(1) Such a system requires concurrency control and recovery mechanisms.

(2) The concurrency control strategy of drawing archive data based on transaction language is put forward.

(3) Concurrency control and recovery techniques are used in conventional DBMS's to preserve the serializability and the permanence requirements of database transactions. Sentencedict.com

(4) Optimistic locking is an extremely efficient concurrency control method that guarantees data integrity without placing any physical lock in the database.

(5) And condition - locking, a concurrency control mechanism involving two - phase locking is designed.

(6) A two phase locking two version concurrency control mechanism is proposed and it improves two phase locking. This concurrency control mechanism is divided into two mec...

(7) SQL Server also provides the optimistic concurrency control mechanism, which is similar to the multiversion concurrency control used in other databases.

(8) But while synchronization is primarily a concurrency control mechanism, transactions are primarily an exception-handling mechanism.

(9) A two phase locking two version concurrency control mechanism is proposed and it improves two phase locking. This concurrency control mechanism...

(10) This paper proposes a hybrid optimistic real-time transaction concurrency control method based on high priority two phase locking scheme (HORTCC-SHP2PL).

(11) The concurrency control mechanism and the locking strategies ate illustrated, the recovery mechanism is carried out by means of log.

(12) In this paper, distirbuted transaction, concurrency control and resource request model are introduced in detail. The universal deadlock condition in distirbuted database system is summarized.

(13) Design and realization of communication mechanism and concurrency control mechanism of CoGIS were provided, and the communication interfaces of delivery layer and representation layer were designed.

(14) Methods A nested transaction model and concurrency control algorithm based on locking is introduced.

(15) The multilevel secure concurrency control algorithm base on snapshots and multilevel transaction schedule algorithm based on 2PL and serialization graph are presented.

(16) The concurrency control mechanism and the locking strategies ate illustrated, the recovery mechanism is carried out by mea...

(17) The dissertation makes analysis and discussion of concurrency control method of currently available CSCW system and proposes the concurrent control principle and consistent model of collaborative Dr.

(18) We describe a hybrid concurrency control policy using dynamic timestamp allocation method for distributed database systems.

(19) Operational Transformation, at its core, is an optimistic concurrency control mechanism.

(20) Finally, the performance evaluation of our concurrency control algorithm is given compared with the locking algorithm in the ORION.

(21) Moreover, there are many services that do not have concurrency control at all, which may also lead to inconsistent data.

(22) The work in this paper provides the foundation for further research on mixed real-time transaction scheduling and concurrency control, and processing mixed transactions in actual application systems.

(23) In this paper, the characteristics of cooperative design transaction in open environment are studied, and the current default of distributed concurrency control protocol is analyzed.

(24) For the requirements of engineering design transaction, we present an improving optimistic concurrency control method which is based on the nested transaction model.

(25) Based on the analysis of the disadvantages of the present distributed concurrency control protocol, a concurrency control protocol for cooperative design transaction in open environment was proposed.

(26) ZODB is a robust, multi-user, object-oriented database system capable of storing and managing arbitrarily complex Python objects with transaction support and concurrency control.

(27) Based on the known technologies of MMDB and DRDB, this thesis studies the concurrency control mechanism for business objects in application servers of critical business.

(28) Since Business Process Choreographer executes activities within transactions, concurrent access to shared variables is governed by transactional isolation and concurrency control.

(29) A TCS must be capable of organizing and controlling complex business operations including resource recruitment, business function management, concurrency control, and failure recovery.

(30) On the other hand, in the field of Native XML Databases (NXD) the research concerning the transaction and the concurrency control mechanism is initiated not long ago.
