Device, system and method of modeling homogeneous information. For example, a method that includes providing to a model-based application an input model including a refinable homogeneous record having a base type, wherein said homogeneous record is defined with a homogeneous constraint to only include data members of a type compatible with the base type. The homogeneous record is defined in a modeling environment that is able to automatically enforce the homogeneous constraint for the homogeneous record and for refinements thereof.
