Abstract
An embodiment of the invention provides a device for searching indexes for sensor tag data. The can include a memory that has sensor tag data stored as a time series; an interface that is configured to receive tag names and time segment information for searching sensor tag data; and a processor that is configured to determine partitions of the memory having the sensor tag data stored therein based on the time segment information and configured to determine corresponding indexes and leaf nodes for the determined partitions based on the tag names and the time segment information. An embodiment of the invention can provide an optimized index structure for and a method of storing and searching time series sensor tag data with which most query patterns relating to time series sensor tag data can be satisfied.
