Abstract: |
This paper considers some
opportunities of the system for simulation modelling
GPSS World Personal Version for simulating algorithms for transaction
concurrency control (CC) in Distributed database management systems (DDBMS).
Models of Timestamp ordering (TSO) algorithm and Two-version Two-phase
locking (2V2PL) in DDBMS are presented. Both approaches – two version data
and timestamps (and others) are used in database management systems for
avoiding transaction deadlock. Method of TSO and method of 2V2PL are still
not investigated enough. However, the use of timestamps makes the CC
algorithms more complex due to the restarting of the transactions from service
and the additional waiting for processing. Therefore results of the
implementation the simulating algorithms are showed in comparative view. |
