A system and method for managing a database in a data distribution service is provided. Exemplary embodiments may disclose a system which manages a database in a data distribution service (DDS) in which a plurality of nodes connected to each other through a network are subscribed to the DDS for at least one topic, the system comprising: a first agent configured to be positioned at a first node, among a plurality of nodes, configured to receive a control request for the database from a user application operating in the first node, and transmit the control request to at least one node subscribed to a topic registered for the first node; a second agent configured to be positioned at a second node, which is different from the first node, receive the transmitted control request, control a database table according to the topic on a basis of the received control request, and transmit a result of controlling the database table to the first node.
Description
[0001] This application claims priority to Korean Patent Application No. 10-2013-0014973 filed with the Korean Intellectual Property Office on February 12, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Exemplary embodiments relate to a system and method for managing databases in a data distribution service. More particularly, the exemplary embodiments relate to a system and method for processing a request to control a database by an agent in a data distribution service in which a plurality of nodes connected to each other through a network target at least one of a plurality of topics or multiple topics to subscribe to the data distribution service respectively. Background technique [0003] In the prior art environment, a plurality of devices may be dynamically connected to each other to form a single network domain and exchange data with each other. In the prior art environment, it is more efficient to use an N:...
