Design And Implementation Of Internetwork Data Exchange System Based On Workflow

In recent years,all domestic industries have formed a network system with a proprietary network as the core.In military enterprises,internal information systems and networks contain a large amount of information and data concerning state secrets,but in order to ensure the smooth development of the business,there will be A large amount of data needs to be exchanged between real-time or non-real-time data between networks.Therefore,through the development of a feasible network data exchange system,it has important practical significance for realizing data exchange between internal and external networks.This paper develops a workflow-based network data exchange system for the data exchange requirements of a space research institute.This system not only realizes the five types of data exchange process required by the national secrecy standard,but also satisfies the daily scientific research and production management of the institute.The actual business needs in the process.This paper is based on the design and implementation of workflow-based data exchange system.Around this topic,we first collect and organize a large number of relevant research results,which provides a solid theoretical support for the design and implementation of the system.Then,according to the actual business needs,the requirements analysis is carried out,and the architecture of the system is subdivided and disassembled.The management subsystem,file exchange application and supervision subsystem and file exchange subsystem in the workflowbased internet data exchange system are designed respectively.,intermediate conversion subsystem and Internet exchange subsystem;and detailed use case diagrams and flow charts are designed around different subsystems,which determine the direction for the division and design of the next system module.According to the requirements analysis,the design of the system module is carried out,which mainly includes the system management subsystem,the file exchange application and supervision module,the security and security module,the design error processing module,and the functional design and performance design of the database.The system is based on J2 EE architecture,adopts JAVA language technology,uses Browser/Server(browser and server)mode,database uses Mysql,and establishes a workflowbased internal and external network file exchange system to form a safe and controllable A data exchange platform enables the inter-network switching system to be implemented.The user can use the browser to initiate data exchange application.The indexer uses the subsystem to centrally perform data exchange operations.The administrator completes the supervision and auditing through the background exchange process,and divides different authorization management for users,organizations,and authorities to realize the subject-to-person.The security management mechanism of the object to the information category ensures the security of the data exchange process and forms the lifecycle management of the data exchange process,which can meet the requirements of various standards for confidential assessment and certification.Finally,the test part of the whole system,including functional test and performance test,the test results show that the system can realize five business processes of non-closed export,confidential export,non-close import,confidential import,and internal data transfer.Supported,tested and verified,the system can meet the business needs and performance requirements,while meeting the relevant national standards of confidentiality,achieving data exchange capabilities and work efficiency between the internal and external networks.
