抄録

The database is often used in the development of the system. For example, it is used to record the user info about the book at the library. The database is very useful. But it is difficult to get enough effect only by recording the data simply. When the target data is searched on the whole database, search time gets longer with the increasing recorded data. In the result, the speed of processing will decline. In this study, we tested a database about deleting method, fragmentation and index to make response of database speedy.
