61 Study on Process Modeling and Concurrency Technology of Product Design and Process Plan. 62 The multilevel secure concurrency control algorithm base on snapshots and multilevel transaction schedule algorithm based on 2PL and serialization graph are presented. 63 There are four isolation levels in DB2 to control concurrency. 64 The concurrency control mechanism and the locking strategies ate illustrated, the recovery mechanism is carried out by mea... 65 Since Business Process Choreographer executes activities within transactions, concurrent access to shared variables is governed by transactional isolation and concurrency control. 66 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. 67 Air defense weapon system is a complex system, it is characterized with synchronism and concurrency. 68 The preliminary result shows, that the two-phase locking protocol can do well for supporting the transaction concurrency in XSQS. 69 A TCS must be capable of organizing and controlling complex business operations including resource recruitment, business function management, concurrency control, and failure recovery. 70 We describe a hybrid concurrency control policy using dynamic timestamp allocation method for distributed database systems. 71 Based on flow - control's discreteness, configure, affair and concurrency transacting , one application is organized perfectly . " 72 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. 73 Operational Transformation, at its core, is an optimistic concurrency control mechanism. 74 The new line set up makes possible to keep the overall consumption below 300 m. a record in its class! improving this figures by 10 to 20% with respect to the other concurrency wings. 75 Finally, the performance evaluation of our concurrency control algorithm is given compared with the locking algorithm in the ORION. 76 The paper focused on concurrency control mechanism of mobile transactions and proposed a concurrency control strategy based on dynamic timer. 77 In order to maintain the consistence of shared design objects, system adopts user roles management, concurrency control and synchronization mechanism. 78 At this point, it's pretty much common knowledge that past a certain level of concurrency doing I/O asynchronously vastly outperforms synchronous I/O in separate threads. 79 Abstract: A locking - based concurrency control scheme fo r object - oriented databases ( OODBs ) was presented. 80 The concurrency decreases and data integrity increases when you move the isolation level from uncommitted read (UR) to repeatable read (RR). 81 A concurrency control algorithm based on the transaction conflict graph is proposed. 82 The mechanism not only makes user to get query result quickly, but also enhances the concurrency of update transaction. 83 Deadlock detection and prevention of transaction are very important to concurrency and integrity in database systems. 84 The Concurrency Runtime is a concurrent programming framework for C ++. 85 The Concurrency Runtime simplifies parallel programming and helps you write robust, scalable, and responsive parallel applications. 86 The CCR addresses the need of service-oriented applications to manage asynchronous operations, deal with concurrency,[http:///concurrency.html] exploit parallel hardware and deal with partial failure. 87 Many of our languages are dependent on fragile concurrency mechanisms, like threads with shared state, or possibly worse, a global lock that limits execution to a single thread on a single core. 88 This paper analyzes the property of PDM and a nested transaction model which can improve concurrency of two phase locking mechanism. 89 Introduce concurrency control method based on transaction instance lock set and posterior sub-transaction type set. 90 One of its interesting features is the actor-based concurrency support that is modeled after the Erlang programming language.
