Chanjung Park, Seog Park, S.H. Son
2002 IEEE Transactions on Knowledge and Data Engineering  
Database systems for real-time applications must satisfy timing constraints associated with transactions.  ...  In this paper, we propose a new multiversion concurrency control protocol that ensures that both security and real-time requirements are met. The proposed protocol is primarily based on locking.  ...  ACKNOWLEDGMENTS This research was supported in part by the Brain Korea 21 Project in 2001.  ...
