The container provides automatic support for managing things like resources, transactions, and concurrency but can also introduce substantial overhead in your applications.
该容器为管理资源、事务和并行性之类的内容提供了自动支持，但是也会为应用程序引入大量负载负荷。
Determine if this is appropriate for your needs, and also consider how the scope (and isolation level) you define for your transactions can impact overall concurrency requirements.
确定这是否适合您的需要，还要考虑您为事务定义的范围(和隔离级别)将如何影响整体并发需求。
Always starting transactions at the highest level in the call stack (the API layer) can be inefficient, particularly in cases of high-user-throughput and high-database-concurrency needs.
始终在调用栈的最高层(api层)启动事务有时会效率低下，特别是对于具有高用户吞吐量和高数据库并发性需求的应用程序。
Many concurrent users perform numerous transactions that require rapid access to data. Availability, speed, concurrency, and recoverability are key issues.
许多并发用户执行大量需要快速访问数据的事务。可用性、速度、并发和可恢复性是主要关注点。
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.
本文的研究成果为进一步探讨混合实时事务的调度与并发控制，以及实际应用中的混合事务处理提供了良好的基础。
The paper focused on concurrency control mechanism of mobile transactions and proposed a concurrency control strategy based on dynamic timer.
文中着重研究移动事务的并发控制机制，提出了一种基于动态计时器机制的并发控制策略。
This paper presents a model for object -oriented distributed transactions, and proposes the concurrency control algorithm that fits this mode. In this paper, the algorithm has been proved.
本文给出了一个面向对象的分布式事务处理模型，提出了适应此模型的并发控制算法，并对算法的正确性进行了证明。
Concurrency control and recovery techniques are used in conventional DBMS's to preserve the serializability and the permanence requirements of database transactions.
在传统数据库管理系统中，采用并发控制和恢复技术来保证数据库事务的可串行化和持久性要求。
Mobile update transactions and mobile read only transactions are supported by a pseudo serializable concurrency control protocol that supports both updates and read-only transactions from clients.
为在广播环境中同时有效支持移动更新事务和移动只读事务，提出一种可在移动客户端同时支持更新事务和只读事务的伪可串行化实时并发控制协议。
Moreover, conventional concurrency control and scheduling methods for update transactions are not suitable in that mobile real-time transactions are complicated and nested.
而且，由于移动实时数据库系统中大多数事务都是复杂的嵌套事务，传统调度策略都已不太适用。
