Based On The Departmental Level Public Security Police Of The Soa, Collaborative Oa System Design And Implementation

SOA-based OA information system is the focus of construction of Tibet Public Security Bureau.While the Tibet Public Security Bureau of computer hardware is very good under the impetus of the Golden Shield Project,But,the computer software application is poor compared with the Mainland provinces and cities.In this paper,through the analysis way of existing office,summarized shortcomings of the existing office systems,derived demand for new office system.Principles and key technologies for in-depth study to identify new approaches in Administrative Office,reduce the time and improve speed in OA,allow police officers to office in the network.SOA has had a profound impact on modern software model,the SOA through service,discovery,binding mechanism for the provision of services.SOA has the characteristics of Loosely coupled and interoperability.Using SOA architecture design ideas to minimize system overhead.With the characteristics of the public security sector and SOA architecture re-establish the full of office automation platform.Using the method of J2EE three-tier architecture,development of robust applications, preferably in a durable layer of loosely coupled with the general API. The pattern of DAO encapsulates database, access operations used to create a simple component,So that programmers do not have to care about the internal implementation method.You can configure different persistence mechanism and reducing the number of modules with the factory pattern.The purpose of project is to promote the process of building the public security information technology.
