System Architecture Based On Three-tier SOA Model And Modeling Platform Design

Development of systems experienced process of structured object-basedmodel, components model and SOA model, by studying their advantages anddisadvantages, combined with Workflow technology the features of a gooddivision of tasks and control, introducing logic layer on the basis of traditionalSOA model, building a three-tier model based on SOA from the perspective ofthe business. Compared to traditional systems development methods based onstatic models, the model can get more space in their ability to solve the rapidexpansion of business rules and deal with risks, support applications system ofinnovative business demand.Proposed a new framework support fast, smooth, reusable applicationdevelopment based on SOA dynamic model. The architecture is based on thethree-tier model of SOA, complete the analysis of the composition of business,the LL7(application layer Language) of Business processes and the extract ofthe corresponding components and the completement of the design of theprocess engine with reference to the sequencer. the write-only bus linked thecomponents to the processes engine in the underlying design of the architecture,Process Engine calls for each components in the form of messages, eachcomponents feedback to the process engine the result in the form of messages packaged after completing specific operations, Operation among componentsoperate alone, and parallel processing can be realized.Complete modeling platform for the application system architecture,Realization of SOA Three-tier modeling work. completed conceptual modeling,logical modeling and physical modeling respectively, for specific applications,conceptual Modeling implements the division of concepts and the affiliationsexpressing, logical modeling achieved the formalization and definite statementsof business processes, and corresponds the control of workflow engine to thebusiness process to instructions. Physical modeling achieved the extraction,named and unified management of the component, Determine the compositionof the components in the underlying implementation, Finally, the modelingplatform took bank card business for example, achieved conceptual modeling,logical modeling and physical modeling respectively, The results show that thesystem development framework has good ability of BPR, Ensure sustainable andstable of business systems, and the modeling platform enables the demand forSOAthree-layer modeling.
