“…We did not find a study that offers methodical support for working with multiple domains. Many studies Spinellis (2001), Lochmann and Hessellund (2009), Abouzahra et al (2005), Cuadrado and Molina (2009), Purao et al (2000), Campos et al (2014), Abouzahra et al (2017, Golra et al (2016a), Degueule et al (2015), Emerson and Sztipanovits (2006), Marvie (2004), Erdweg et al (2012), Kühne et al (2009), Vallecillo (2010), Evans et al (2003), Clark et al (2003), France et al (2007) offer mechanisms for dealing with multiple models and their integration, but those mechanisms are not explicitly merged with the specification technique that was used to create the original models. A method to create a DS or domain-based specification could provide certain model properties which make the models easier to integrate, e.g., being in the third normal form, or being context free.…”
