Abstract: A computer validates relationships between object classes in object models. The computer detects user input to join a first object class and a second object class corresponding to user-selected object icons. The computer also detects user selection of a first linking field from a plurality of data fields for the first object class and user selection of a second linking field from a plurality of data fields for the second object class. In response, the computer generates a relationship that connects the first object class and the second object class according to shared data values of the first linking field and the second linking field and displays a relationship summary, including information regarding cardinality of the relationship and information regarding referential integrity of the relationship. The computer also displays a visual connection between the user-selected object icons representing the first and second object classes.

Abstract: A computer displays, in a user interface, a data field region and an object model visualization region that includes object model icons. The computer detects user input to join a first object class and a second object class and detects user selection of a first linking field and user selection of a second linking field. In response to receiving the user selection of the first linking field and the second linking field, the computer generates a relationship that connects the first object class and second object class according to shared data values of the first linking field and the second linking field. The computer also displays, in the data field region, information regarding cardinality of the relationship and information regarding referential integrity of the relationship. The computer also updates the object model visualization region to display a visual connection between the object icons representing the first and second object classes.
