US Patent 11762536 Validating relationships between classes in object models

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.
