DATABASE DEVICE

摘要

A KVS data processing unit, upon receiving a KVS type command of a database system in which index data and actual data are stored in a pair, manipulates data stored in a storage device based on said command. An SQL command execution unit, upon receiving an SQL command, serializes this command, generates KVS type data, and passes this data to the KVS data processing unit. A KVS command processing unit, upon receiving a KVS command, serializes this command, and transmits this data to the KVS data processing unit.

主权项

1. A database device, comprising:
a storage device that stores data by a database system in which index data and actual data are stored in a pair; a data processing device that upon receiving a first command described in a first database language which is a database language for the database system in which index data and actual data are stored in a pair, manipulates data stored in the storage device based on said first command; a second command execution device that upon receiving a second command described in a second database language which is a database language different from the first database language, serializes this second command, generates data configured from index data and actual data, and passes this data to the data processing device; a first command processing device that upon receiving the first command described in the first database language, serializes the first command, generates data configured from index data and actual data, and transmits this data to the data processing device; and an interface device that upon receiving the first command described in the first database language from an application, passes this first command to the first command processing device, and upon receiving the second command described in the second database language, transmits said second command to the second command execution device.
