A Platform for Utilizing Information across the Web and the Real World

We propose a way to wrap both Web information spaces and pervasive data environments by providing a uniform view of databases. Search result of search engines and processing results of several Web search services are wrapped and viewed as "virtual tables" of relational databases. The device manipulation environment and data captured by those devices are also viewed as "virtual tables ". Invoking a ubiquitous device is regarded as the insertion of a tuple into a virtual table. Since both the Web and pervasive device environments are regarded as uniform virtual tables, it becomes easy to develop services over the Web and the real world.
