Uni-temporal Modelling Extension at the Object vs. Attribute Level
Michal Kvet, Karol Matiaško · 2013
Today's requirement for the database systems is to provide management for historical and future valid data. Uni-temporal system is one of the most frequently used temporal structure. The time component in this system represents the row state defined validity. Standard uni-temporal solution used today has a lot of disadvantages, which influences the quality. One of the problems is based on the whole state update, which can generate a lot of duplicities. In addition, it cannot provide management for transactions. The first part of this paper deals with the modelling structure for temporal data to improve the performance - size and time consumption. The second one extends the proposed structure, describes the principles, structure and methods for transaction management. The system is fully implemented and temporal transaction oriented.
