“…The Semantic Temporal EER model (STEER) [8], [9] was developed in order to compensate for a lack of consideration of the semantics associated with time in previous research that had concentrated on temporal data models and query languages in the context of the relational model and not so much in the context of conceptual data models. STEER introduces a new classification concept for temporal and conceptual objects and provides guidelines for identifying objects as conceptual or temporal.…”

“…As indicated in an excellent survey [31], several temporal conceptual models have been proposed in prior literature. Prior approaches to temporal conceptual modeling (for example, [11,25,29,30,37,49,74]) provide different levels of support for modeling temporal data semantics including timestamping constraints, evolution and transition constraints, and lifespan cardinality constraints [33]. Timestamping constraints distinguish between those elements of the schema that change over time from those that do not, evolution and transition constraints focus on migration of entities from one class to another, and lifespan cardinality constraints focus on cardinalities over the lifespan of entities.…”

“…STERR [EK93] es un modelo temporal semántico, distingue entre entidades, interrelaciones y atributos conceptuales y temporales, donde éstas últimas son tratados (a diferencias de aquellas) como de existencia permanente, la forma de representar el tiempo es similar a la planteada en TEER; este modelo considera solo el tiempo válido.…”
