    ABSTRACT

    In recent years, e-commerce, social networks, and mobile smarttechnologies have continued to advance, and society has entered the dataage.' The data resources on the computer and mobile terminals have becomethe core resources and core competitiveness of the enterprise. Therefore,make full use of these data resources to conduct statistical analysis of userbehaviors, absorb data in formnation through intuitive numbers or trendcharts, and improve service value and assist management. The decision ofthe people at the level has become a top priority. However, existing dataanalysis systems have the disadvantages of complex heterogeneous dataintegration, inability to read and encode, and low efficiency of datatransmission. In response to these shortcomings, this paper designs andimplements a Java Web-based data analysis system.

    This paper analyzes the background and significancethe research  status of predecessors, studies the key technologies needed for system  development, designs and implements a data analysis system in order to  collect, analyze and visualize the data. According to the software  development life cycle process, combined with Java Web framework   Quartz, Message queue Kafka, Zookeeper and so on, from the system  feasibility analysis, module requirements analysis to the design of each  functional  module business  logic,to the  specific  coding implementation,we complete four modules: data collection, data transmission, data analysis and data visualization, and carry out black box testing for system functions, performance, and security.

    At the same time, in order to realize the unified collection, extraction  and organization of information, this paper designs and encodes a common  message body based on data dictionary to solve the complex problem of heterogeneous data integration. The message retrieval algorithm in the  message queue is studied, and the improvement is based on the ordinary  binary search. The step of cutting from the middle is replaced by the  distance difference from the evaluation, and the algorithm is implemented  to solve the defect of low data transmission efficiency. Then, the  performance of the improved message retrieval algorithm and the existing  algorithm are compared from mathematical reasoning and number of times  of searching. Finally, in mathematical reasoning, the improved algorithm  reduces the time complexity. In the number of searches, the number of  searches is reduced, the search time is greatly reduced, and the efficiency  is more efficient. Finally, the existing system message types are not easy to  read and encode using text, string, XML, etc. The system uses a lightweight  data exchange format JSON JavaScript Object Notation to encapsulate  information, reducing the performance of parsing and compatibilty issues.

    KEY WORDS:data analysis, software development life cycle, common message body,message retrieval algorithm
