Description

[0001]
TECHNICAL FIELD OF THE INVENTION
According to the present invention, in a client-server system, screen data including a request is transmitted from a client to a server using a function of a web browser, and screen data including a message or a processing result is transmitted from a server to a client. The present invention relates to a data area management method for a system (hereinafter, referred to as a “web browser using processing system”) in which data processing is performed by exchanging screen data.
[0002]
In particular, the present invention, in the above-described web browser use processing system, when the web browser launches a plurality of windows and frames, and performs input and the like in a plurality of windows and frames and transmits them to the server in parallel, The present invention relates to a data area management method in a web browser use processing system that enables a server to display a correct processing result in each window or frame.
[0003]
Also, in a normal web browser processing system, a certain screen transition method is defined on the server side so that processing can proceed according to a certain processing procedure, and the user can freely display screens other than the applicable processing procedure However, the present invention not only allows the data processing by the screen transition to be performed correctly, but also allows the user to use the functions such as “create new” and “return” of the web browser. The present invention relates to a data area management method in a web browser utilization processing system that enables operations such as opening a simple screen.
[0004]
[Prior art]
Conventionally, business processing ("business processing" refers to processing of a large number of data in a certain procedure as typified by business processing in a company, etc. However, in this specification, "business processing" refers to the target Large-scale data processing, such as business, is not limited to business of a company or the like.) Has been performed by a system including a host computer and a terminal.
[0005]
Recently, client-server systems have been widely adopted in place of host computers. In a client-server system that targets data processing such as business processing, the client acts as a terminal and sends a request to the server, and the server receives the request from the client and performs data processing to perform the processing. The result is returned to the client.
[0006]
In a client server system, a web browser and a web screen are widely used as tools for exchanging such requests and processing results. This is because a web browser is a convenient tool for browsing the screens on a server, and is a universal software for a personal computer (PC) constituting a client worldwide.
[0007]
In a client-server system for data processing using a web browser (a web browser-based processing system), the server uses a method of screen transition (screen transition) according to a business processing procedure (screen transition) so as to match the procedure. ) Are defined. Requests and input data from the user, and messages and processing results from the server are performed through exchange of these screen data.
[0008]
When a user wants to perform a predetermined business process, start a web browser on the client, access the server, display the first screen of a series of business process screens, and then enter data according to the instructions on the screen Or select a request from a given selectable request button and have the server execute it. The server performs predetermined data processing using the request or input data input by the user, incorporates the processing result into a screen, transmits the processing result to the client, and displays the result on a web browser. Through such exchange of information, a series of data processing of business processing can be advanced.
[0009]
By the way, in a processing system using a web browser, at the stage of a certain process, only one next process is determined (even if the process branches, one next process is determined after the branch), so that the user can display the same screen. When copying and branching to a plurality of processes or returning to the previous screen on the web browser, the system performs unintended processes such as performing duplicate processes. Conventionally, such an unintended screen transition is regulated by a system (server) or avoided by an instruction to a user.
[0010]

[0011]
[Problems to be solved by the invention]
However, it is sometimes convenient if a plurality of screens can be opened in the same web browser and the same business process can be processed in a plurality of windows simultaneously and in parallel. For example, when booking three flights on an airline ticket reservation site, it is convenient if reservations can be made simultaneously in three windows.
[0012]
Web browsers are designed and developed so that users can freely browse contents (screens) at any time, and there is a demand to use this function. For example, displaying a past screen by pressing the "Return" button or opening a new window by pressing the "New" button are very useful functions for the user, so there are cases where you want to use this. .
[0013]
On the other hand, if the above operation is performed by a conventional processing system using a web browser, an error may occur such that a processing result for a request from one window is displayed in another window. This will be described with reference to FIG.
[0014]
According to a typical web browser, when the web browser first accesses the server, a session area corresponding to the web browser is created.
[0015]
The session area is a so-called work area of a web browser, and specifies a web browser and associates the web browser with the web browser. When a plurality of web browsers access the server, each web browser secures a specific session area. Each session area has one data storage area (data store) storing data used for data processing.
[0016]
If a web browser that is already open opens a new window and sends a request from each window to the server, all windows belong to the same web browser, so the same session area is shared on the server. Become. Also, the same data store will be used.
