Abstract

PURPOSE:To improve the reliability of data conversion, by grouping all files in similar format having the same data attribute, and applying the same conversion parameter. CONSTITUTION:A parameter attribute table generation part 5 takes only attributes out of a data conversion parameter input file to generate a parameter attribute table 6. An identical attribute confirmation processing part 7 generate an identical attribute information file by grouping files having the same attribute parameter among all files. A source attribute table generation part 10, on the other hand, generates a source attribute table 11 from a source copy library 9. A parameter attribute checking part 12 makes a check by comparing the source attribute table with attribute patterns and outputs the check results to a parameter correction processing part 13. This processing part 13 analyzes the check results to make corrections. Thus, a data conversion processing part 14 applies the same conversion system to files having the same attribute for processing.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Summary of the Invention The present invention relates to a data conversion processing method when converging 7 files between A type systems, and particularly when the layout of files changes due to the convergence. , between files called JI4.

Group those with the same conversion parameter attributes,
High reliability can be achieved by applying the same conversion method in common.
The present invention relates to a data conversion processing method for simulative format files that allows converged conversion data with ij characteristics to be obtained.

Technical background When converging files between systems with different data representation formats, such as when converging files with other companies' computer systems,
Data length and column correspondence change, resulting in a different file layout, but at this time, data errors are likely to occur for various reasons.

Below, some examples of error occurrence will be explained.

In the example shown in A-1E, there was originally source data with a data field in FILLER, which was used to adjust the length and align digits of the repudo.

This is an example of a person converting data incorrectly without noticing the special rules.

■ is the data format provided by the user, and if it is converted into a standard format, it will be 9CMP (
9 is a number, CMP is compressed data) is converted to byte length data, and the rest are! ! Transition in the form of a man. However, as shown in (2), an exceptional rule was actually established in knee flIll, and a data item column of 9CMP was set in a part of FILLER. Therefore, if the conversion as shown in ■ is carried out, the data in FILLER will remain in compressed form, so it must be converted into the form as shown in ■.

The example shown in FIG. 2 is an example in which an unusual format occurs when converting multi-format data, especially data with a record classification at the end.

A and B represent two formats from the original multi-format. When they were converted into data, there was a difference in record length as shown in nF, so we changed the record length to A, which has a longer record length. Matching B
This is the result of adding all F I LLER to the end of P. However, in the original, the record classification is at the lowest level, and the position of this part must also be adjusted for the data after 'R conversion.

This will cause errors in record classification judgment. Therefore, FILLER must be added at the positions shown in and h.

The case shown in No. 31m is data transferred by the determination logic within the program, and particularly in the case of record units, data that has become longer due to conversion is cut off, resulting in an error.

In the same figure (-) is the original state, and (God) is the state after conversion.
In the original, A, B, and C have the same record length, so the 0 judgment logic indicates that A or B is C.
There is no problem even if the record is divided into two, but after conversion, the record length of B' and C# does not change in the data, so the judgment is 0 - Jeddah.

When A' or B' is transferred to C' by record classification.

The data on the protruding part on the steep side will be cut off. Therefore, the reflex lengths of B' and C' need to be matched.

Errors like the above cases occur during the Pumbarge process due to lack of preliminary investigation and analysis, which may be due to insufficient identification of program incompatibility and file area changes, or data conversion may be due to errors provided by the user. This is due to the lack of reliability as it relies solely on various documents.

On the other hand, since data cannot be transferred between files after convergence, it is important to improve reliability during data conversion.

The purpose and structure of the book @Ha is to solve the above-mentioned conventional problems.
The purpose is to generate data conversion parameters with 1i precision, and for this purpose, the data conversion parameters provided by the user are checked using definition information of the source program.

Files of similar formats with the same data attributes are all grouped together and the same conversion parameters are applied to improve the reliability of data conversion.

The present invention has a data conversion processing system that includes a means for creating a parameter attribute table based on data conversion parameters for every seven files serving as a conversion logarithm, and a means for creating a parameter attribute table based on a data conversion parameter for each of seven files, which is a conversion logarithm, and grouping frames of the same genus from the parameter attribute table for each file. means for creating a source attribute table from a source program that defines data to be converted; means for comparing and checking the source attribute table with the grouped parameter attribute table; , means for determining a parameter attribute table, and data conversion means, and the data conversion is characterized in that the same conversion process is executed for the seven tails of the same genus.

Actual Example of the Invention Fig. 4 shows the basic data source used for data conversion parameter generation in the present embodiment. be.

X (10) in the employee name represents the digit number f! [1 and the base salary of 9 (10) CMP represent a 10-digit number expressed in compressed half-bytes.

To explain about Figure 5, data conversion parameters are created from the user-provided file layout data shown in figure 6 and figure 4). The data conversion parameters are shown in Figure 4 (&
). On the other hand, data corresponding to the data conversion parameters is created by analyzing the 2-pol source and the frame data in the copy library.

Next, these two data conversion parameters are checked against the source data. If they match, the data conversion parameters are determined to be correct, and any unclear points are analyzed and the results are reflected in the data conversion parameters and others. Data conversion processing is performed using the finally obtained data conversion parameters.
