Abstract: “Interoperability is the ability in which systems and enterprises could interrelate and incorporate to each other. With the purpose of improvement of interoperability between systems, an interoperability model isrequired. This study aims at reviewing existing research on interoperability models in order to identify a comprehensive interoperability model. In this review study, all of the existing models for interoperabilityare presented. The majority of the interoperability models focuses only on three of four interoperability types. The existing models are also not at a satisfactory level of development for improvement of interoperability between systems. Thus structuring interoperability models into one single comprehensive and complete interoperability model is necessary in order to ensure consistency and avoid redundancy. In addition, we need to identify metrics and properties to allow better development of interoperability between systems.”
