INTELLIGENT EDITING OF RELATIONAL MODELS

In one embodiment, receives a user gesture indicating an edit to be performed on a target object within a model. The model is based on an underlying schema including constraints that define relationships between objects in the model, including the target object. The computer system determines that at least one of the constraints in the underlying schema is associated with the indicated edit of the target object and determines that the edit is valid. The valid edit complies with the constraints associated with the indicated edit of the target object. In another embodiment, a computer system receives a user gesture indicating an edit, determines that a constraint in the underlying schema is associated with the indicated edit, and provides an indication of a valid model edit to a computer user.
