Embodiment
For the purpose, technical scheme and advantage of the embodiment of the present invention are more clearly understood, below in conjunction with the accompanying drawings to this hair
Bright embodiment is described in further details.Here, the schematic description and description of the present invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
Inventor is had found, in batch process, many scenes are needed tables of data UNLOAD into file.In this mistake
System can automatically generate the data structure that a SYSPUNCH file is used for describing UNLOAD files in journey.This file often by
Ignore.Based on this, the method that data structure dynamic generation in a kind of main frame is provided in embodiments of the present invention, SYSPUNCH is utilized
The related parameter of application is processed into the COPYBOOK of UNLOAD files by file, in follow-up documentor, avoiding
It is manually generated and safeguard COPYBOOK.
Fig. 1 is the method schematic diagram of data structure dynamic generation in main frame in the embodiment of the present invention, as shown in figure 1, the party
Method can include：
Step 101, pending data table downloaded into data file, and obtain SYSPUNCH corresponding to the data file
File, the SYSPUNCH files describe the data structure of the data file；
Step 102, the first parameter is obtained, first parameter describes the processing mode of aiming field and aiming field；
Step 103, using the SYSPUNCH files first parameter is processed into the second parameter, second parameter
The processing mode of the position and aiming field of aiming field, aiming field in the data file is described；
Step 104, according to second parameter data file is handled.
The first parameter is processed into by flow it is known that in the embodiment of the present invention using SYSPUNCH files as shown in Figure 1
Second parameter, data structure dynamic generation in main frame is realized with this, Development and Production rate can be improved, and change in follow-up data table
When Maintenance free COPYBOOK, reduce maintenance workload；Handled according to the second parameter logistic according to file, multiplexing can be improved
Property, it is not necessary to different cobol programs is write when different tables per treatment to handle, so as to improve the effect that exploitation is safeguarded
Rate.
When it is implemented, first downloading pending data table into data file, and obtain corresponding to data file
The data structure of SYSPUNCH files, wherein SYSPUNCH document description datas file.
A naive model of processing data storehouse data can be divided into 2 steps in batch：
1st, by pending table UNLOAD into file format；
2nd, UNLOAD file is subjected to file process.
During UNLOAD is into file, system can automatically generate a SYSPUNCH file, and this document describes data
Table UNLOAD is into the data structure after file.An example of SYSPUNCH files is given below：
Need to obtain the first parameter during implementation, the first parameter describes the processing mode of aiming field and aiming field.Such as
Design a first parameter A, field and processing mode involved by description application (or demand).In one example, the first parameter
It can include：Table name, aiming field sequence number, aiming field name, aiming field location expression, aiming field data type, target
The processing mode of field.Certainly, the concrete structure of the first parameter can have different structure designs according to the difference of application.
, it is necessary to which two fields of INVM tables are desensitized so that sensitive data desensitizes as an example, the first parameter A of table knot
Structure design example is as follows：
First row is table name, and secondary series is sequence number, and the 3rd row are the location expressions of field name+field portions content, the 4th
Row describe the data type of field to be desensitized, and the five, the six row are major class+subclasses of desensitization.It is understood that different application
Corresponding first parameter A may have different structure designs.
As described above, the first parameter A describe desensitization demand INVM tables of interest 2 fields (KEY_1 and
CUSTOMER_NO data manipulation method).
During implementation after the first parameter is obtained, the first parameter is processed into the second parameter using SYSPUNCH files, wherein
Second parameter describes the processing mode of aiming field, aiming field position in the data file and aiming field.Due to
The data structure of SYSPUNCH document description data files, therefore the first parameter can be processed into using SYSPUNCH files
Two parameters.For example, the position of aiming field in the data file can be determined according to SYSPUNCH files；By by target word
The position of section in the data file adds the first parameter and obtains the second parameter.In one example, the second parameter can include：Table
Name, aiming field sequence number, aiming field name, aiming field location expression, aiming field data type, the processing side of aiming field
Formula, the position of aiming field in the data file.Certainly, the concrete structure of the second parameter can also have not according to the difference of application
Same structure design.
In one example, the position of aiming field in the data file, can include：Of aiming field in the data file
Beginning position and end position.Certainly, the position of aiming field in the data file can also use other modes to describe, such as mesh
Marking-up section original position in the data file and field length etc..
Still by taking the desensitization of above-mentioned sensitive data as an example, according to SYSPUNCH files and the first parameter A, it can be learnt by calculating
Position of 2 fields in UNLOAD files in first parameter A, so as to process to obtain the second parameter B, the second parameter B examples
It is as follows：
20170306 INVM 000 000 Y
N|001|KEY_1 |X| |01|01|00006|00021|
N|002|CUSTOMER_NO |X| |01|01|00088|00103|
In the second parameter B, the original position and end position of field in the first parameter A are supplemented.
As described above, the first parameter is processed into the second parameter using SYSPUNCH files, equivalent to utilizing SYSPUNCH
The related parameter of application has been processed into the COPYBOOK of UNLOAD files by file, without a newly-built UNLOAD file
COPYBOOK, you can realize data structure dynamic generation in main frame.
After the first parameter is processed into the second parameter, handled according to the second parameter logistic according to file.In embodiment,
Aiming field can be found according to the position of aiming field in the data file in the second parameter, in the data file positioning；Root
According to the processing mode of aiming field in the second parameter, aiming field in data file is handled.Still with above-mentioned sensitive data
Exemplified by desensitization, follow-up data processor (being desensitization in this example) can position according to the second parameter B field finds the word
Section, and according to the data processing mode appointed, data are handled, final data file C can be obtained.
In the above-described embodiments, the first parameter A can be processed into using SYSPUNCH files and meets that cobol program is processed
It is required that the second parameter B, design cobol program, the behavior pattern of field and field in the second parameter B, by UNLOAD
File is processed into final data file C.On stream, the first parameter A structure design can expire according to the actual requirements
The processing requirement of the various data types of foot (including exception data).
Based on same inventive concept, a kind of dress of data structure dynamic generation in main frame is additionally provided in the embodiment of the present invention
Put, as described in the following examples.The method for solving data structure dynamic generation in the principle of problem and main frame due to the device
It is similar, therefore the implementation of the device may refer to the implementation of the method for data structure dynamic generation in main frame, repeat part no longer
Repeat.
