| 1 | Design and development of real-time query platform for big data based on hadoop显示文摘This paper designs and develops a framework on a distributed computing platform for massive multi-source spatial data using a column-oriented database(HBase).This platform consists of four layers including ETL(extraction transformation loading) tier,data processing tier,data storage tier and data display tier,achieving long-term store,real-time analysis and inquiry for massive data.Finally,a real dataset cluster is simulated,which are made up of 39 nodes including 2 master nodes and 37 data nodes,and performing function tests of data importing module and real-time query module,and performance tests of HDFS's I/O,the MapReduce cluster,batch-loading and real-time query of massive data.The test results indicate that this platform achieves high performance in terms of response time and linear scalability. | 刘小利 Xu Pandeng Liu Mingliang Zhu Guobin | 2015 | High Technology Letters2015，21，2： | 1 |
| 2 | Digital Mock-up Technology in Product Development and Research显示文摘After introducing the present status of digital mock-up (DMU) technology in product development and research,the modeling and its key technologies in product design are described. The architecture of digital design platform system for main DMU model is developed. Based on the architecture,a method of skeleton design has been applied to the development of digital design system. | CHEN Xu,ZHANG Pandeng,YANG Cheng,XU Zhongming (College of Mechanical Engineering,Chongqing University,Chongqing 400044,China) | 2006 | 武汉理工大学学报2006，28，S1： | 0 |
