摘要

PROBLEM TO BE SOLVED: To provide a real-time data acquisition IF system which provides a unified interface for easily acquiring real-time data for a client who utilizes the real-time data.;SOLUTION: A real-time data acquisition interface system includes: a subscription data registration unit 31 which receives a registration from a user for data to be a subscription target and holds the registration as a subscription status 37; a data acquisition unit 32 which specifies data and a server 10 on the basis of the subscription status 37, acquires the data, and accumulates the data as acquisition data 38; and a data transfer unit 35 which transmits data accumulated in the acquisition data 38 while specifying a client 40 on the basis of the subscription status 37. The data acquisition unit 32 further includes a PULL-type acquisition section 33 and a PUSH-type acquisition section 34. When starting acquiring data, history data until the start are acquired from the server 10 by the PULL-type acquisition section 33 and transmission of additional data from each server 10 is awaited by the PUSH-type acquisition section 34 thereafter.;COPYRIGHT: (C)2012,JPO&INPIT
