Temporal and real-time databases: a survey

G. Ozsoyoglu, R.T. Snodgrass
1995 IEEE Transactions on Knowledge and Data Engineering  
A temporal database contains time-varying data. In a real-time database transactions have deadlines or timing constraints.  ...  In this paper we review the substantial research in these two previously separate areas. First we characterize the time domain; then we investigate temporal and real-time data models.  ...  Concurrency Control Techniques with Serializability.  ...

C3: Concurrency control on continuous queries over moving objects

Jing Dai, Chang-Tien Lu
2010 2010 IEEE 26th International Conference on Data Engineering (ICDE 2010)  
In addition, continuous monitoring combined with frequent location updates challenges the development of serializable isolation for concurrent index operations.  ...  The proposed concurrency control protocol, equipped with intra-and inter-index protection, assures serializable isolation, consistency, and deadlock-freedom.  ...  Therefore, the lack of efficient concurrency control protocols for continuous queries limits the applicability of the moving object management systems in the real world.  ...
