DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-level data processing apparatus such as a database server and a low-level data processing apparatus such as a workstation connected to a LAN (Local Area Net).
The present invention relates to a data processing system such as a client server system connected by a communication network such as work), and a data processing device and method thereof.

[0002]

2. Description of the Related Art Hitherto, a client server system or the like, which is a data processing system in which a database server as an upper data processing apparatus and a workstation as a lower data processing apparatus are connected via a communication network such as a LAN, has been generally used. I have. In such a client-server system, the database server includes a database, and the database stores a large number of data files each having a key value set individually.
Further, the workstation has, for example, a function of receiving an access request by a keyboard input operation or the like and a function of executing an access process to the database server in response to the access request by a predetermined application program or the like.

In the above-described client-server system, for example, when a user inputs a desired access request to a workstation with a desired data file stored in a database of a database server, the workstation accesses the client. An access process is performed on the database server in response to the request, and the database server retrieves a data file corresponding to the access request from the database and executes the corresponding data process.

[0004] By such a processing operation, for example, a keyword search for a desired data file of a database server to refer to it or a text search of a desired data file by a keyword to add a text can be performed by a workstation. It can be realized by an input operation.

[0005]

In the client-server system as described above, desired data processing can be executed from the workstation to the data file of the database server.

When such a client server system is shipped to a user as a product, it may be necessary to provide the user with the response of the above-described processing operation as one of the specifications. In such a case, conventionally, a response measurement in an emulation environment or a simulation calculation of a response by a model formula is executed.

However, since these methods do not reflect the actual use environment of the user, it is difficult to provide an accurate response to the user. In addition, in any case, if the scale of the client-server system is large, enormous cost is required, so that its practicality is low.

For example, if a dummy data file is stored in a database server, a dummy access request is input to a workstation, and a response of the access processing is measured, a response reflecting an actual use environment can be measured. It is. However, this is not practical because a large number of access requests must be input to the workstation and the responses must be measured every time.

The present invention has been made in view of the above problems, and measures a response when a lower data processing device accesses an upper data processing device in a state corresponding to an actual use environment. It is an object of the present invention to provide a data processing system, a data processing apparatus and a data processing method thereof.

7, a log generation unit 18, a log storage unit 19, an operation control unit 20, a result output unit 21, and the like are logically provided.

The access execution means 12 includes the ROM
103 corresponding to the control program set in
When the PU 101 executes a predetermined processing operation, the PU 101 accesses the database 11 of the database server 2 in response to the access request. The access request input to the access execution unit 12 in this manner has, for example, a structure in which the processing contents are combined with the key values, and is input by the keyboard 110.

More specifically, when an access request is input to the keyboard 110 of the workstation 3,
The CPU 101 of the workstation 3 executes data communication with the database server 2 by the communication I / F 113 in response to the access request. In the database server 2, the CPU 101 executes the access process in response to the data received by the communication I / F 113. Therefore, a data file corresponding to the key value of the access request is searched from the database 11, and the searched data file is searched. Data processing corresponding to the processing content of the access request is performed on the data file. The processing contents of such an access request are as follows.
For example, it is set as updating or deleting a data file, and the processing result is returned from the database server 2 to the workstation 3.

The key value extracting means 13 is provided in the ROM 1
03 corresponding to the control program set to 03 or the like.
The U101 executes a predetermined processing operation to collect all key values from the database 11 of the database server 2.

More specifically, when a response control process is started by an input operation of the keyboard 110 in a state where a predetermined control program is set in the ROM 103 or the like of the workstation 3, the workstation 3 Of the communication I / F 113
Executes data communication for key value extraction to the database server 2. In the database server 2, the CPU 101 responds to the data communication of the communication I / F 113.

The key value conversion means 14 is also provided in the ROM 1
03 corresponding to the control program set to 03 or the like.
By performing a predetermined processing operation by U101, a large number of key values collected and returned as described above are totaled,
These key values are converted into a predetermined format. The process of totalizing and converting key values in this manner is performed by the workstation 3
To speed up the handling of key values in, for example, removing duplicate key values, sorting multiple key values, compressing multiple key values, converting key value formats,
And so on.

The key value holding means 15 is provided in the RAM 1
It is formed as a predetermined storage area of an updatable information storage medium such as 04, and holds a large number of key values compiled and converted as described above. The request generation means 16 comprises:
The CPU 101 executes a predetermined processing operation in accordance with the control program set in the ROM 103 or the like, thereby randomly extracting an arbitrary key value from the key value holding unit 15 and storing the predetermined processing content therein. Generate an access request with the addition. At this time, since the same key value is not repeatedly extracted, processes such as data deletion and flag setting are performed on the extracted key value.

