret, then Employee, then Public.

In a component of type ARRAY, the elements can have these sorts of relationships to each other:

Higher than: Element A is higher than element B if element A is listed earlier in the ARRAY clause than element B.
Lower than: Element A is lower than element B if element A is listed later in the ARRAY clause than element B
