First, *elementary operations* on data objects are defined – that is, operations that can be assumed to be indivisible so that each individual operation by itself appears atomic and isolated from other operations. (Note that we are not yet considering the embedding of such operations in the context of a transaction.) This first step leaves some leeway in the definition of what a data object is and what kind of elementary operations we consider, and this will later lead to the distinction between the Page Model and the object model.
