Description

  The present invention relates to the ease of use of a document management system built on a Web server, Web client, and database server.

Conventionally, in a Web application system, when an application is composed of a plurality of pages, means for managing session information, which is a device for grasping a series of http and https protocol accesses as continuous, is provided on the Web server. It is often provided. When a normal logout request is made from the client side, this session management information is deleted as unnecessary, but when there is no logout request from the client, the session information remains on the Web server. Usually, after a certain period of time, the session information is deleted, and when there is a request for the same session after that, there is often a mechanism that warns that the session has expired.
JP 2000-172481 A

  However, it often happens that the user interrupts the operation without performing a formal logout operation for some reason during the operation and there is no request from the client for a long time. In the document management system, when the user tries to continue the operation after the session is terminated, the user transmits a login request to the Web client again, and the operation stored in the user's memory is selected from the hierarchical folders of the plurality of cabinets. It is necessary to select the middle folder again and continue the operation.

  In such a document management apparatus, when time passes and many hierarchical folders are created and documents are accumulated, the user's folder selection operation becomes complicated, and the continuity of the operation is interrupted and is difficult to use. There was a problem.

  The present invention has been made in view of the above-described problems. Even when a session is terminated, the initial login screen is displayed with the folder that was being operated open, and the user's operation can be performed. It is an object of the present invention to provide a document management method, apparatus, and program constructed on a Web system that can ensure continuity.

  Solve the above problems.

  By storing the last access folder information, it is possible to display the folder that was being operated in a selected state at the next login, and to ensure the continuity of the user operation.

Example 1
FIG. 1 is a block diagram showing the configuration of the document management system of the present invention.

  In FIG. 1, a plurality of clients 3 can access the server 1 of the document management system via the Internet 7 using http and https communication, or other communication methods between the Internet. The server 1 stores and manages folder information and documents for document management, and the client 3 manages the folder information and document information stored and managed in this way. The server 1 includes a web server 13 for performing communication between the Internet 7, a folder, a document management server 10 for managing documents, a folder, a folder for storing document management information, a document management database 11, and a file for storing document data. System 12, means 14 for creating and saving session information, which is a mechanism for grasping a series of http and https protocol accesses as continuous, means 15 for saving folder identification information accessed by the user, and monitoring session information If there is no response for a certain period of time, each is connected to a session deletion monitor 16 that deletes the session.

  Next, the document management apparatus in the system operating environment configured as described above will be described with reference to the flowcharts of FIGS. 2 and 3 and FIGS. 4, 5, 6, and 7. FIG.

  First, referring to FIG. 2, a flow for processing a request from a client on the Web server 13 will be described.

In FIG. 2, in step 201, a login request from the client to the document management apparatus is received. Next, in step 202, session information is created in the session information table, and the current date / time is stored as the “last access date / time”. (FIG. 4 is an example of a session information table)
Next, in step 203, it is checked whether or not “last access folder information” is stored with the user ID requested to log in in step 201. (FIG. 5 is an example of the final access folder information table)
If “last access folder information” is stored, the process proceeds to step 204 to acquire “last access folder” information from the document management server 10. Next, the process proceeds to step 205, where the final access folder information display HTML is created and transmitted to the client. (FIG. 7 is a display example of the initial screen on the client (when the previous session has expired))
If the “last access folder information” is not stored, the process proceeds to step 206, where the cabinet list display HTML is created and transmitted to the client. (FIG. 6 is a display example of the initial screen on the client (when the previous normal logout operation was performed))
Next, in step 207, a new request from the client is received.

  Next, the process proceeds to step 208 to check whether or not the session ID of the new request is in the session information table (FIG. 4). If the session ID is not stored in the table, the process proceeds to step 209, HTML for notifying the session expiration is created and transmitted to the client, and the process is terminated.

