A general model is introduced and investigated of a great variety of finite structures studied in computer science. The model is referred to as dependence space. The main feature of the model is that it enables us to deal with the indiscernibility-type incompleteness of information that a modelled structure might be burdened with. The model provides a general framework for expressing the concept of independence of a set and the concept of dependency between sets with respect to a dependence space. It is shown that these concepts lay the foundation on which many applied structures rest. The theory of dependence spaces is developed aimed at providing tools for studying the problems relevant for the modelled structures.
