Abstract
We renewed the transportation planning and the operation control systems for
the high-speed railways of the East Japan Railway (JRE) using a relational
database management architecture in 2008. The JRE has five bullet train lines
(SHINKANSEN). It has an information system named COSMOS to control and
operate SHINKANSEN properly. The transportation planning sub-system has six
function groups which are developed by different manufacturing companies. We
decided to adopt an integrated relational database model and database interfaces
in order to restrain consistency failure of database transactions. We chose NS
solutions (NSSOL) as the manufacturing company for database modeling and
interface development, since NSSOL has deep knowledge and experiences to
construct a database model for railways. We and NSSOL designed and
developed the database that has about 1400 tables which contain several hundred
gigabytes of data. Since we developed the database on our own, we are able to
understand the whole structure of the database CRUD (Create, Read, Update or
Delete data on database) and to fix failures in the architecture.
Keywords: train traffic scheduling, real-time rescheduling, relational database.
