A Brief Introduction Hadoop-based Big Data Query System

CHEN Mengjie;CHEN Yongxu;ZHANG Yichuan;SONG Jie;Software College,Northeastern University;  
In recent years,with the rapid development of computer technology,its area ushers in the era of big data.With the emergence of big data,the traditional relational database connot meet the needs of high storage capacity when the low cost cloud database with good parallelism and scalability comes into being at the historic moment.It uses a Key-value data model and the distributed computing environment. But the problem that query of huge amounts of data in the Key-value database lacks efficiency and has bad real-time performance is universal. To solve low efficiency in query,this system applies multidimensional data model and the indexing technology to the Key-value database,storing fact data in forms of multidimensional data and indexing on the multidimensional model in order to speed up the query.The establishment of multidimensional data model and the implementation of indexing technology is systematically described.Finally the thesis briefly compares it to the mainstream Key-value database in terms of advantages and disadvantages.
