Research And Implementation Of SAP Bank And Enterprise Direct Connection Key Technology Based On B2B Block Trading

The traditional chemical sales mode in modern high-speed economic development has a very good performance,a huge volume of business process requires manual supervision and intervention,not only consume a large amount of human resources business efficiency is not high,and too much manual intervention leads to the inevitable errors and error.In view of the above problems and phenomena,this topic introduces the concept of bank enterprise direct connection,develops the self-service card making and settlement terminal system.The terminal combines light mechatronics,automation and computer integration technology.According to the business needs,the terminal system is distributed in the distributed layer,and the business implementation and business logic processing are concentrated in the application layer.When the business rules change,just change the application layer,do not affect the functions and services of other layers,and truly achieve the high cohesion and low coupling of the system.At the same time,the Web Service caching control is improved.According to the caching frequency and the size of the cache object,the priority of each cache module is calculated.Finally,the lowest priority level is eliminated,and the response time of the improved system is significantly reduced.On the issue of data interaction between SAP financial system and bank end,a middleware based three tier architecture mode design is adopted.The middleware is independent of the financial system and the bank terminal communication processing module.The middleware is between the enterprise SAP financial system and the bank end,which is specially responsible for communicating with the bank and uploading the results to the financial system.Considering the different data structure of each bank,the heterogeneous data integration module is added to the middleware in order to shield the heterogeneous data source and generate the data format that the application layer can recognize.This design model can make the enterprise SAP financial system more focused on its own business and hide the enterprise SAP financial system to access the bank side.The complexity of it.It effectively relieves the financial system business pressure and improves the business efficiency of the financial system.The system function and performance test results show that the terminal system can achieve a stable and efficient business card making and settlement business without manual intervention,and reduce the waiting time.The financial system can communicate with the bank and the bank.At the same time,the efficiency of business processing is greatly improved.At present,the system has been applied to actual business sales.
