Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device, and more particularly to a data processing device capable of efficiently processing data by combining programs in a plurality of programming languages.

[0002]

2. Description of the Related Art With the development of the Internet, commercial transactions (electronic commerce) via the Internet are increasing. When performing this electronic commerce, the server executes a program (business program) written in a programming language such as C ++ for processing (business) data on the actual commercial transaction.
And a home page, screen, etc. described in HTML (HyperText Markup Language). The client performs business by accessing the homepage and inputting predetermined items into the homepage.

[0003]

In electronic commerce, the quicker the response from the server after the client inputs predetermined items on the screen and sends it to the server, the better.
However, in reality, a data processing system capable of responding at such a high speed that all or part of the work can be performed by electronic commerce has not been developed. For example, if the response time is 1 to 2 seconds, all or part of the work can be performed by electronic commerce, but the actual response time is 5 seconds or more per screen in reality.

According to a study by the present inventor, all jobs can be executed by a combination of a limited number of types of processing (file reference, update, calculation, selection, link, etc.). Therefore, the limited types of processing are realized by preparing a small number of small programs that each execute only one type of processing. Then, one work is performed by preparing a plurality of small programs that each perform only one different process and continuously executing these. By doing so, it is considered that the processing of the business can be completed at high speed.

However, as a result of further study by the present inventor, it was found that such a data processing configuration cannot be applied to the processing of business in electronic commerce using the Internet as it is for the following reason.

First, as shown in FIG. 4, usually, in the processing using the Internet 200 in the business server 100, the script 400 written in HTML from the client 300 is executed by the CGI program 101 written in C ++ language. Interpretation is performed, and based on this, the ".exe program" that actually performs data processing from the CGI program 101, that is, the processing program to which the extension ".exe" is added is started. Therefore, it is assumed that a certain work can be executed in combination with the process A and the process B. Then, an .exe program 102A written in the C ++ language that executes the process A (only) and an .exe program 102B written in the C ++ language that executes the process B (only) are prepared. However, due to the restriction of the C ++ language, only one .exe program 102A can be started from the conventional CGI program 101, and then the .exe program 102B cannot be started. Therefore, it is impossible to continuously execute a small program that executes only one different process.
Therefore, the business processing cannot be performed by such a data processing configuration.

It should be noted that only one .exe program can be started from a CGI program.
This is because it is premised that the program completes the processing corresponding to one screen on the Internet. Therefore, even if an attempt is made to subdivide the processing corresponding to the screen, it cannot be subdivided. In other words, conventionally, it has not been planned to subdivide the processing corresponding to the screen.

Second, in the case of business processing, the .exe program 102A or the like is the RDB provided in the host computer.
Since a lot of processing is executed using the (relational database), it takes a considerable time from its start up to its end. Therefore, it is practically impossible to leave the history information that is indispensable for the processing of the business. That is, even though only the original process is slow, executing the process that leaves the history information on top of this causes a further decrease in processing speed. Therefore, the program 10 does not need to retain history information about the processing executed by the program 102A.
It only returns the result of 2A processing.

It is an object of the present invention to provide a data processing device which enables data processing with high processing efficiency by combining programs in a plurality of programming languages.

[0010]

A data processing apparatus according to the present invention comprises a first program for starting a second program by a command for badge processing based on an input script, and a first program provided with a plurality of small programs. A second program that is activated by a badge processing command to execute a plurality of small programs in a predetermined order and then returns to the first program to output a response script as a response to the input script. The first program is the first
, The second program is written in the second language, and the input script and the response script are written in the third language. Each of the plurality of small programs executes only a predetermined operation on a predetermined file.

According to the data processor of the present invention, for example, the CGI described in C ++ which is the first program.
It is possible to interpret the input script written in HTML by the program and activate the second program that actually performs the data processing from the CGI program by the badge processing instruction (the activation instruction of the ".bat program"). As a result, it is possible to sequentially execute a plurality of small programs that execute only a predetermined operation on a predetermined file. Therefore, one business is prepared by combining a plurality of small programs that execute only one different process,
The configuration of data processing that is performed by continuously executing these can be directly applied to the processing of business in electronic commerce using the Internet. As a result, the processing of the business can be completed at high speed. For example, after the client inputs a predetermined item on the screen and sends it to the server, the response time from the server can be set to, for example, 1 to 2 seconds. For example, all or part of the work is performed by electronic commerce. be able to. Further, since such high-speed business processing is possible, history information about the executed processing can be left for each of the plurality of small programs that execute the actual processing.

