摘　　要：大数据技术是继物联网、云计算技术之后IT业界又一次技术浪潮。为了全面深入地理解大数据技术的内涵,从大数据的定义及4V特征、关键技术及主要应用领域等四个方面进行阐述。介绍了大数据的基本概念、特征,总结了大数据的热门应用领域并用典型案例进行佐证,重点剖析了云计算、Hadoop、数据备份等三大核心技术及关键策略,最后对大数据应用中滋生的信息安全隐患提出了相应的对策。Big data is a new technical wave after the network of things and cloud computing. To understand big data technology, the definition and 4V characteristics, the key technologies and main application fields are systematically analyzed in the paper. Through the introduction of the basic conception, characteristics, the main application fields with typical cases are summarized. The core technologies, key strategies of cloud computing, hadoop and data backup are analyzed. The potential information safety risks are pointed out. The countermeasures are given to provide some suggestions and references for wider application and study in the future.