Similarly, when the CPU 101 executes a predetermined processing operation in accordance with the control program set in the ROM 103 or the like, the access control means 17 responds to the access request generated as described above. It causes the access execution means 12 to execute an access process. As described above, since the processing result of the executed access processing is returned from the database server 2 to the workstation 3, the history generating means 18 generates history data corresponding to the processing result of the access processing. The history data is generated so that the response of the access processing can be measured. For example, the history data is generated as a data file in which the start time and the end time are added to the processing content of the access processing.

The history storage means 19 is also provided in the RAM 10
4 and the like, and is formed as a predetermined storage area of an updatable information storage medium, and sequentially stores a plurality of pieces of history data generated as described above. The operation control means 20 executes the request processing means 16 and the access control means 17 by the CPU 101 executing a predetermined processing operation in accordance with a control program set in the ROM 103 or the like.
And the history generation means 18 and the history storage means 19 are repeatedly operated.

The operation control means 20 sets the number of repetitions described above in advance, and notifies the result output means 21 of the completion of the processing when the integration number reaches the set number. The result output means 21 reads a plurality of pieces of history data stored in the history storage means 19 in response to the notification of the completion of the processing, and for example, averages the required time for each content of the access processing and outputs the response data. The report is generated and output as a report on the display 112 or the like.

The various means of the workstation 3 as described above are realized by using hardware such as the communication I / F 113 if necessary.
04 corresponding to the software written in
This is realized by the operation of U101. The above-described software of the workstation 3 is divided into a control program for access processing required when the user uses the client server system 1 and a control program for response measurement unnecessary when the user uses the client server system 1. You.

Therefore, in the client server system 1 of the present embodiment, the response measurement is executed with the control program for the access processing and the response measurement installed before the product is shipped to the user. At the time of shipment as a product, the response measurement control program is deleted and only the access processing control program is installed.

The software for the access processing of the workstation 3 as described above is transmitted from the communication I / F 113 to the database server 2 in response to the access request, for example.
The processing is described as a control program for causing the CPU 101 or the like to execute processing operations such as accessing the database 11 and receiving a processing result returned from the database server 2 to the communication I / F 113. . Also, the response measurement software of the workstation 3 collects all key values from the database 11 of the database server 2, for example, collects a large number of the collected key values and converts them into a predetermined form, Storing a large number of key values converted and compiled in a predetermined area of the RAM 104; generating an access request by randomly extracting an arbitrary key value from the held large number of key values; Inputting the generated access request to the software for the access processing to cause the database server 2 to execute the access processing; generating history data corresponding to the processing result returned from the database server 2; Sequentially storing a plurality of pieces of history data in a predetermined area or the like of the RAM 104; The processing operation from generation of such an access request to storage of history data is repeated up to a predetermined number of times. When the predetermined number of repetitions is completed, a plurality of stored history data are read out, response data is generated, and the The CPU 1 performs processing operations such as outputting a report using
01 is described as a control program to be executed.

In the configuration described above, the client server system 1 according to the present embodiment has the access processing control program installed but the response measurement control in the state of being shipped to the user as a product as described above. The program is not installed.

In this state, for example, when a user performs an input operation on the workstation 3 to create a data file, the data file is stored in the database 11 of the database server 2. When a large number of data files are stored in the database 11 as described above, for example, when the user inputs an access request such as reference to a data file on the workstation 3, the transmission data corresponding to the request is transmitted to the access execution unit. Data communication is performed from the workstation 3 to the database server 2 by the server 12. Then, the database server 2 stores the data file corresponding to the access request in the database 1
Since the data is retrieved from 1 and returned to the workstation 3, the user of the workstation 3 can refer to a desired data file.

As described above, in the client server system 1, the workstation 3 and the database server 2 execute the access processing in response to the access request, and a response of the access processing is provided to the user who purchases the client server system 1. Sometimes. In such a case, a dummy data file is stored in the database server 2 of the client server system 1 before being shipped as a product, and a control program for response measurement is installed in the workstation 3 to execute response measurement of access processing.

