Top-Down approach
The top-down approach is employed in different computer areas. In distributed databases it correlates a series of stages to the construction of a distributed databases project beginning from the ground and is employed in homogeneous systems [1].
The top-down approach is the more usual given the fact that in the majority of the cases there isn’t a distributed database already implemented. If there is a system already established another approach called bottom-up is used.
