Ihis paper extends the bundle to be able to represent the constraint condition. The bundle is a container of objects and/or other bundles, while an object is a unit representing the entity in the database that is created in the bottom-up manner, and is frequently updated. The relationships are represented with bundles. Introducing the constraint condition into the bundle makes it possible to maintain the constraints of the relationships as well as the constraints of the bundles themselves. The constraint condition is the disjunction of the bundle condition and the object condition. The object condition is for the exceptional objects. This paper presents how to describe the constraints of the bundle, and the constraints of the relationships. The prototype system managing the constraints is also demonstrated.
