Abstract


With the rapid development of Internet technology, the various enterprise business is growing, increasing the amount of data processed, and gradually formed a massive data environment, the most typical example is the banking industry. Bank the amount of data continues to expand in recent years, more and more complex data types, banks urgently need to use the new architecture and new technology to improve the efficiency of processing huge amounts of data as well as to improve the flexibility of data processing. If only up from the hardware to improve the efficiency of the system will cause the increase in the cost and waste of resources. Therefore, through the study of massive data query optimization strategy to optimize the system performance of banking is very necessary. Since the advent of the IBM mainframe favored by massive data system. IBM host applications most extensive banking, many large domestic and foreign banks have been the first to achieve data centralization, its core system running on the host platform, but the efficiency of data processing problems caused by the massive amounts of data need to be resolved to become Bank a new system to speed up the construction of information technology. In order to improve the efficiency of mass data processing, relational database performance tuning ongoing, but could not have a centralized platform to provide real and vast amounts of test data, and not be able to make a more comprehensive study. Based on the above background, through self-development and design, and query optimization strategy based on host-based banking system. A three-tier framework of the banking system as a whole of host-based design, and design a good user interface and programming interface. A detailed analysis of each of the major business processes of the Bank, COBOL, CICS middleware, JCL job control language and DB2 database to achieve the key modules of the system. Points query optimization program, including the database physical design optimization, optimization of the query path, as well as the optimization of the program and the program in the system can be achieved through analysis of system performance bottlenecks in this article. Finally, we designed a massive data generation method to generate large amounts of data to simulate real Bank of massive data environment to test the performance before and after optimization banking system through manual testing and automated testing, and before and after comparison is given to prove the feasibility of the optimization program and effectiveness.
