【摘要】：隨著Internet互聯(lián)網(wǎng)技術(shù)的不斷發(fā)展，越來越多的企業(yè)、單位、部門采用信息化技術(shù)手段建立電子辦公系統(tǒng)，數(shù)據(jù)信息呈現(xiàn)出爆炸式增長的趨勢。公安機關(guān)作為國家預(yù)防、制止和偵查違法犯罪活動等維護民眾公共治安的重要部門，其正常運行需要采集大量的社會信息，從而進行分析、做出正確決策。原本各部門建設(shè)的信息化數(shù)據(jù)采集業(yè)務(wù)系統(tǒng)也確實為公安部門的工作提供了便捷。但隨著時間的推移，由于各個部門業(yè)務(wù)系統(tǒng)建立時間不一、建設(shè)團隊不一造成的數(shù)據(jù)冗余、“信息孤島”的現(xiàn)象也漸漸顯露出來。為了使公安相關(guān)部門能夠打破時間、空間限制，全面、準確地獲取到所需數(shù)據(jù)，公安部門開始尋求數(shù)據(jù)集成解決方案。本文與實際工程緊密相連，以四川省公安廳數(shù)據(jù)集成平臺的開發(fā)應(yīng)用為背景，研究如何利用面向服務(wù)架構(gòu)（SOA）技術(shù)，根據(jù)其面向服務(wù)、松散耦合、粗粒度、易擴展等特性，將現(xiàn)有分布多處、數(shù)據(jù)存儲結(jié)構(gòu)各異的公安信息資源集成為一個數(shù)據(jù)源充分獨立、信息相互交叉、易擴展新增數(shù)據(jù)源的公共數(shù)據(jù)平臺。通過對傳統(tǒng)數(shù)據(jù)集成技術(shù)的分析研究，比較其優(yōu)勢劣勢，依據(jù)數(shù)據(jù)集成需要易于擴展數(shù)據(jù)源的新要求，，針對分布式異構(gòu)數(shù)據(jù)集成存在的問題進行分析，主要闡述了公安數(shù)據(jù)集成平臺的SOA架構(gòu)設(shè)計、數(shù)據(jù)抽簽、數(shù)據(jù)整合等環(huán)節(jié)的研究，通過采用數(shù)據(jù)復(fù)制、數(shù)據(jù)快照、全表對比、時間戳等方式集成各數(shù)據(jù)源，并將整合服務(wù)分解為多個服務(wù)粒度更小的轉(zhuǎn)換步驟，在降低耦合的同時，增加系統(tǒng)重用性，建立可重用、易擴展、高效率的公安數(shù)據(jù)集成平臺。
[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.
