Electronic Tickets on Contactless Smartcard Database

More recently, embedded databases and smartcard databases have emerged. To make such small databases practically useful, only a scale-down approach to a general-purpose relational database will be insuficient;some specializations for each application domain are also required. In this paper, we design a small database based on the experience of our electronic ticket project. The design includes a new data model that well represents a variety of small volume tickets, a role-based access control applied to each ticket, and a logging and rollback operations externalized in a way interacting with a preprocessor. We present that database functionality on a smartcard are helpful to build multi-party ticket applications.