[0017]
Therefore, if requests are simultaneously transmitted from the opened windows, data held in the data store of the session area on the server may be displayed in a window different from an expected window. From the user's point of view, the processing result of the window will be incorrect.
[0018]
Further, even when the window is a frame configuration screen, an application may be executed in a plurality of frames, and requests may be transmitted from each application simultaneously and in parallel. In this case, data of the data store in the same session area may be displayed in a frame different from an expected frame. In such a case, data inconsistency or data error occurs.
[0019]
Therefore, the problem to be solved by the present invention is that in a web browser utilization processing system, a case where a plurality of windows are started up by a web browser and processing is performed simultaneously and in parallel, or when a window is a frame configuration screen and the same window It is an object of the present invention to provide a data area management method in which the result of data processing is correctly displayed when processing is performed simultaneously and in parallel on a plurality of frames.
[0020]
[Means for Solving the Problems]
The data area management method according to the present invention includes:
In a server that receives a request from a client via a web browser, performs a process, and then transmits a processing result to the client web browser, the server process first accesses the server after the client web browser is started. Sometimes generating a session area corresponding to the web browser, generating a window ID corresponding to the window when the web browser newly opens the window, and storing data to be displayed in each window. And generating a corresponding data store and associating it with each window ID.
[0021]
When the window is a frame configuration screen, the server process includes generating an application ID for each frame as a lower unit of each window ID, and storing data to be displayed by application software in each frame. Generating a data store and associating the data store with each application ID.
[0022]
According to the present invention, since the minimum expression unit of an HTML page and the management unit of the data store are made to match, even when a plurality of windows or frames are started by a web browser and a plurality of application softwares are simultaneously processed, The data store corresponding to each window or frame can be allocated, and no data error occurs.
[0023]
A back-end server that performs processing in response to a request from the server; and when the server generates the window ID or the frame ID, the server communicates with a back-end server that performs processing related to the window ID or the frame ID. You can set and register connection information.
[0024]
According to the present invention, the processing result of the back-end server is displayed in the correct window or frame via the connection information and the window ID or the frame ID, and no data error occurs.
[0025]
The server deletes or releases the corresponding window ID or application ID and the corresponding data store when receiving an instruction to delete the data area from the application software, or sets when receiving a request from a web browser. The window ID or application ID whose retention time has passed and the corresponding data store are deleted or released, or all window IDs or application IDs of sessions whose session expiration time has passed when the set session expiration time has been reached are reached. The data stores corresponding to them can be erased or opened.
[0026]
When the server deletes or releases the window ID or the application ID and the data store corresponding to the window ID or the application ID, the server can perform processing for terminating the connection information with the backend server.
[0027]
According to the present invention, a specific data area is deleted when instructed by application software, and when a request is received from a web browser, a window ID or the like that has exceeded the set retention time at that time is deleted, and the session is enabled. When the time has expired, all the window IDs and the like of the sessions that have passed the session effective time can be deleted.
[0028]
A data area management method according to the present invention is a server that receives a request from a client via a web browser, performs processing, and transmits a processing result to a client web browser, wherein the server transmits a window ID from the web browser. Upon receiving the request to assign, the new window ID is numbered, the window ID is sent to the web browser, and the web browser assigns the window ID to the newly opened window, or the web browser sends the processing result to the web browser. The transmission is performed to the window with the assigned window ID.
[0029]
According to the present invention, it is possible to assign a window ID on the server side and synchronize with the web browser, or to proceed with the process using the window ID assigned on the web browser side.
[0030]
A data area management method according to the present invention is a server that receives a request from a client via a web browser, performs processing, and transmits a processing result to the client web browser. It has a plurality of screens in which transitions are defined, each screen has a copy mode setting value, and when a new window is created by operating a web browser, a new window ID is set according to the copy mode setting value. All the data stores generated and associated with the window ID of the copy source screen are duplicated and associated with the new window ID, or a new window ID is generated and associated with the window ID of the copy source screen. After duplicating only the datastore definition, Get the screen display data by entering a click, or, it is characterized in that to perform the process of the forced erase the web browser.
