METHOD FOR APPLYING A SERVICE ORIENTED ARCHITECTURE BASED WEB SERVICE IN A LEGACY SYSTEM IN ORDER TO IMPROVE THE REUSABILITY OF THE FUNCTIONS OF AN EXISTING LEGACY SYSTEM

摘要

PURPOSE: A method for applying a service oriented architecture (SOA ) based web service in a legacy system is provided to maximize the reusability for a service by mutually sharing the service of the legacy system regardless of a platform.;CONSTITUTION: A web service providing unit (301) provides a SOA based web service corresponding to the legacy service of a legacy system, generates an identifier when the web service is requested, and includes information about communication with an identifier information storage (304), a legacy system management unit (302), and a connection unit (303). The legacy system management unit generates the legacy system connection unit according to the control of the web service providing unit. The legacy system connection unit transmits the request of the web service providing unit to the legacy system by using a legacy application programming interface (API).;COPYRIGHT KIPO 2013;[Reference numerals] (202) Web service providing realization unit; (204,BB,CC,DD) Web service; (206) Legacy APT; (301) Web service providing unit; (302) Legacy system management unit; (303) Legacy system connection unit; (304) Identifier information storage; (AA) Legacy systems; (EE,FF,GG) TCP, UDP, etc.; (HH) Legacy system connection unit generation; (II) Legacy system connection unit (#2); (JJ) Legacy system #1; (KK) Legacy system #2
