Research And Application Of Hadoop Architecture In The Government Procurement System

The reform of the domestic government and the continuous improvement of the procurement system has promoted the continuous improvement of the government procurement work,but there are still outstanding issues such as system resources and data sharing.Distributed cloud computing technology has a more prominent advantage for mass data storage and processing,which is conducive to the realization of resource sharing and data processing.It is a good solution to solve the problem of government procurement.In this paper,through the analysis of the existing government procurement system,the paper puts forward the construction of government procurement system based on Hadoop platform.In this paper,we study the implementation process of data access and processing of government procurement in Hadoop platform,and design and implement the system's overall structure,function module and database.After testing,the system achieved the desired functional requirements and performance requirements,and through the test to verify the Hadoop platform to meet the needs of government data processing.The main work of this paper is summarized as follows:1.Summarize the current government procurement background,analyze the current situation and the existing problems of government procurement,in addition to the implementation of the system of the project background in-depth analysis.2.In-depth study and analysis of the Hadoop platform for mass data storage and processing of the work,at the same time,with the actual government procurement business process,analysis of the Hadoop platform used in the government procurement system to deal with the feasibility of procurement data.3.With the current problems of the government procurement system,the construction needs of the system in terms of data processing and function,and the system architecture design and function design.Among them,the focus of the design and use of the Hadoop platform to access the database and the process of purchasing business data processing.4.The government procurement prototype system is developed.The function test,stress test and application performance test of Hadoop platform are carried out.