More specifically, when the start of response measurement processing is input to the workstation 3 by the keyboard 110 in the above-described state, the C of the workstation 3 is operated.
The PU 101 sequentially operates as various units 12 to 21 according to a response measurement control program. That is, all the key values are collected from the database 11 of the database server 2 by the key value extracting means 13 (Step S).
1) The key values are tabulated by the key value conversion means 14 and converted into a predetermined form (step S2), and held by the key value holding means 15 (step S3). The key value thus held is randomly extracted by the request generation means 16 (step S4), and a predetermined processing content is added to generate an access request (step S5).

The access request generated in this way is input to the access execution means 12 by the access control means 17, and the access execution means 12 executes the access processing in the same manner as in a normal case (step S6). Therefore,
The database server 2 searches the database 11 for a data file corresponding to the access request and executes data processing. The processing result is returned to the workstation 3. In the workstation 3, history data is generated by the history generation means 18 in accordance with the returned processing result (step S7), and the history data is stored in the history storage means 19 (step S8).

The processing operation from the generation of the access request to the storage of the history data as described above is performed by the operation control means 2.
0 is repeated up to a predetermined number of times (step S9). When this repetition is completed, the response of the access processing is measured by the result output means 21 from a large number of accumulated history data, and this response is notified and output on the display 112 or the like. Is done.

In the client server system 1 according to the present embodiment, the access process is actually executed in the state before the product is shipped as described above, similarly to the use state of the user, and the access process actually executed in this manner is performed. Is measured, it is possible to accurately measure the response in the usage environment of the user. In addition, since an access request required to execute such a response measurement is automatically generated from a key value of a data file stored in the database 11, an operator creates an access request when measuring a response. Therefore, it is not necessary to perform an input operation with the keyboard 110, and the response measurement can be easily performed.

When the response measurement of the access process is performed as described above, the data file actually used by the user is stored in the database 11, and the application program used by the user is stored in the database server 2.
If it is installed in the workstation 3, the response corresponding to the usage environment of the user can be more accurately measured.

Moreover, in the client-server system 1 of the present embodiment, the various means 12 to 21 necessary for measuring the response are located in the workstation 3, so that unnecessary processing load is imposed on the database server 2 when measuring the response. Since it has no effect, the response of the access processing can be accurately measured. However, since the key value extracting means 13 and the key value converting means 14 do not need to be operating when executing the response measurement, these means 13, 1
4 can accurately measure the response of the access processing even if it is provided in the database server 2.

Further, in the client-server system 1 of the present embodiment, the key values collected from the database 11 by the key value extracting means 13 and held in the key value holding means 15 are compiled by the key value converting means 14. Since the data is converted into the predetermined form, the load on the access request generation processing by the request generation unit 16 can be reduced and the speed can be improved.

The present invention is not limited to the above-described embodiment, but allows various modifications without departing from the scope of the invention. For example, in the above embodiment, C is executed according to a control program stored as software in the RAM 104 or the like.
An example has been described in which various units of the workstation 3 are realized by the operation of the PU 101. However, it is also possible to form each of the various means as unique hardware, and a part of the means is implemented as software.
It is also possible to store it in the AM 104 or the like and form a part of it as hardware.

For example, in the client server system 1 of the above embodiment, the response measurement control program is temporarily installed in the workstation 3 actually shipped to the user, but such a control program is fixedly installed. It is also possible to create a data processing device (not shown) for measuring the set response and temporarily connect it to the client server system 1 to be shipped to the user to measure the response of the database server 2. It is.

In the above embodiment, the workstation 3
Is started, the software stored in advance in the HDD 105 is copied to the RAM 104, and
It is assumed that the CPU 101 reads the software stored in the HDD 04.
It is also possible for the CPU 101 to use the data stored in the storage unit 105 or to fixedly write the data in the ROM 103 in advance.

Further, software is written in the FD 106 or the CD-ROM 109 which is an information storage medium that can be handled alone, and the FD 106 and the RAM 104
It is also possible to install software in the FD1 or the like without executing such an installation.
It is also possible for the CPU 101 to directly read the software from 06 or the like and execute the processing operation.

That is, when the various means of the data processing system of the present invention are realized by software, the software only needs to be in a state where the CPU 101 can read and execute the corresponding operation. It is also possible to form a control program for realizing the various means as described above by combining a plurality of software. In this case, the information processing medium of the present invention includes the data processing system of the present invention as a single product. It is only necessary to store only the minimum necessary software for realization.

For example, the database server 2 on which an existing operating system is mounted has a CD-RO
In a case where application software is provided by an information storage medium such as M108, software for implementing various means of the data processing system of the present invention is implemented by a combination of application software and an operating system, and thus depends on the operating system. Part of the software can be omitted from the application software of the information storage medium.
