Approximation Spaces were introduced in order to analyse data on the basis of Indiscernibility Spaces, that is, spaces of the form < U,E > , where U is a universe of items and E is an equivalence relation on U. Various authors suggested to consider spaces of the form < U,R > , where R is any binary relation. This paper aims at introducing a further step consisting in taking into account spaces of the form < U,{Ri}i€I> , where {Rii€I is a family of binary relations, that we call "Dynamic Spaces" because by means of this generalisation we can account for different forms of dynamics. While Indiscernibility Spaces induce 0-dimensional topological spaces (Approximation Spaces), Dynamic Spaces induce various types of pre-topological spaces.
