Preliminary Study on Data Management Technologies of Internet of Things

Internet of Things (IOF) is the outcome of the combination of sensor technology and Internet development. It is an important part of future Internet. Due to the complexity and unpredictability of IOF, data management of IOF faces great challenges. This paper first briefly introduces the concept of IOF. Based on the characteristics of IOF such as mass scale, data polymorphism, rich semantic, and real-time query, it then emphatically analyzes data quality control technology, data fusion and integration technology, data query and optimization technology, complex event processing technology, data storage and compression technology of IOF.