[0031]
According to the present invention, when a new window is created by the operation of the web browser, the copy mode setting value is used to copy a screen having a new window ID, or to force a transition to a predetermined screen, or In addition, the process of creating a new window can be restricted.
[0032]
When the server receives the URL input by the user, the server can generate a new session area having the window ID of the screen before receiving the URL.
[0033]
According to the present invention, in a business processing system in which screen transitions are defined, a user can freely input a URL and return to the original business processing by the window ID of the screen before receiving the URL. it can.
[0034]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the “method of managing data area in a web browser using processing system” according to the present invention will be described below.
[0035]
FIG. 1 illustrates a data area management method in a web browser use processing system according to an embodiment of the present invention.
[0036]
In the example of FIG. 1, the web browser use processing system 1 has a server 2 and a client 3, and usually there are a plurality of clients 3, in which a plurality of web browsers 4, 5,. Has been raised. The example of FIG. 1 shows a state in which the web browser 4 accesses the server 2 and a session area 6 corresponding to the web browser 4 is generated in the server 2. When another web browser accesses the server 2, another session area (not shown) is generated and associated.
[0037]
Assuming that the web browser 4 opens the windows 7, 8, and 9, window IDs are generated corresponding to the respective windows. In the example of FIG. 1, the window 7 is associated with the window ID 10, and the window 9 is associated with the window ID 11.
[0038]
In the example of FIG. 1, the window 9 is a frame configuration screen, and has a frame (1) and a frame (2). Frame (1) and frame (2) each execute application software separately. In such a case, in this embodiment, as shown in FIG. 1, an application ID 13 corresponding to the frame (1) and an application ID 12 corresponding to the frame (2) are generated below the window ID 11. .
[0039]
A data store for storing data used for each window ID or application ID is generated.
[0040]
That is, the data store 14 is directly associated with the window ID 10 that is not the frame configuration screen, the data store 15 is associated with the application ID 12, and the data store 16 is associated with the application ID 13 with the window ID 11 that is the frame configuration screen. Attached.
[0041]
As described above, in the present invention, the unit of data area management is generated in the order of window unit, frame page unit, and data store unit from the top, and the minimum expression unit of the HTML page (frame unit in the case of the frame configuration screen) The management unit of the data store is matched, and the window unit of the web browser is defined as the window ID and the application ID of the frame page.
[0042]
As a result, the result of the processing by the server 2 is stored in the data store associated with the minimum expression unit of the HTML page, and when the screen is displayed on the web browsers 4 and 5, the data store of the data store corresponding to the individual page is displayed. Assignment becomes possible, and no data error occurs.
[0043]
FIG. 2 shows a modified example of the web browser use processing system 1, that is, a web browser use processing system further including a back-end server in the configuration of the web browser use processing system 1. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals as those in FIG. 1, and duplicate descriptions are omitted.
[0044]
Here, the back-end server is a server that performs individual processing in response to a request from the server 2 (also referred to as a “front-end server” for the back-end server). Normally, it is preferable that the back-end server be a server that can perform routine processing at high speed.
[0045]
In this embodiment, when the window ID and the application ID are generated, the creation information of the data management area is passed to a back-end connector (not shown). The back-end connector generates connection information with the back-end server. The server 2 sets and registers connection information with the back-end server. The connection information is information that links a processing job in the back-end server with a window ID and an application ID.
[0046]
As shown in FIG. 2, assuming that the processing of the window ID 10 is performed by the back-end server 21, the connection information 23 is set and registered, and a processing request for the window ID 10 is requested to the back-end server 21 as shown in FIG. The processing result of 21 is returned to the window ID 10.
[0047]
In the case of the frame configuration screen, as shown in FIG. 2, assuming that the processing of the application ID 13 is performed by the back-end server 22, the connection information 24 is set and registered, and the processing request for the application ID 13 is sent to the back-end server 22. Then, the processing result of the back-end server 22 is returned to the application ID 13.
[0048]
According to the correspondence between the connection information 23, 24 and the window ID or the application ID, when the screen is displayed on the web browsers 4, 5, the data store corresponding to each page allocates the result of the processing by the back-end servers 21, 22. Data errors.
