- (1) a statement with one or more arguments implying a constraint among coocurring values of these arguments. e.g., a mathematical function such as the logarithm, an ordering such as "is greater than" or "causes," a statement of association such as "is married to," a correspondence, a code. equivialently (2), a subset of elements of a cartesian product set (wiener). when that subset contains observed or permissible coocurrences, its complement in the same product set is called a constraint and contains conceivable coocurrances that did not occur or are excluded. relations are of different ordinality. unary relations or properties are of order one. binary relations are of order two, etc. relations may be combined to form new relations, e.g., the simple ternary relation of "off-spring" which relates a father, a mother and a child can be used recursively (->recursion) to generate a whole family tree. more than one relation may be defined in the same cartesian product set as the relations "talked to," "is married to" "exchanged goods with" all of which are subsets of the product of two sets of people.
- A set of objects.
- A structure composed of attributes (individual characteristics, such as name or address, corresponding to the columns in a table) and tuples (sets of attribute values describing particular entities, such as customers, corresponding to the rows in a table). within a relation, tuples cannot be repeated; each must be unique. further, tuples are unordered within a relation; interchanging two tuples does not change the relation. finally, if relational theory is to be applicable, the domain of each attribute must be atomic- that is, a simple value, rather than a structure such as an array or a record. a relation in which the domains of all attributes are atomic is said to be normalized or in first normal form.
