Research And Realization Of The Middleware For The Bank Information Network

Currently, the Bank Counter Business processing systems are based on open systems, most of them are with Client/Server structure, the clients communicate with servers by many different media. But due to the unreliable networks, and the characteristics of the bank systems, which are related with high volume of data, many nodes, and many important data, sometimes data are lost and changed in the transactions, and this makes the incompleteness and inconsistency between the clients and the servers. By the traditional method-which uses reverse and repeat, it can neither prevent risks nor control risks. This leads to the risk of capital and hurts the reputation of the bank.c, To overcome these shortcomings, this project does research on the middleware to control the data completeness and consistency by lock, automatic confirm/reverse, and transaction checking mechanisms. The lock mechanism is used to control the consistency of data, and the confirm/reverse is used to release the resource from locks. In transactions, the middleware uses 3-step handshake method, asynchronous process and confirm procedure (not the previous reverse table) to ensure the completeness of the transaction. The solution has been used in the metropolitan integrated service network of the China Construction Bank of Heilongjiang . With good results, it makes the transactions stable, promotes the efficiency of processing and the reliability of transactions, and protects the consistency of data between the clients and the servers. By using in reality, we believe this solution is proper for the bank business systems, it can not only reduce the risk, but also cut off the unnecessary resource holding. By the meantime, it can also reduce the cost of development and promote the reliability of transaction management and the efficiency of programs for the future business development. It is a good choice of the solutions for the current environment in China.
