Abstract:

An apparatus, system, and method are disclosed for managing objects in a database according to a dynamic predicate representation of an explicit relationship between objects. The apparatus includes a correlation module, a storage module, a query module, and a deletion module. The correlation module associates a set of predicate identifiers with a set of predicates. Each predicate is a description of a relationship between objects, or properties of objects. The predicate includes a predetermined number of arguments. The storage module stores a set of tuples in a database. Each tuple includes one of the predicate identifiers and the predetermined number of arguments as required by the predicate associated with the predicate identifier. The query module retrieves a subset of the tuples satisfying a query expression from the database. The deletion module deletes at least one of the tuples from the database.
