Abstract
Recently in the railway field and the industry field, it becomes more necessary to use data effectively in order to store and succeed to fields' know-how by information technology and in order to plan for further increase in business efficiency. However, there is a large amount of various data from plural different railway business systems, so it is difficult to utilize these data transversely. In order to solve the above problems, we propose a data utilization platform, especially including platform architecture, data relation generating/visualizing functions with data relation network model, and analysis components that can be reused in plural applications, for the railway field as the first instance.
