Give an example of a DES that meets the complementation criteria (property) in one round?

The following results would occur if those procedures were abandoned when a deadlock was reached:

2NF and 3NF are defined differently by the main key definitions than they are by the generic definitions. Give a specific example to support your claim.

What is an example of a supertype/subtype connection in which the disjoint rule is applicable?

A connection like sec course may be built from a collection of many-to-one connections. To what extent do the primary and foreign key restrictions enforce the many-to-one cardinality limitation of the relation? I was wondering why you came to that conclusion.

To be more clear, what do you mean when you say "interpolation of characteristics"?
