Abstract

<P>PROBLEM TO BE SOLVED: To provide an electronic filing system preventing a lowering of processing speed of software and reducing traffic by reducing the amount of information transmitted to a network, to a required minimum in checking in a file and a folder. <P>SOLUTION: In a client/server type electronic filing system wherein the file 12 stored in a server 11 is shared with a client 13, the client 13 prepares a time and date file 14 when checking out the file 12 stored in the server 11, collates the file 12 at the check-in with the time and date file 14 to determine whether it is a check-in object, and checks in only the check-in object file 12. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an electronic filing system that checks out files and folders via a network, changes them, and checks them in.

  In recent years, with the development of the Internet, processing for exchanging files and folders via a network has increased. Also, from the viewpoint of configuration management and security, it is common to check out files and folders, change them, and check in.

  In other words, in a client / server type electronic filing system in which a plurality of clients share a file or folder stored on a server, when a client checks out through the network and makes a change, the change is made. Files and folders can be referenced by other clients.

At this time, in order to handle various information, a plurality of files and folders are often checked out / checked in at the same time. Therefore, the server can perform check-in / check-out management of documents shared by clients, and have a function of restricting check-out of the same file or folder by a plurality of clients, so that simultaneous double updates to the same document can be reliably prohibited. There is what has been made (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 11-85598

  However, when checking out, all files and folders are not always updated, but they are often checked in at once. In some cases, it is checked whether it has been updated or not. In such a case, it is common to obtain server file information via the network and compare it with the client file information. .

  In the software execution speed, processing that is most likely to become a bottleneck is processing via a network. However, since the load is applied here, the overall processing speed also decreases. Even if the number of files is large or the file size is large, the traffic increases because all files are streamed as they are. Also, when performing an update check, the network must be used in order to acquire server information, so traffic eventually increases. As a result, there may be a delay in transferring other information, or in the worst case, information may be lost.

  An object of the present invention is to provide an electronic filing system capable of minimizing the amount of information to be sent to a network when checking in a file or folder, preventing a reduction in software processing speed and reducing traffic.

  The electronic filing system according to the invention of claim 1 is a client / server type electronic filing system in which a plurality of clients share a file or folder stored in a server. The client is a file or folder stored in the server. A date / time file is created at the time of check-out, the file / folder at the time of check-in is compared with the date / time file to determine whether it is a check-in target, and only the file or folder to be checked-in is checked in And

  The electronic filing system according to a second aspect of the present invention is the electronic filing system according to the first aspect of the present invention, wherein when the client has a newer one than the time stamp of the date / time file in the checked-out file or folder, When the number of registered files and folders is different from the number of files and folders at the time of check-in, it is determined to be a check-in target.

  According to the present invention, since it is not necessary to perform an update check via the network in the check-in process, it is possible to reduce the bottleneck of software execution speed and network traffic.

  Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing the processing contents at the time of check-out of the electronic filing system according to the embodiment of the present invention. When the client 13 checks out the file 12 stored in the server 11, the client 13 receives a copy of the file 12 stored in the server 11 and stores it as a file 12 '(S1). A file 14 is created (S2). The date and time file 14 registers the date and time of checkout and the number of files and folders. That is, when paying out files and folders to the client 13, a date and time file 14 is created, and the number of checked out files and folders is registered therein.

  FIG. 2 is a block diagram showing processing contents at the time of check-in of the electronic filing system according to the embodiment of the present invention. When checking in the server 11 from the client 13, the client 13 collates the file or folder at the time of check-in with the date and time file 14, and determines whether or not it is a check-in target (S11). If it is a check-in target, the file 12 'is transmitted to the server 11 (S12), and the date / time file 14 is deleted (S13). As a result, only the file or folder to be checked in is checked in.

  It is determined whether or not it is a check-in target based on whether or not any of the following conditions is satisfied. If neither condition is satisfied, the file 12 ′ is not transmitted to the server 11.

(1) A file or folder that has been checked out is newer than the time stamp of the date / time file 14.

(2) When the number of files and folders registered in the date and time file 14 is different from the number of files and folders at the time of check-in.

  As described above, the determination as to whether or not the file 12 ′ has been updated can be completed within the client 13. As a result, since only necessary files can be flowed over the network, bottlenecks and traffic can be reduced. In the above description, the entire group of checked-out files is targeted. However, by improving the performance of individual files, further improvement in performance can be expected.

Claims (2)

  In a client / server type electronic filing system in which a plurality of clients share a file or folder stored in a server, the client creates a date / time file when checking out the file or folder stored in the server, and checks An electronic filing system characterized by collating a time file or folder with the date and time file to determine whether or not it is a check-in target and checking in only the check-in target file or folder. When the client has a check-out file or folder that is newer than the time stamp of the date and time file, or the number of files and folders registered in the date and time file and the number of files and folders at the time of check-in The electronic filing system according to claim 1, wherein the electronic filing system is determined to be a check-in target when they are different.
