Design And Implementation Of The Communication Middleware Of Bank

There have been a great amount of research and appliance aboutdatabase and middleware technology inside or outside of our nation inrecent years, and the technology is improving to perfect with the timegoing on, For the reasons above, traditional operations of bank havechanged from majorities of manual operations to computer automation,and run as the pattern of networks, in which not only profit isincreased, scale is enlarged, operations becomes transparent, but alsoprovide convenient for customers.In this paper we carry a lot of research on middleware technologyand data-dictionary technology at first, to provide an advanced datadictionary based on bitmap which is designed to restore thecommunication messages. Then combine the above two kinds oftechnologies to give a new thought of adopting the middlewaretechnology to build Agent-Service platform of bank. At last a newimproved communication platform of bank which is based on tablepropelling technology is introduced in this paper ,namely IntegrativeFront-banking System, and its' role and priority ,also the constructionof hardware , then the Design and Implementation method in UNIXoperation system in object-oriented mode. The main works of thispaper including:1. Designed and realized the Agent-Service platform whichadopted middleware technology-Integrative Front-banking SystemThe platform of Agent-Service is a platform which is designed inview of the merits of database management and middlewareapplication, and it is a middleware platform based on bitmap-datadictionary communication. In this system, we took INFORMIXdatabase as our database;and high proficient C language as ourprogramming language;the communication technology is SOCKETtechnology based on TCP/IP protocols, which made our middlewaresystem beyond the restricts of operation system and network structure,and which realize the span agent service operations among operationsystem platform and regions;On the other hand the server run inUNIX operation system which assured security. It can satisfied thedemand of customers as well as services of many kinds of demands.2. Realized the platform of Agent-Service which is based on tablepropelling technology of bankThe increment operations of bank system are dynamic operations,with time going and improvement of social service, there must be aincrease in type and an enlargement in pattern. So it is often needmodify and increase to the system at any time. In order to meet thedemand above, Integrative Front-banking System must conform to thethink of modern programming, namely the OOP technology must beadopted, and for sake of the convenient of addition and modify, it hadadopted a new advanced table-propelled technology, that is to say,allsystem running parameters such as running,stop,managing processand inputting and modify of operation parameters were all realize bytables, new operations' inputting only need to ajust the trasactiontables and system tables. there is no need to modify the program inorder to modify operations, the only needs is to modify transactiontable items. All agent services operations can all be added,deleted andmodify in this system through modify table item, which make it areality that once development and long term profit, which also largelyproved the invest cost of bank.3. Resolved the problems of security and data integrity andconsistencyThe bank operations are related to everyone, the data's integrity,consistency and security are the most important. There need someprotective measurements to keep data in integrity and consistency,Integrative Front-banking System adopt many methods such asinternal check of data format,stream record,automate modification,day-end proofread,trade log recording and etc, and adopt semaphoreto protect mutex resource, and atomic transaction processing to protectdatabase to ensure that the data of customers and agents are consistentand integrative. In security aspect, Many encrypt strategies are tokenin several to prevent from ill destroy. In this system we adopted theencrypt mode of combination of software and hardware encryption.Many kinds of software encryptions algorithms such as DES,tripleDES,RSA,RC4 etc, and free granularity strategies in encryptionsensure the security of customer's data.
