【摘要】：随着Internet互联网技术的不断发展，越来越多的企业、单位、部门采用信息化技术手段建立电子办公系统，数据信息呈现出爆炸式增长的趋势。公安机关作为国家预防、制止和侦查违法犯罪活动等维护民众公共治安的重要部门，其正常运行需要采集大量的社会信息，从而进行分析、做出正确决策。原本各部门建设的信息化数据采集业务系统也确实为公安部门的工作提供了便捷。但随着时间的推移，由于各个部门业务系统建立时间不一、建设团队不一造成的数据冗余、“信息孤岛”的现象也渐渐显露出来。为了使公安相关部门能够打破时间、空间限制，全面、准确地获取到所需数据，公安部门开始寻求数据集成解决方案。本文与实际工程紧密相连，以四川省公安厅数据集成平台的开发应用为背景，研究如何利用面向服务架构（SOA）技术，根据其面向服务、松散耦合、粗粒度、易扩展等特性，将现有分布多处、数据存储结构各异的公安信息资源集成为一个数据源充分独立、信息相互交叉、易扩展新增数据源的公共数据平台。通过对传统数据集成技术的分析研究，比较其优势劣势，依据数据集成需要易于扩展数据源的新要求，，针对分布式异构数据集成存在的问题进行分析，主要阐述了公安数据集成平台的SOA架构设计、数据抽签、数据整合等环节的研究，通过采用数据复制、数据快照、全表对比、时间戳等方式集成各数据源，并将整合服务分解为多个服务粒度更小的转换步骤，在降低耦合的同时，增加系统重用性，建立可重用、易扩展、高效率的公安数据集成平台。
[Abstract]:With the continuous development of Internet technology, more and more enterprises, units and departments use information technology to establish electronic office systems, and data information shows an explosive growth trend. The public security organ, as an important department of the state to prevent, stop and detect illegal and criminal activities, needs to collect a large amount of social information to make correct decision. The information-based data acquisition business system built by various departments has indeed provided convenience for the work of the public security department. However, with the passage of time, the phenomenon of "information island" is gradually revealed because of the different time of establishing business system and the data redundancy caused by the different construction team. In order to make the public security departments break through the time and space constraints and obtain the required data comprehensively and accurately, the public security departments began to seek a solution for data integration. Based on the development and application of the data integration platform of Sichuan Public Security Bureau, this paper studies how to use the service-oriented architecture (SOA) technology according to its characteristics of service-oriented, loosely coupled, coarse-grained, extensible, and so on. The existing public security information resources with multiple distribution and different data storage structures are integrated into a public data platform with independent data sources, intersecting information, and easy to expand new data sources. Based on the analysis and research of traditional data integration technology, the advantages and disadvantages are compared. According to the new requirements of data integration, the problems existing in distributed heterogeneous data integration are analyzed. This paper mainly expounds the SOA architecture design, data drawing and data integration of the public security data integration platform. By adopting the methods of data replication, data snapshot, full table comparison, time stamp, etc, the data sources are integrated. The integrated service is decomposed into several transformation steps with smaller service granularity, which can reduce the coupling, increase the system reusability, and establish a reusable, extensible and efficient public security data integration platform.
