Architectures with global knowledge may store it in a uniform format in a central database, or may have it in a non-uniform format in a distributed fashion. The uniform method is often employed in systems with a general knowledge representation scheme like frames or first order predicate calculus. The non-uniform method is often used in loosely-coupled architectures for storing speciality knowledge not for general use. Knowledge uniformity is more an issue for global knowledge and representation, which is how accessible knowledge is to the architecture's modules.
