Limited by traditional database technology, the spatial data and attribute data were stored dividually. With the transfermation of GIS application to the Distributed Management System, concurrency control, data sharing and network communication become the new problems.

受以往数据库的限制，空间数据和属性数据是分开存储的，随着GIS应用向分布式管理系统领域的转移，在数据共享、网络通信、并发控制等方面出现了许多难以解决的问题。

To solve this problem of keeping date consistence in the heterochronous environment, the paper puts forward a synchronous updating system model, which applied Web Service to capture, store and then transfer updated things in the homogeneous distributed database system and farther implement the system's model of data synchronization, In the design of this model, the concurrency control of distributed things and the method of failure inspection are discussed and solved successfully.

针对异构或异质环境下保持数据一致性的问题，给出一个在分布式异质数据库中，通过Web Service技术，对数据库更新事务进行捕捉、存储后转发，进而实现数据同步更新的系统模型。

However, current WSN applications in Precision Agriculture all adopt the traditional client/sever model, data are sent from the source to the destination, because of hugeous data, high concurrency and strong signal interference in Precision Agriculture and the extremely limited sensor network resources, such client/sever model hampers WSN applications in Precision Agriculture.

然而当前无线传感器网络在精细农业中的应用都采用传统的客户/服务器模型，数据从源端发送到目的端，受精细农业中数据量大、并发性强、信号干扰强及传感器网络资源极端受限的影响，这种客户/服务器模型阻碍着传感器网络在精细农业中应用，导致了当前传感器网络大规模成功应用于精细农业的例子很少。

Oracle automatically uses the lowest applicable level of restrictiveness to provide the highest degree of data concurrency yet also provide fail-safe data integrity.

Oracle 会尽可能地减少锁产生的影响，从而最大程度地保证数据的并发访问能力，并确保数据一致性及错误恢复。

This paper introduces the concepts of CSCW, describes the present state and discusses the problems to be solved, primarily focusing on human computer interaction, concurrency control and collaboration management. According to the research on cooperative characteristics of user actions in CSCW systems, this paper proposes a software architecture model of cooperative systems, Arbor. Its main contents include: Layered structure The Arbor model divides a cooperative system into five layers according to functional decomposition: device layer, concept layer, intention layer, cooperation layer, and computation layer. It deifies user actions and reifies the results of the actions to implement multi-level collaboration among multiple users. Multi-level collaboration obtains finegrained collaboration of the cooperative system and improves its collaboration efficiency.

本文首先介绍了计算机辅助协同工作的基本概念，着重从人机接口，并发控制和协同管理等功能方面介绍了协同系统的现状及其软件结构存在的问题，然后，基于对协同系统中用户动作的协同需求和协同特性的研究，针对目前协同软件系统存在的问题，提出了一种协同系统软件结构模型Arbor，它的主要内容包括：层次结构 Arbor模型从功能上将协同软件系统分为五层：设备层、概念层、意图层、协同层和计算层，它通过对用户动作的多层抽象和对动作结果的多层例化，实现多用户之间的多层次协同及感知，层次结构增强了系统的灵活性和适应性，方便了系统的开发，同时，多层次协同的方法获得了细粒度的协同感知，提高了协同效率。

The implementation method of the hierarchical operation model, including the assistant agent's implementation architecture, the deposition scheme and access and concurrency control of the shared objects, and the system communication structure, is also discussed.

本文还讨论了这种层次操作模型的实现方法，包括助手agent的实现结构，共享对象的存放及存取和并发控制，以及系统通信结构等。

Other topics, outside the scope of this paper are versions, data update problems regarding the shared schemas, optimization of distributed query pro- cessing, transaction management and distributed concurrency control that are subjects of forthcoming papers.

其他主题范围之外，本文版本、数据更新问题对于共享模式，优化的分布式查询亲分布、交易管理、分布式并发控制，即将来临的论文主题。

Berkeley DB offers many of the storage services transactions, concurrency, andrecovery of relational database engines. It is closer to a file system in that it storesany kind of data in any format, but provides no easy tools for ad hoc queries.

Berkeley DB 提供许多存储服务-事务，并发，恢复，这些关系型数据库引擎，更贴切的说它和文件系统很相近，因为可以任一种格式存储数据，然而没有提供很简单的工具在 ad boc 查询的时候。

Graph grammar turns out to be aformal tOOl much more suitable than other formalisms to specify such kink of concurrency and dynamic characteristics.

面向对象的并发系统与传统的并发系统(如用CSP或CCS所描述的系统)的不同之处在于其进程结构的动态性，系统中的进程以及进程之间的通信链路随着对象的变化而动态地建立或撤消。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
