Deferral vs. Delegation
The temporary relocation of state information is referred to as state deferral because the intention is usually to retrieve the information at some later point. We are therefore postponing (deferring) the responsibility of managing the state data. To accomplish state management deferral we temporarily delegate this responsibility to another part of the architecture (such as a database). Therefore, we achieve state management deferral through temporary and periodic state management delegation.
Note that on this Website we collectively refer to the process of state management delegation and deferral as state deferral.
