事务处理

The complementary of the Web service function is also critical due to the development of the Web grid computation.

Web网格服务环境下的事务处理与传统分布环境下的事务相比，有其特殊性。

In this paper,Intranet system model is designed based on component transaction server.This model can satisfy the power supply bureau＇s need of massive transaction processing and real－time data access and operation.

文章描述了基于组件事务服务器的Intranet系统模型设计过程，这种模型可以较好地满足电力局所需的大规模事务处理和实时数据访问与操作的需要。

Synchronous transactions often use remote procedure call, RPC to deal with distributed applications.

同步事务处理通常采用远程方法调用来处理分布式应用。

The features of transaction in multidatabase systems are analyzed, and the necessity to keep the global serializability when concurrency control of transaction processing in multidatabases is emphasized.

分析了多数据库系统中事务的特征，指出多数据库事务处理的并发控制问题需保持全局可串行化，即要求在各局部场地局部事务的执行不违反全局的执行次序。

Global transaction management Global transaction management consists of global serializability, global atomicity and recovery, global deadlock checker, etc. In distributed data resources management, the complexity of local data sources increases the difficulty of global transaction management.

分布数据资源管理中的全局事务管理通过对事务管理的关键问题的分析，针对分布数据资源管理中数据源在事务处理能力中的巨大差异，提出了给每一个局部数据源包装器添加一些事务处理的功能，让包装器针对特定数据源的具体情况完成部分全局子事务的并发控制和恢复管理，使得在全局管理层可以使用二阶段锁进行并发控制和使用二阶段提交进行事务恢复，并使用超时法进行死锁检测，从而达到分数据资源的全局事务管理。

In addition, a new synchronization scheme, Double-Timestamp Transaction-Level Synchronization model is put forward to solve the synchronization problem under the 3-tier replication architecture (Mobile Client - Synchronization Server - Database Server). DTSTLS utilizes a novel double-timestamp strategy to promote the efficiency of synchronization. Besides, it ensures serializability and consistency of the mobile database system through transaction-level conflict reconciliation.Mobile transaction processing is another key technology to provide efficient information service in mobile computing environment.

通过引入一种乐观并发控制方法与两段锁协议相结合的移动事务处理机制，本文重点解决了交互式长事务的问题，并提供了对移动主机任意移动性和数据库系统一致性的支持；在移动对象数据库方面，本文提出了一种新的移动对象数据库模型—离散时空轨迹移动对象数据库模型，重点阐述了DSTTMOD模型中的位置表示方法及位置更新处理策略，并分别给出了基于GRID文件和基于QUAD树的移动对象索引算法。

The collocated transaction can insure of efficient and correct work and it has lock and time impression control models.

分布式的并发事务处理能保证事务的高效正确的进行，它包括锁和时间印两种控制模型。

The basic method of data restoration from the view of the transaction processing and daily record was expatiated on.

本文从事务处理和事务日志的角度阐述了数据恢复的基本方法。

In this paper,we present the general concept and technology in distributed transaction processing and analyze its popular standar...

文章简要介绍了事务处理的基本概念与一般技术，并详细分析了当前流行的分布式事务处理标准。

The business logic, mesosphere, to become the kernel at processing transaction since the three－layer architecture lodged, and it become to the main storage process because of independent from data storage layer.

EJB是商业逻辑层的构件技术，他提供了事务处理的能力，自从三层体系结构提出，中间层，也就是商业逻辑层，是处理事务的核心。由于从数据存储层分离，他就取代了存储进程的大部分地位。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