1 is a block diagram of a data processing system, showing a structure of a data processing apparatus according to the present invention.

The data processing system comprises a computer that is a server (business server) 1 that performs business such as ordering products, and a computer that is a client 3 that orders products. The business server 1 and the client 3 are connected to each other via the Internet 2. Business server 1
Includes a first program 11, a second program 14, a business file 17, and a history information file 18.

The first program 11 is a CGI program written in a first language, for example, C ++ (hereinafter referred to as "CGI program").
The CGI program 11) and the input script 4 written in HTML are interpreted to start a business program (second program 14) that performs actual processing. That is,
Based on the input script 4 transmitted from the client 3, the CGI program 11 activates the second program 14 designated in the input script 4 by a command for badge processing. The badge processing instruction activates a .bat program for executing the badge processing, that is, a badge processing program (second program 14) to which the extension “.bat” is added.

The input script 4 is a program written in the language (third language) used in the Internet 2, that is, HTML. The input script 4 is, as described above, one second program 14 that executes an actual job.
Including a name ".bat # 1" of the second program 14, for example. The input script 4 is an input / output screen of the CGI program 11, and is actually an input screen for inputting information about the operation on the file 17 in the second program 14 described in HTML (script). Similarly, in the response script described later, an output screen for displaying the result of the operation is described in HTML.

The CGI program 11 includes a boot processing unit 12
And a management file 13. CGI Program 11
Takes out the name “.bat # 1” of the second program 14 described at a predetermined position of the input script 4 and passes it to the activation processing unit 12. The activation processing unit 12 refers to the management file 13 using the name, obtains the storage location thereof, and executes the process of activating the second program 14 having the name “.bat # 1”. That is, the management file 13 stores the storage locations corresponding to the names of the plurality of second programs 14.

Here, when the business server 1 carries out a plurality of jobs, a plurality of business programs 14 for actually executing the respective jobs are prepared. In this specification, “one job” means performing at least one operation (reference, writing (overwriting), updating, etc.) of the job file 17.
In a typical so-called product ordering business, reference and updating are often repeated, so one or a plurality of business programs 1
It is realized (processed) by the execution of a plurality of tasks according to 4.

When the second program 14 is activated by the CGI program 11, the second program 14 performs actual business processing (hereinafter referred to as business program 14). Business program 14
Is provided with a plurality of small programs 15, is activated by a badge processing command from the CGI program 11, and executes the plurality of small programs 15 in a predetermined order. That is, the plurality of small programs 15 are executed with a badge. After that, the business program 14 passes the processing result to the CGI program 11 and returns, and outputs the response script. For this restoration processing, the business program 14 includes a restoration processing unit 16. The response script is a response to the input script 4 and has a content according to the processing result. The business program 14 (that is, the plurality of small programs 15) is written in the second language. The second language is a simpler language than the first language. For example, the second language is XML.

Therefore, C consisting of C ++ which is a high-level language
Although the creation of the GI program 11 must be entrusted to an expert, the business program 14 is a simpler language and thus can be easily created. Since the business program 14 for executing the actual business can be easily created in this manner, the business server 1 can be easily configured as a whole.

Each of the plurality of small programs 15 executes only a predetermined operation on a predetermined file (hereinafter, business file) 17. That is, the operation for the predetermined file 17 is described. According to the description of the small program 15, the business file 17 used by the small program 15 is predetermined, and the process (file operation) executed by the small program 15 is also predetermined. Actually, one small program 15 is one command. As described above, since only a few types of limited processing are combined, the number of small programs or commands to be prepared is also limited. Therefore,
No complicated control description is required, and a small program or command can be configured with a very simplified description.

The business file 17 is used for business processing by the business server 1, and includes, for example, a member file for registering members, a product master file for storing product information, an inventory file for storing product inventory information, and the like. The file operation includes, for example, reference, update, and overwrite. For example, the small program 15 performs a task of referencing the member file (reference task) or a task of registering a member in the member file (writing or overwriting task).