[0049]
However, as described in the embodiment of FIG. 1 and FIG. 2, if data area management is performed for each data store associated with the minimum expression unit of an HTML page, the problem of session overload can be solved. May be required.
[0050]
Normally, the session area is retained until there is no access from the web browser for a certain period. Even if the user closes the web browser halfway, the server side cannot automatically detect that the web browser has been closed, so the session area is stored until the above-mentioned fixed period elapses.
[0051]
In particular, when a plurality of processes are performed simultaneously and concurrently by one web browser as in the present invention, the session area becomes large, and if any one of the windows of the web browser accesses the server, the use of the session area is increased. The data area is held up to the window that has not been set. Therefore, there is a possibility that the invalid data area increases and the performance of the server deteriorates.
[0052]
The present invention also includes a method for solving the problem of overloading the session. However, the release of the data area is not essential for the generation of the window ID or the application ID according to the present invention depending on the capability of the system.
[0053]
According to the present invention, the data area is released by three methods.
[0054]
FIG. 3 illustrates a method for releasing a data area according to the present invention.
[0055]
As shown in FIG. 3A, a first method of releasing a data area according to the present invention is as follows: when an instruction to delete a data area is received from application software, a corresponding window ID and a corresponding data store, or , Window IDs and lower application IDs and their corresponding data stores are deleted or released. In the example of FIG. 3A, a specific window ID (3) is deleted by an instruction from the application software.
[0056]
As shown in FIG. 3B, the second method of releasing the data area according to the present invention is as follows: when an access is made from a web browser, window IDs that have exceeded a set retention time and a corresponding data store, or , Window IDs and lower application IDs and their corresponding data stores are deleted or released. In the example of FIG. 3B, when an access is made from the web browser, the elapsed time of each window ID is checked, and the window IDs ([1], [2]) that have passed the set holding time at that time are checked. Delete. The second method is effective when the application software cannot instruct the release of the data area as in the first method.
[0057]
The third method of releasing the data area according to the present invention is, as shown in FIG. 3C, when the set session valid time is reached, all window IDs of the sessions that have passed the session valid time and correspond to them. The data store or the window ID and its lower application IDs and the corresponding data store are deleted or released. In the third method, the data area is arranged on the server side without depending on the operation of the web browser, as in the first and second methods.
[0058]
The method for releasing the data area according to the present invention is preferably a combination of the above first to third methods, but is not limited to using in combination.
[0059]
In a web browser use processing system having a back-end server as shown in FIG. 2, when a window ID or the like is released, connection information associated with the window ID is also released and deleted.
[0060]
Next, an application example of the present invention to a business processing system in which a screen transition method is defined will be described.
[0061]
4, the web browser use processing system 25 has a web browser 26 and a server 27.
[0062]
The server 27 has a plurality of screens whose screen transitions are defined according to the definition of the business processing logic. Each screen has a copy mode setting value. It should be noted that “business processing logic” refers to a procedure that defines a processing procedure to be performed by a computer system for a data processing business in a company or the like.
[0063]
Here, the copy mode setting value of the screen means which screen of the business processing logic is connected when the web browser 26 creates a new window (when the screen is copied), or restricts copying. It is a value that specifies whether or not to do so.
[0064]
The copy mode setting value is defined as a specification for each screen.
[0065]
In this embodiment, there are the following three copy mode setting values.
[0066]
Copy mode 1: Copy the current screen as it is. The current screen is attached to a screen that may be displayed in a newly opened window. In this case, a new window ID is numbered, and the data store (definition and content) associated with the window ID of the copy source screen is copied and associated with the new window ID. In this case, the business processing logic is not executed.
[0067]
Copy mode 2: Forcibly transition to the specified screen. This is applied when the creation of a new window is permitted but it is necessary to make a forcible transition to the initial screen of the business processing logic. In this case, a new window ID is assigned, and only the definition (format) of the data store associated with the window ID of the copy source screen is copied, and the content (content) of the data store is not copied. Then, the business processing logic is activated to acquire the screen display data.
