Abstract
Modeling, analysis and performance
distributed database concurrency control
concerned in this study.
evaluation of
algorithms are
A general detailed model for concurrency control in
distributed database systems which provides a framework to
study the performance of different concurrency control
algorithms is presented. Performance criteria to evaluate
different algorithms are discussed and prepented.
Analytic queueing models, as well as queueing network
models for different classes of concurrency control
algorithms in distributed database systems, are developed.
These models are verified by simulation .
The computational and simulation results of analytic
and simulation models are studied.
A sensitivity study of performance to environment
parameters and solution is given.
A probabilistic distributed database system analysis,
and mathematical model derivation are given. This includes a
probabilistic model of conflict.
Much insight has been gained in this study about
concurrency control in distributed database system. It is
believed that this methodology, and analytic analysis can
be an example not only for performance analysis and
evaluation of other concurrency control methods but also in
studying other distributed database problems.
