||All label values are hierarchically related members of the classification category defined by the CONSTRAINT object name.
- Data type: smallint
The corresponding constraint column automatically inherits the data type. The smallint data type allows a range of 1 to 10,000 values.
- VALUES: The set of name:value pairs in the hierarchy, for example, for the security clearance category:
Top Secret:4, Secret:3, Classified:2, Unclassified:1
One integer value from the name:value pairs is assigned to each row in a corresponding constraint column. Users may be assigned multiple values.
Row access is based on comparing the session values to the row values.
||All label values are individual compartments in the classification category defined by the CONSTRAINT object name, and have the same relative weight.
- Data type - byte(n).
Allows specification of 1 to 8 times the number of values (compartments) as the number of bytes defined by (n), up to 256 values (32 bytes).
- VALUES - The set of name:value pairs that represent all compartments in the category, for example, for the country category:
USA:1, UK:2, Canada:3, Japan:4...[country:value]
A system uses the user constraint values as the default session value. Row access is based on comparing the session values to the row values.
The system automatically encodes the applicable constraint values as a binary string that represents the value as a unique bit position (rather than a numeric value), allowing up to 256 values to appear in the column.