[0068]
Copy mode 3: Creation of a new window is not permitted. When the server 27 has a forced erasure screen (for example, a screen displaying a message such as “Forcibly erase due to creation of an inappropriate new window”), the server 27 forcibly erases the web browser 26. Send screen and do not start business logic or duplicate data store.
[0069]
Based on the above preparations, various operations of the web browser 26 are processed as follows.
[0070]
Whether or not a new window has been opened (whether or not the screen has been copied) can be detected by the web browser 26 when the web browser 26 displays the screen.
[0071]
When a web browser newly opens a window, the window name of the window becomes “Null”. Generally, the web browser is created so that the window name can be identified. Therefore, the web browser 26 checks the window name of the window at the start of displaying the screen, and if the window name is "Null", The corresponding request is transmitted to the server 27 according to the copy mode setting value of the screen.
[0072]
When the copy mode setting value is 1, the web browser 26 requests the server 27 to assign a new window ID with the window ID of the copy source screen attached. In response, the server 27 assigns a new window ID, duplicates both the definition and the content of the data store associated with the window ID of the transmitted copy source screen, and transmits the duplicate to the web browser 26. . As a result, the web browser 26 adopts the window ID newly assigned by the server 27 as the window ID of the newly opened window, and also takes over the data contents. Stores are synchronized.
[0073]
When the copy mode setting value is 2, a request is made to the server 27 for the forced transition destination URL set in the web page. On the other hand, the server 27 assigns a new window ID, duplicates only the definition of the data store of the forced transition destination, associates it with the new window ID, starts the business processing logic, and acquires the screen display data. I do. The web browser 26 adopts the window ID newly assigned by the server 27 as the window ID of the newly opened window, and displays a screen of the execution result of the business processing logic.
[0074]
If the copy mode setting value is 3, a request to delete the window ID is transmitted from the web browser 26. The server 27 transmits a forced erasure screen to the web browser 26, and the web browser 26 allows the user to perform a browser erasing operation.
[0075]
The window ID may be numbered by a web browser instead of by the server.
[0076]
In order to assign a window ID in the web browser, a menu system for an application is provided in the web browser, and the menu system controls the activation of the window of the web browser and assigns the window ID.
[0077]
According to this method, the time required for transmitting a window ID request to the server side and causing the server to process the window ID and return it is eliminated, the response performance when a new window is started is improved, and the function of the web browser is improved. Can be restricted.
[0078]
In some cases, a user directly inputs a URL in a web browser. In this case, when the window ID is not transmitted, even if the transmission source screen is defined with the copy mode setting value of 1, a new window ID is set and a data store is defined only, and another area is created. Manage with. This operation is performed in the same window, and does not open a new window. However, since a new session between the web browser and the server can be considered to have started, a new area is created. If the user performs a “return” operation to return to a previous page and sends a request, the window ID is set for that page, and data processing is performed without inconsistency on the returned page. You can start.
[0079]
【The invention's effect】
As is apparent from the above description, according to the data management method of the web browser utilization processing system of the present invention, the data area management unit is generated as a window unit, a frame page unit, and a data store unit from the upper level, and HTML Since the minimum unit of the page and the management unit of the data store are the same, it is possible to handle multiple windows even if you launch multiple windows on a web browser and process multiple application software simultaneously. The data store can be allocated, and no data error occurs.
[0080]
Further, according to the present invention, the data area of the corresponding window ID is released when the instruction to delete the data area is received from the application software, or the window whose setting retention time has passed when the request is received from the web browser is received. Since the data area of the ID is released or the entire data area of the session after the session valid time is released, the data area is not expanded and an excessive load is imposed on the session.
[0081]
According to the present invention, a plurality of screens whose screen transitions are defined according to the definition of the business processing logic are provided, each screen is assigned a copy mode setting value, and a new window ID is generated by operating a web browser. And all data stores associated with the window ID of the copy source screen are duplicated and associated with the new window ID, or a new window ID is generated and associated with the window ID of the copy source screen. After duplicating only the store definition, the business process logic is activated to acquire the screen display data, or the web browser is forcibly erased.
[0082]
As a result, in the web browser usage processing system, business processing can be performed, and even if an operation such as "create new window" or "return" is performed using the function of the web browser, correct data is displayed in each window or frame. The processing result can be displayed.
