Performance evaluation of two concurrency control protocols for distributed databases with multiversioned entities

Proceedings. Fourth International Conference on Data Engineering, 2003
The authors evaluate and compare the performance of two concurrency control protocols for distributed databases with multiversioned entities, assuming that each transaction incrementally declares its access set from the successive parts of the preordered entities. The first protocol is called protocol proposed (PP).

Concurrency control by transactions carrying states and preordering universioned entities

Proceedings of the 1988 ACM sixteenth annual conference on Computer science - CSC '88, 1988
Abstract We present a protocol for improving concurrency and preserving consistency in databases with multiversioned entities; the database can be either centralized or distributed and may or may not have data replication. In the proposed protocol, entities are assigned an order, and whenever possible each transaction accesses entities in this order;

A new multiversion concurrency control algorithm for partial update transactions and bulk retrieval transactions

Systems and Computers in Japan, 1992
AbstractWith the advanced use of databases, on‐line and batch transactions are executed concurrently. Then a demand arose for the concurrency control method which can realize the excellent on‐line transaction processing independently of the batch transactions. The multiversion concurrency control is suitable for such a requirement.This paper proposes a

A Dynamic Overwrite Protocol for Multiversion Concurrency Control Algorithms

1991
The main difficulty with multiversion database systems is that of storage space, i.e. in a multiversion database we would need to keep a potentially unlimited number of versions of data items. As storage space is always limited, the number data item versions maintained in the database is also limited.
