Time in databases has been studied for a long time. Valid time databases capture when the objects are true in the reality. The proposed model allows both representing and querying time in a fuzzy way. The representation and the underlying domain are defined as well as some fuzzy temporal operators. The implementation of the model is developed within the Hibernate framework. The Hibernate framework acts as an abstraction for the running database. Therefore, any relational database supported by the framework can now represent fuzzy valid time in its schema.
