Abstract

PURPOSE:To improve the function of sampling processing by providing a parameter input means which sets an extraction rate and an initial value of each data classification of extraction object data having plural data classifications and extracting sample data by this parameter. CONSTITUTION:A parameter input means 2 receives the extraction rate and the initial value of each data classification as parameter values from a console 1. A parameter analyzing means 3 verifies the validity of the parameter. The parameter is transferred to a data extracting means 5 together with data 4 as the extraction object. The data extracting means 5 generates a table in accordance with extraction rates and initial values and extracts data by matching to data as the extraction object. For example, when the extraction rate of a data classification A is 1/100 and the initial value is '1' and '5', 1st, 5th, 101st, 105th,... data are outputted as sampling data to a data file 7.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data sampling processing, and more particularly to a sample data sampling device adapted to a plurality of extraction conditions.

0002

[Prior Art] A conventional sample data sampling device has 1
Data sampling was performed by simply giving the extraction rate without giving the initial value for each type of data, and it was not possible to target multiple types of data at the same time.

0003

[Problem to be Solved by the Invention] The conventional sample data sampling device described above can only handle one type of data and cannot provide an initial value, so it cannot handle multiple types of data at the same time. However, there is a drawback that only the first data can be extracted at any time.

0004

[Means for Solving the Problems] A sample data sampling device of the present invention includes a parameter input means for setting an extraction rate and an initial value of sample data, and a parameter analysis means for verifying the validity of the extraction rate and initial value. , data extraction means for extracting sample data according to the extraction rate and initial value verified by the parameter analysis means, and extraction result output means for transmitting the extraction results of the data extraction means.

Further, the sample data sampling device of the present invention is configured to set extraction rates and a plurality of initial values for each of a plurality of types of data, and to extract sample data for each data type.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In the figure, the parameter input means 2 receives the extraction rate and initial value for each data type, which are parameter values, from the console 1 in the form of commands. The validity of the received parameters is verified by the parameter analysis means 3. The verified parameters are passed to the data extraction means 5 together with the data 4 to be extracted.

The data extraction means 5 creates a table based on the extraction rate and initial value given by the parameters, performs matching with data to be extracted, and performs extraction. Then, the extracted result is passed to the extraction result output means 6. The extraction result output means 6 outputs the extracted data to a data file. A series of extraction processes are executed in this manner.

FIG. 2 is an explanatory diagram showing the operation of the above sample data sampling device. In the same figure, console 1
When the parameter 8 is inputted from the parameter 8, a verification 9 of the validity of the parameter value is performed. Validity means that the value is numeric, the extraction rate is 3 digits, and the initial value does not change.

[0010] When input of parameters for all data types is completed, a parameter table is set. Based on this table 10, matching processing with extraction target data 11 is performed for each data type, and data extraction processing 12 is performed.

[0011] In the case of the same figure, the extraction rate is 1 in 100 for data type A data, and the initial value is "1" or "5".
Therefore, the 1st data, 5th data, 101st data, 105th data, etc. of the data with data type A of extraction target data 11 are the matching data, and are the sampling data. It is output as 13. In this way, data having a plurality of data types is sampled based on the respective given extraction rates and initial values.

0012

[Effects of the Invention] As explained above, the present invention has the effect of enabling more sophisticated sampling processing by setting different extraction rates and initial values for extraction target data having multiple data types. be. Therefore, there is an effect that a plurality of data can be extracted simultaneously without limiting the data to be sampled to one type.
