Abstract
In business systems, lump-sum updates of the mass data are cxecuted by batch proccssing. Somc kinds of these batch processing could not be executed concurrently with online entry, so they had to be executed while the online entry are stopped such as in the night and holiday. As a result, various kinds of problems about the time management occurred. For example, since the data conversion work of the business change has to execute lump-sum update of the mass data on the designated date, it had to interrupt the online entry. Therefore, this work had to complete in the limited time. So, about the time management, various kinds of activities of attendant works such as the extra time of the real work, the preliminary confirmation of the work procedure and the rehearsal occurred. In this paper, we propose the preceding update method to do the batch processing, which executes the lump-sum update of the mass data, concurrently with the online entry. Moreover, we evaluate the case of applying it to a system change and a lump-sum update of an actual business system, which could not be concurrently executed with the online entry so far. And, we show the following : the schedule compression and flexible schedule development become possible in the work has to wait the completion of the online entry ; the time management becomes easier in the work of the business change because a time limit is eased.
