2. Description of the Related Art Conventionally, design and maintenance information utilized for maintenance and management work of large plants such as power plants is provided by books, various lists, memos, or operation / maintenance personnel managed in a book storage or bookcase. It is mainly handled by humans due to their experience and knowledge. Recently, as a technique for rationalizing such a situation, a book management system using an optical disk or the like is generally used.

However, the book management system takes measures such as finding information based on the book name and the like, and for example, a large number of facilities such as a power plant and complicated and diverse books are used. In the environment, it is difficult to find the information needed for each work efficiently and quickly, and it takes a lot of personnel and time, so it is applied only to some limited information. In many cases.

Some design and maintenance information is managed by using a computer or a database system. However, even in this case, it is the current situation that the data required by each department is individually made into a database, and it is necessary to share information among multiple departments in maintenance management work that requires a wide variety of information. Therefore, it is difficult to quickly and efficiently find information managed by other departments.
