A Bitemporal SQL Extension

.
ACEEE International Journal of Information Technology, 3 (3): 9 (September 2013)

Abstract

A bitemporal nested query language, BTN-SQL, is proposed in this paper. BTN-SQL attempts to fill some gaps present in currently available SQL standards. BTN-SQL extends the well-known SQL syntax into two directions, the user-friendliness support of nested relations and the effective support of bitemporal data. The schema of a bitemporal nested database is difficult to be understood since it is complicated by nature; therefore, an extended approach of the Entity- Relationship model, the BTN-ER model, is also proposed for modelling complex bitemporal nested data.
