An efficient temporal database design method based on EER
2007
Many existing methods of modeling temporal information are based on logical model, which makes relational schema
optimization more difficult and more complicated. In this paper, based on the conventional EER model, the author
attempts to analyse and abstract temporal information in the phase of conceptual modelling according to the concrete
requirement to history information. Then a temporal data model named BTEER is presented. BTEER not only retains all
designing ideas and methods of EER which makes BTEER have good upward compatibility, but also supports the
modelling of valid time and transaction time effectively at the same time. In addition, BTEER can be transformed to
EER easily and automatically. It proves in practice, this method can model the temporal information well.
