| Abstract(in English) | Storage devices used by handheld terminal that treats a geographic database as typified by a car navigation system is changing from DVD-ROM to HDD. HDD is updatable and faster than DVD-ROM, suit for the handheld terminal. But the current handheld terminal can't update the geographic database using only differential data because the handheld terminal treats the geographic database as a large file. Even if applying a DBMS to the handheld terminal and change it updatable, there is remains a fragmentation problem of a database incidental to long operation. To solve this problem, we propose a duplicate ID nearly located table having a tolerance to fragment and also present an estimate evaluation of our approach. |
