Abstract

Ubiquitous database places data everywhere. We focus on contactless smartcards combined with a small processor and memory for data storage. Very small DBMS implemented on them can interact through queries on a wireless communication. Ubiquitous database attaches such DBMSs to real world “objects” physically, and then allows different organizations to share information retrieved directly from physical goods, materials, or persons. We combined the theory with practice in the ticket digitalization project. Through the experience of our project, this paper will discuss how to manage ubiquitous database in the context of mobile commerce applications.
