Unlike the entity-relationship model, object-oriented systems lack a notion of ``relating'' objects to others: the only means to relate objects are object-valued attributes holding references. This article presents a relationship mechanism for an object-oriented database model that extends known relationship approaches with support for derived relationships, separation of connectivity and visibility, and query language integration. We also introduce a persistence model based on this relationship model, and shortly discuss integrity checking issues.
