Theory-based view of category representation
In representation theory, the category of representations of some algebraic structure A has the representations of A as objects and equivariant maps as morphisms between them. One of the basic thrusts of representation theory is to understand the conditions under which this category is semisimple; i.e., whether an object decomposes into simple objects (see Maschke's theorem for the case of finite groups).

In category theory, a quiver can be understood to be the underlying structure of a category, but without composition or a designation of identity morphisms.
