File management system

Abstract

Since both a physical storage place and a logical storage place in a storage system are separately managed as a directory structure, or a hierarchical structure, even in such a case that the physical storage place has been changed, the logical storage place which is displayed to the user is not changed, and thus, the user can use the file while the user need not become aware of the change of the file. When the contents of a file is displayed, a physical storage destination of the file is acquired based upon both a reference path and a relative path of the file, and then, the file is acquired from the physical storage destination.

Description

INCORPORATION BY REFERENCE [0001] The present application claims priority from Japanese application JP2005-168982 filed on Jun. 9, 2005, the content of which is hereby incorporated by reference into this application. BACKGROUND OF THE INVENTION [0002] The present invention is related to a file managing system and a file managing method, in which file substances are managed outside a database. [0003] As to documents having reusable characteristics which are known as medical application documents and commercial-purpose presentation documents, effective utilizations of knowledge and information which have been stored in organizations may constitute important factors in order to improve business efficiencies. To this end, such information related to files must be managed in connection with these files in order that not only these files are merely and commonly used, but also these files may be readily retrieved by users who intend to utilize these files. As means capable of managing file...

AI Technical Summary

Benefits of technology

[0006] Generally speaking, cost of storage apparatus operable in higher accessing speeds is increased, whereas cost of storage apparatus operable in lower accessing speeds is decreased. As a consequence, in such managing systems that files are stored outside databases and information as to storage destinations of these files is managed inside the databases, in the case that storage capacities of storage apparatus are decreased in connection with increases of data amounts, files whose accessing frequencies are high can be stored in storage apparatus operable in high accessing speeds, and files whose accessing frequencies are low can be stored in storage apparatus operable in low accessing speeds.

[0009] To achieve the above-described object, both a means for automatically determining a storage destination of a file since a system manager has previously set an allocation condition of the storage destination of the file, and also, another means for automatically changing a storage destination of a file since the system manager has previously set a condition for changing the storage destination of the file are provided. Also, a logical storage destination of a file to which a user accesses, and a physical storage destination of a file substance are separately managed. This file managing method may give such an effect that when the physical storage destination of the file is changed, the user need not become aware of the storage destination of the file.

Problems solved by technology

Generally speaking, cost of storage apparatus operable in higher accessing speeds is increased, whereas cost of storage apparatus operable in lower accessing speeds is decreased.

When system managers perform the above-described selective file storing operations, very cumbersome works are necessarily required, and furthermore, since storage destinations of files are changed, users must become aware of such a fact that the storage destinations of these files have been changed.
