Research And Implementation Of The Vital Technologies In Distributed Data Transfer Of The Banking System

Centralization requires that the function of the new business and system should be integrated with the former distributive system organically.'Information Integration'is not a new topic. However, the'Strategy of Integration'develops continuously with the development of information technology. The traditional'point to point'method of integration can't satisfy the need of keeping pace with the time. In the whole, the banking application integration established on the basis of the unified basic business stage has gradually become the solution of e-commerce for banks of the same trade in the world. In regard of the banking industry, it is now in the inner-informationization construction stage with the primary question of how to organically integrate every links such as planning, managing and serving through software system to realize resource sharing and optimal efficiency. The data exchange stage of the present thesis is an application software stage with the function of transaction switchover used for connection of various business systems in a bank, according to the specific business logic. Acting as the core for the data exchange, the present data exchange stage organically connects the distributive banking business systems to form a whole and therefore realize the abundant and flexible integration of business and information.(1) Application integration on distributed systemThe present thesis makes an analysis on the two connection modes for communication of iso-components with combination of the discussion on data safety and integrity during the integration that drawn extensive attention in the banking industry. It also makes a comparison of the responsibility and lock/release speed of system source of the two connection modes in terms of integrity of transaction, stability of system circulation, consistency of data exchange and single point risk brought by center control. A better solution is selected out. The present thesis has certain instructional meaning for the design and development of integration of finance system.(2) Data integration on the iso-databaseThe present thesis provides a method for analyzing switchover on the basis of the data difference of the iso-distributive system. The present method distinguishes the data structural conflict and definition conflict during the interchange of the iso-system on the basis of data modeling, data reflecting and other theories in combination with the characteristics of data grammar and definition and establishes metadata switchover knowledge data base for translation of interchanged information. Meanwhile, it can make analysis on the distinguishing ability to the information of the iso-systems and work out the solution of storing and transmitting data in the form of VSAM document.(3) Load balance on the data exchange platformOn completion of the information integration and business concentration, the exchange stage has become a joint point in the information interchange. In order to avoid the single point risk and secure the stable operation of the interconnected system, the operational performance of the system should be controlled dynamically. The present thesis improves a process scheduling calculating method on the basis of the treatment ability of junction point and property of mission and other factors taking the theory of load balancing as the fundamental theory so as to effectively balance the load of junction points and improve the responsibility of the transactions as well as reduce the operational risks of banks.The present theis makes the research with the methodology'Theory models vs. Technical Implementation'. First to setup a model base on the investigation of the theories, the data exchage platform, then goes for the technical details. At last, the feasibility and the validity of the model are approved by the cases study on banking's project. The methodoloty used in the thesis could not only be used for the automation on the data exchange platform of the bank's iso-distributed system, but also gives a solution & theoty model for the financial industry. Also, it can be referenced with valued experience in the system intergration process for the other industuies.The present thesis provides an effective method for analyzing and solving the key problems of system connection, data interchange and load distribution in the iso-system information integration in combination with the background theories of load balance, system distinguishing and metadata modeling establishing. With the fast development of the system concentration of banking industry, telecommunication industry, securities business and data concentration, the method raised in the present thesis has certain instructional meaning to the system integration and system construction. Meanwhile, as the advanced model of concentrated system proceeds, the analysis and research made in the present thesis provide a meaningful exploration for the application of large scale.