If the session ID is stored in the table, the process proceeds to step 209, and the last access date / time of the corresponding ID in the session information table is updated to the current date / time. (Fig. 4)
If the request from the client is “display selected folder information”, the process moves to step 212 to acquire information on the requested folder from the document management server 10. Next, the process proceeds to step 213, where the corresponding access folder information display HTML is created and transmitted to the client. Next, the process proceeds to step 214, and it is checked whether or not the corresponding user ID exists in the final access folder information table (FIG. 5). If the corresponding user ID exists, the process proceeds to step 215, and the last access folder information of the corresponding user ID in the final access folder information table (FIG. 5) is updated. If the user ID does not exist, the process moves to step 216, and the user ID and the last access folder information are added to the last access folder information table (FIG. 5). Next, the process proceeds to step 207 to receive a new request from the client.

  If the request from the client is “logout”, the process moves to step 217, and the session ID and the last access date / time of the corresponding session are deleted from the session information table (FIG. 4). Next, the process proceeds to step 217, where the user ID and the last access folder information are deleted from the last access folder information table (FIG. 5), and the process is terminated.

  If the request from the client is “other”, the process moves to step 219, and HTML corresponding to each request is created and transmitted to the client. Next, the process proceeds to step 207 to receive a new request from the client.

  Next, the processing flow of the session information deletion monitor on the Web server will be described with reference to FIG.

  In FIG. 3, in step 301, the current date and time are acquired from the system.

  Next, in step 302, the number of session information stored in the session information table (FIG. 4) is acquired.

  Next, the process proceeds to step 303, and the last access date and time stored in the session information table (FIG. 4) is acquired.

  Next, the process proceeds to step 304 where the current date and time and the last access date acquired in step 303 are compared to check whether or not a certain time has elapsed. If the predetermined time has elapsed, the process proceeds to step 305, and the session ID and the last access date / time of the corresponding session are deleted from the session information table (FIG. 4).

  Next, the process moves to step 306 to check whether or not an unchecked session ID exists. If it exists, the process returns to step 303. If it does not exist, the process ends.

  Next, table examples and display examples of the document management apparatus realized by the flowcharts as described above will be described with reference to FIGS. 4, 5, 6, and 7.

  FIG. 4 is an example of a session information table. The session ID and the last access date and time from the client using the ID are stored. Here, it is assumed that Session 3 has been deleted by the session information deletion monitor 16 because the session has expired. In the state of this table, when the session ID is specified as Session 3 and there is a request from the client, in step 209 of FIG. 2, HTML for notifying session disconnection is created and transmitted to the client.

  FIG. 5 shows an example of the final access folder information table. At present, the user ID “XXX” and the “¥¥ XXX.aaa ¥ operation check” folder as the final access folder are the user ID “XXX”. As a final access folder, a folder “¥¥ YYY.aaa ¥ Report ¥ 2001” is stored.

  FIG. 6 shows an initial screen on the client when a normal logout operation is performed last time with a user ID for which a login request has been made, or when a user ID that has not been used before is used when issuing a login request to the document management apparatus. Is a display example. For example, when login is requested with the user ID “ΔΔΔ”, the user ID and the final access folder information of the user ID “ΔΔΔ” are not stored in the final access folder information table of FIG. In step 206 of 2, a cabinet list display HTML is created and transmitted to the client.

  FIG. 7 is a display example of the initial screen when logging in with the user ID that caused the previous session expiration. For example, when login is requested with the user ID “XXX” that caused the previous session to expire, in the final access folder information table of FIG. 5, the user ID of the user ID “XXX” and the final access folder information “ Since “¥¥ XXX.aaa ¥ operation confirmation” is stored, the information of the last access folder information “¥¥ XXX.aaa ¥ operation confirmation” is acquired from the document management server in step 204 in FIG. “¥ XXX.aaa ¥ Operation Check” Folder information display HTML is created and sent to the client. For this reason, even if the user “XXX” does not remember which folder was in the middle of the previous operation, if this device is used, the folder during the next login operation will be displayed as the initial screen. The operation can be continuously executed.

  The present invention sets the means for storing the last access folder information and the means for transmitting the folder as the initial information screen by the above steps, so that the folder that was being operated in the document management system constructed on the Web system Is displayed in a selected state at the next login, and a document management method that can ensure continuity of user operations is provided.

  As described above, by storing the last access folder information, it is possible to display the folder that was being operated in a selected state at the next login and to ensure the continuity of the user operation. .
