Adaptive management of multigranular spatio-temporal object attributes

Camossi, Elena ; Bertino, Elisa ; Guerrini, Giovanna ; Bertolotto, Michela (Springer-Verlag, 2009)

In applications involving spatio-temporal modelling, granularities of data may have to adapt according to the evolving semantics and significance of data. In this paper we define ST2 ODMGe, a multigranular spatio-temporal ...
Adaptive management of multigranular spatio-temporal object attributes

In applications involving spatio-temporal modelling, granularities of data may have to adapt according to the evolving semantics and significance of data. To address such a problem, in this paper we define ST2 ODMGe, a ...
Attribute refinement in a multigranular temporal object data model

Bertino, Elisa ; Camossi, Elena ; Guerrini, Giovanna (Purdue University. Center for Education and Research in Information Assurance and Security, 2009-06)

Temporal granularities are the unit of measure for temporal data, thus a multigranular temporal object model allows to store temporal data at different levels of detail, according to the needs of the application domain. ...