Here, when the small program 15 is a program for executing the "reference" work, the small program 1
Reference numeral 5 performs a task (information processing) of reading and displaying information in the task file 17 that is determined to be used by the file.
When the small program 15 is a program that executes a "writing" job, the small program 15 performs a job of writing (overwriting) information in the job file 17 that is determined to be used by the small program 15. When the small program 15 is a program that executes “update” work, the small program 15 continuously performs the reference work and the writing work for the work file 17 that is determined to be used by the small program 15.

Each of the small programs 15 executes a predetermined job and writes the history of the processing in order from the beginning of the job history file 18. That is, the business history file 18 is used to record the history of the business executed by the business server 1, and is used for each client 3 and the small program 1.
Time information (start / end time of processing such as date, time, etc.) of the business, the name of the business file 17 used for the business, the content of the business such as reference, confirmation input of the business for each 5 Information such as the presence or absence of is stored.

When the second program 14 receives the necessary data from the CGI program 11 and is activated, the second program 14 is activated by passing the data to the small program 15 which is determined to be executed first. Each of the small programs 15 executes a predetermined process using the business file 17 defined by using the data, writes the history information 18A and the like in the business history file 18, and processes it in another defined program. Start by passing the required data, including the result. The other program determined to be activated is the small program 15 determined to be executed next. As a result, the plurality of small programs 15 are executed with the badge. However, the small program 15 determined to be executed last is
It is determined to activate the return processing unit 16. That is, the last small program 15 passes necessary data including the processing result to the restoration processing unit 16 and starts it. The activated restoration processing unit 16 passes the processing result to the CGI program 11,
Instruct to output the response file written in HTML,
The process ends. As a result, the control returns to the CGI program 11, and the response script is output based on the processing result.

FIG. 2 shows a data processing flow, showing data processing in the data processing apparatus of the present invention.

The CGI program 11 of the business server 1 is
When the access from the client 3 is received (step S11), the HTML file of the menu screen (not shown) (same for the following screens) is returned to the client 3 (step S12). On the menu screen, for example, operations such as "reference (of products in stock and quantity)", "update (of quantity of stock)" (order) (order of products (execute reference and update continuously)), etc. Is displayed so that you can select it. Therefore, the client 3 selects and inputs a predetermined task (for example, reference) from the menu screen and sends it back, and the CGI program 11 receives it (step S13).

In response to this, the CGI program 11
The input screen for the work (the input field of the input script 4 is blank) is returned to the client 3 (step S14). In the input screen, for example, if it is a reference input screen, you can enter the "product name", or
Multiple product names are displayed so that you can select from them. Therefore, the client 3 inputs (or selects) a predetermined item in the input field of the input screen,
It is returned as the input script 4, and the CGI program 11 receives it (step S15). At this time, if the input script 4 is, for example, the reference input script 4, as shown in FIG. 1, the product name “.bat # 1 (name of the business program 14)” is included. "Product name" is
This is the information entered by the client 3, and the relevant ".bat # 1"
It is included in, for example, an “inventory” business file 17 that is defined to be used by the business program 14. ".Bat # 1"
Indicates that what was previously included in the reference input screen transmitted by the CGI program 11 is also included in the input script 4 as it is, and indicates the program that executes the reference task.

Upon receipt of the input script 4, the CGI
The program 11 retrieves necessary information including the name of the business program 14 from the input script 4, refers to the management file 13 using the name, and obtains the storage location of the business program 14 (step S16). The necessary information taken out is passed to the business program 14 and activated (step S17). For example, according to the above-mentioned example, the CGI program 11 extracts the “commodity name” and “.bat # 1” from the input script 4 and outputs “.bat # 1”.
The management file 13 is referred to using the storage location “#A
"100" is obtained, the "product name" is passed to the business program 14 of ".bat # 1", and this is started.

