DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an information sharing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

[Configuration of Apparatus] FIG. 1 is a block diagram showing a configuration example of a server system for realizing the information sharing apparatus of the present embodiment.

In FIG. 1, the user of the client 1 is:
If the user accesses the information sharing apparatus 3 via a network such as the Internet 2 and is authenticated as a user, the user can access the shared information provided by the information sharing apparatus 3.

Although the information sharing apparatus 3 shown in FIG. 1 is configured as a duplex system in consideration of reliability and high speed, it may be a single system or a triple system or more (multiplexing). In the case of a multiplexed system, the device or device to which information flows and is determined by the operating state of the device or device at that time, and the device or device that can receive and process the information The process is executed by. Therefore, in the following, for ease of explanation, a description will be given assuming that the system is configured by one system regardless of the configuration illustrated in FIG.

The request from the client 1 is received by the router 31 via the Internet 2 by the IP (Internet Protocol) address added to the packet, and is sent to the hub (HUB).
Via 32, it is sent to the Web server 33.

[0014] Web server receiving the request of client 1
33 causes the AP server 38, which executes an application (AP) for realizing authentication, information sharing, and the like in response to the request, to process the request via the hub 37. Web server 33
It is also possible to implement the application on the Web server 33 and execute the application on the Web server 33.

An application running on the AP server 38 requests information from a database (DB) server 35 as necessary. This request is sent to the DB server 35 via the hub 39. The DB server 35 extracts information from the database (DB) 37 in response to the received request, and returns the extraction result to the application.

In the above configuration, the Web server 33
e, authentication is realized by Open SSL, the AP server 38 is realized by Apache JServ, and the DB server 35 is realized by Oracle or the like. In addition, FDDI (Fiber Disp.) Is used between the DB server 35 and the storage device that stores the DB 37.
(Distributed Data Interface) 36 and other connections are connected by a network such as 100Base-TX. However, these configurations are not particularly limited.

In FIG. 1, four or more Web servers 33 are connected in parallel. This is because the load applied to the information sharing apparatus 3 when the number of users is large is increased by the Web server 33 that communicates with the client 1 and executes the application.
Considering that you concentrate on In other words, by operating four Web servers 33 in parallel, each Web server 33
The aim is to distribute the load to Of course, the number of Web servers 33 may be increased or decreased according to the number of users, and in the case of the present embodiment, the Web server 33 and the DB server 35 have a configuration separated from each other. It can be done very easily.

[Example of Application] As an example of an application, an outline of an operation in which the client 1 accesses the information sharing apparatus 3 to browse, add, update, or delete shared information will be described with reference to FIG.

The Web server 33 is a Web server for sharing information.
The page is published via the Internet 2. When the user of the client 1 accesses the web page in step S1, the web server 33 authenticates the user of the client 1 in step S2.

When the user is confirmed to be an authorized user by authentication, the Web server 33 requests the AP server 38 to create a list of information managed in association with the user of the client 1 in step S3. In step S4, the AP server 38 uses the DB server to create the requested list.
Instruct 35 to extract information. In step S5, DB server 35
Retrieves information associated with the user of the client 1 from the documents and additional information stored in the DB 37 and returns the result to the AP server 38.

In step S6, the AP server 38 creates a list described in HTML (Hyper Text Markup Language) based on the search result, and passes the created list to the Web server 33. If the information is managed hierarchically, the AP server 38 first creates a top-level list and
Then, a list corresponding to the information of the layer requested by the user is passed to the Web server 33. In addition, the list includes the following information based on the information returned from the DB server 35. (1) Icons and file names or headings of information available to users of Client 1 (2) If information is managed in multiple layers, icons and folder names or headings of folders on the path (3) Documents Or a memo or headline that is not managed as a folder and is information that can be browsed by the user of the client 1. icon

The Web server 33 that has received the list passes the list to the client 1 in step S7. Therefore, a list of the top layer or the layer requested by the user is displayed on the screen of the client 1. The user
In step S8, by clicking an icon or button on the displayed list, the listed information can be browsed, updated and deleted, and the information can be added.

In step S9, the Web server 33 transmits a user operation (request) to the AP server 38. Therefore, according to the operation (request) of the user, new information is added to the DB 37, the information stored in the DB 37 is supplied to the client 1, or updated or deleted by the AP server 38 and the DB server 35. When information is added or updated, the information is associated with the user.

If the DB 37 has been updated, the process proceeds to step S5
Then, a new list is passed to the client 1 by the subsequent processing. The processes in steps S5 to S9 are repeated until the connection between the client 1 and the Web server 33 is disconnected, such as when the client 1 logs off.

Although not described in detail, the access right to the shared information is set for each user, and viewing, adding, updating, or deleting the shared information is performed within the range of the access right.

In the above operation, the user operation is provided from the Web server 33 running on the client 1,
b. This is done through a screen displayed by the browser, and no special software is required to access the shared information.

As described above, according to the present embodiment, since the Web server is used as a contact point of the information sharing apparatus, the client side accesses the shared information using the Web browser provided for most platforms. Can be.

Further, since the management of the shared information, the application, the Web server, and the like are executed by independent devices, even if the number of users accessing the shared information increases, it can be dealt with simply by adding a Web server as a window. can do. That is, it is extremely easy to maintain the response of the system.

When the execution of an application becomes a bottleneck, the number of AP servers can be freely increased.
You just need to add more AP servers.
