The Design And Application Of Bank Information Data DAS System

As the business scale of commercial banks constantly raised large,they have more and more customer information and transaction data,and how to manage and analyze these data quickly and efficiently is vital to the development of banking business in the future.Aiming at the demand of diversification,I design bank transaction information data collection system in this paper for bank development and operation of basic data platform.In this paper,I research the bank basic data platform and the characteristics of the data source,then I put forward the improving method of the data acquisition mode aiming at the shortcomings of the existing data collection way to achieve fast and efficient information data collection,reducing the time of data transmission and improving the server performance.First,demand analysis is carried out on the bank information data collection system.In view of the system construction goal,this paper introduces the concept of information data,situation and construction target,system architecture and technical characteristics,then it analyzes the functions of DAS information system requirements,environmental requirements,system use case requirements,interface style and the overall performance of the system,and it sets up the bank information processing process.This paper also presents a bank information data acquisition system of the on-line analytical processing strategy,which solves the existing problems of data collection way as low efficiency and time consuming,and as a whole to improve the efficiency and timeliness of data transmission.This paper presents a way of multi-process and multiplexing mode based on the process model to improve the bank transaction log information concurrency and stability of the data acquisition system.And it presents a multiple master process between load balance methods,so the request evenly distributed in more than one master work process so as to lift from the performance of DAS system.Finally,this paper designs a data buffer queue.Based on the classic producers and connsumers thought,it solves the producers and consumers with the problem of synchronization and rate,and it solves the problem of data loss at the same time of preventing data pipeline rupture.And by using signal processing mechanism,this paper implements the DAS configuration file and upgrading of smooth dynamic load function,so as to achieve work 24 hours a day.This paper presents a dynamic adjustment method configuration file by parsing the configuration file to dynamically adjust the parameters of the system to improve the flexibility of the system.On the basis of the study,this paper designs the prototype of data bank information DAS system,and it puts forward with practical and effective technical solution.Through the performance test,the technical solutions on time and performance can meet the demand of bank data collection of basic data platform.Bank information data DAS system meets practical needs of bank information data processing,and it is helpful and practicality in information data processing of the bank.
