Abstract: A dynamic object model system identifies, from a first object data definition file, a first object definition of a first object of a first entity type; and identifies, from a second object data definition file, a second object definition of a second object of a second entity type. The first object definition defines an entity identifier for the first object, and the second object definition includes the entity identifier of the first object. The dynamic object model system determines, based on an object model definition, that objects of the second entity type refer to objects of the first entity type by entity identifier. Based on the object model definition, and based on the second object definition including the entity identifier of the first object, the dynamic object model system establishes a reference relationship between the first object and the second object within an object database.
