no. 1 Embodiment approach

[0031] figure 1 A configuration example of the data processing device 10 according to the first embodiment is schematically shown. Such as figure 1 As shown, the data processing device 10 has a data management function unit 11 , a data storage unit 12 and a data recording unit 13 . The data management function unit 11 communicates with the outside of the data processing device 10 and exchanges data with the data storage unit 12 and the data recording unit 13 constituting a database. Part or all of the functions of the data processing device 10 can be realized by causing a processor (such as a CPU (Central Processing Unit)) to execute a computer program stored in a memory.

[0032] The data generation source is connected to the data processing device 10 . The number of data generation sources connected to the data processing device 10 can be changed dynamically. That is, a data source connected to the data processing device 10 may be added or deleted. Examples of data gene...

Abstract

A data processing device according to a first embodiment of the present invention comprises: a first storage unit capable of storing data permanently; a second storage unit having a faster reading speed than the first storage unit; a processing unit for storing, in the first storage unit, data generated by a data generation source, and further storing, in the second storage unit, data generated bythe data generation source, if data generated by the data generation source matches pre-registered search conditions; and a search unit for searching the second storage unit as a matter of higher priority than the first storage unit, in response to a data processing request from an application.

Description

technical field [0001] The present invention relates to a technique for rapidly storing huge amounts of data in a database and referring to the data in the database. Background technique [0002] In recent years, attention has been drawn to IoT (Internet of Things), which connects various devices / sensors to the network and utilizes data collected from these devices / sensors. In IoT, data is collected from multiple devices / sensors, so a data processing device with a database capable of storing large amounts of lightweight data is required. [0003] In various cases where IoT is utilized, the latest data acquired from devices / sensors is used for analysis, prediction, and actuation. In this regard, the following 2 points become characteristics of the database. [0004] 1. Write data frequently in time series order. [0005] 2. The frequency of referring to the value belonging to the latest division in time series among all the data is high. [0006] Furthermore, as a typical...
