Each element in the weak entity set must have a relationship with exactly one element in the owner entity set, [1] and therefore, the relationship cannot be a many-to-many ...
Entity-level controls have a pervasive influence throughout an organization. If they are weak, inadequate, or nonexistent, they can produce material weaknesses relating to an audit of internal control and material misstatements in the financial statements of the company.
Usage of the notion "emergence" may generally be subdivided into two perspectives, that of "weak emergence" and "strong emergence".

In terms of physical systems, weak emergence is a type of emergence in which the emergent property is amenable to computer simulation ...

The strong principle then becomes an example of a selection effect, exactly analogous to the weak principle. Postulating a multiverse is certainly a radical step, but taking it could provide at least a partial answer to a question seemingly out of the reach of normal science: "Why do the fundamental laws of physics take the particular form we ...
In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector, unlike a strong reference.An object referenced only by weak references – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable and ...
