| + | An IR of any object is a description of that object in terms of its properties. A successful description of a particular object usually involves a selection of properties, those that are relevant to a particular purpose. An IR of <math>L(\text{A})\!</math> or <math>L(\text{B})\!</math> involves properties of its elementary points <math>w \in W\!</math> and properties of its elementary relations <math>\ell \in O \times S \times I.\!</math> |

− | To devise an IR of any relation R one needs to describe R in terms of properties of its ingredients. Broadly speaking, the ingredients of a relation include its elementary relations or n tuples and the elementary components of these n tuples that reside in the relational domains. | + | To devise an IR of any relation R one needs to describe R in terms of properties of its ingredients.