[.Bat # 1] business program 14 started
Passes the retrieved necessary information to the first small program 15A and activates it (step S18). The small program 15A executes a predetermined process using the business file 17A defined by using the data (step S19), and stores the history information 18A in the business history file 1
8 (step S20). After that, the activation of the next small program 15 (step S18), the predetermined processing (step S19), and the recording of the history information 18B, ... (Step S20) are repeated for the number of small programs 15.
Also for the last small program 15N (not shown), after its activation (step S18), similarly, predetermined processing (step S19) is performed, and after recording history information 18N (not shown) (step S20), step S18. Without repeating
Necessary data including the processing result is passed to the restoration processing unit 16 and activated (step S21). Recovery processing unit 1 that has been started
6 passes the processing result to the CGI program 11 and instructs the output of the response script (step S22).

The CGI program 11 to which control is passed is
A response script written in HTML is created based on the processing result (step S23), and this is sent to the client 3 (step S24).

For example, according to the above-mentioned example, the small program 15A uses the passed "product name" to refer to the product master file 17A to obtain the product code of the product,
The history information 18A is recorded. The history information 18A is, for example, information indicating the start and end times of processing such as the date and time when the relevant business was performed, the name of the product master file 17A, the facts referred to, the relevant product name, and the presence or absence of confirmation input for the relevant business Etc. Then, the small program 15A passes the product code (and the "product name" if necessary) which is the processing result to the small program 15B and activates it. The reference to the product master file 17A can be executed in an extremely short time because it refers to one file with one key. The recording of the history information 18A can also be executed in an extremely short time because it is writing to a predetermined position (the head of a free area) of a predetermined file. The small program 15B can also be started up in an extremely short time because it is the start of one predetermined program. Therefore, the processing by the small program 15A described above can be executed in an extremely short time (the same applies to others).

The small program 15B uses the passed product code to refer to the stock master file 17B to obtain the stock quantity of (the product of) the product code, and records the history information 18A. After that, the small program 15B passes the stock quantity, which is the processing result, to the restoration processing unit 16 and activates it. The restoration processing unit 16 passes the stock quantity, which is the processing result, to the CGI program 11 and instructs the CGI program 11 to output the response script. Therefore, the CGI program 11 creates a response script that includes the “commodity name” that was initially taken out and the stock quantity that is the processing result, and sends it to the client 3.
As a result, from the perspective of the client 3, the task of referring to the stock quantity of a certain product can be executed in a short time.

FIG. 3 is an explanatory diagram of the data processing device.
3 shows another configuration of the business server 1 of the present invention.

When a certain business program 14 is executed in the business server 1, a plurality (1 or) history information 18A, 18B, ... As a result is left in the history information file 18. As a result, it is possible to know the execution time (time from the start to the end of the process) of each of the plurality of small programs 15 configuring the business program 14.

Therefore, the conversion processing unit 19 provided in the business server 1 executes a certain business program 14 once (or a plurality of predetermined times), and then the history information file 18
, And the history information 18A, 18B, ... About the business program 14 is extracted. This process may be executed according to an instruction input from the outside, or may be executed periodically. The conversion processing unit 19 obtains the processing time (each average processing time) of the small programs 15A, 15B, ... Based on the retrieved history information 18A, 18B ,. Then, for example, when the processing time of the small program 15A is longer than a predetermined value, the conversion processing unit 19 rewrites (converts) the small program 15A into a description in another language suitable for the processing. Create the program 21. The other language is, for example, C ++ which is a high level language. Further, the conversion processing unit 19 rewrites the small program 15A into a small program 15A ′ which calls the small program 21 without executing the processing and receives the processing result. As a result, as shown in FIG. 3, the business program 14 'starts the small program 15A' when it is started from the CGI program 11, and the small program 15A 'calls the small program 21 and receives the processing result. The processing result is passed to the small program 15B and activated. As a result, the business program 14 '
Is a program that executes optimum (higher speed) processing in which programs of multiple languages are mixed.

The manager of the business server 1 may execute the above processing. That is, after the administrator executes a certain business program 14 once (or a predetermined number of times), the history information 18A, 18B, ...
・ Read out the small programs 15A, 15B, ...
The processing time (average) of each of is calculated, and it is checked whether the average value is longer than the target processing time.
The small program 15A is rewritten (converted) into a description in another language, and the small program 15A is rewritten. In this case, the language suitable for the processing can be arbitrarily selected. Further, in this case, the conversion processing unit 19 converts the small program 15A into a description in another language, so that the small program 21A
May be created.
