Abstract

PURPOSE:To eliminate a bottle neck in transmission and to prevent a transmission waiting time due to the transmission of retrieval result information from being generated by providing a retrieval result transmission procedure being operated independently in each task at every user terminal. CONSTITUTION:In a reservation retrieval execution procedure 1, a data base file 4 is retrieved by executing all of the retrieval conditions reserved and registered by plural users targeted for a data base sequentially at a reserved time interval, and in a transmission information allocation procedure 2 being operated by another task, the retrieval result information is allocated one by one to each of N user terminals 5-1-5-N as transmission information. Therefore, out of N retrieval result transmission procedures 3-1-3-N, each of X(0<=X<=N) retrieval result transmission procedures corresponding to each of X user terminals in which the transmission information exist is operated by respective independent task, and each allocated transmission information is transmitted to each of the user terminals in an on-line operation. In such a way, it is possible to eliminate the transmission waiting time due to the transmission of the retrieval result information to another user.

している。Conventional database reservation search systems sequentially execute search condition expressions that have been reserved and registered in advance by multiple users on a computer system that has a database, and use the obtained search result information to reserve search condition expressions. It is sent online sequentially to each user terminal that is the registration source.

題点がある。The conventional database scheduled search system described above repeatedly executes the search condition expressions and transmits the search result information obtained from the search condition expressions in series for all the search condition expressions that have been reserved and registered. The problem is that the long online transmission time creates a transmission bottleneck, and search result information cannot always be transmitted at the time reserved for each user.

) A transmission information allocation procedure for allocating the search result information successively provided in the scheduled search execution procedure as transmission information one after another for each of the N user terminals connected online; (C) the scheduled search execution procedure; and the transmission information assignment can operate in parallel with the procedure, and the transmission information assignment is a search result transmission procedure of N pieces in which each of the transmission information assigned in the procedure is transmitted in parallel to each of the corresponding user terminals. ,
It is configured with.
