Design And Implementation Of LKJ Based Data Management System Based On SOA

As an important component of the railway data monitoring system, LKJ basicdata is the foundation of train control system function realization, and it is also thebasis of locomotive operation, locoman operation, route planning and post analysis.However, due to the current lack of basic data processing optimization and long-termbusiness overlap, there are many problems in the management of railway LKJ basicdata, such as isolated information, poor interaction. On this basis, the LKJ basic datamanagement system not only can meet the future needs of the railway basic databusiness development, but also has very important reality significance.First, the current status of domestic railway data informationization constructionis described in this paper. Analyzes the real problem of basic data management in ourcountry, and explains the purpose and significance of the management systemconstruction.Second, the software design concept and necessity are discussed, and design theservice for system development on this basis. While the Web Service technology hasbeen outline briefly, it can be very helpful to provide a solid technical foundation forthe modules integration of system development and function implement. The systemrequirement analysis includes rail business role and basic data mainly, and highlightsthe characteristics of the system design, also in line with "software business drivenservice", the design concept of SOA.Next, the frameworks of system and system level design based on SOAhave been proposed in the general design. Services interaction is achieved by WebService. The system business process is designed in detail, basic data management hasbeen further improved. The system database design and the specific deploymentmainly take the distributed planning thought. Design principles are required accordingto the data characteristics, and design the entity data model.Finally, this paper demonstrates function design and software developmenttechnology through the preliminary implementation of LKJ based data managementsystem platform, mainly concentrated in the implementation of business processmanagement and basic data management. The testing of system mainly adopts thefunction test and pressure test, according to the test results and system optimizationmeasures summary, put forward the direction and content of next step improving work, further research based on existing technology.
