    A consistent extension of the relational model is defined, which allows the recording and manipulation of generic intervals. Two new relational algebra operations are defined, which are closed. The proposed model has a wide range of applications areas, such as engineering, CAD, cartography, version modelling, temporal databases, soil information systems, mathematics, the management of spatial data and many others.
