Superspace: top-space

Result type: None.

Problem Space Overview:

The ar-set space contains implementation knowledge for the remove operator. No result is returned because the operator is not chunked over. For further discussion of possible problems resulting from this, see black holes.

Problem Space Proposal:

The problem space is proposed in response to an operator no-change impasse on the access operator. This happens when there are more than two items in any relation on the A/R set.

Operators in Problem Space:

remove operator
