Abstract

A first data format may include real data. A second data format and a third data format each may include real data and metadata indicative of an attribute of the real data. The second data format may include the real data and the metadata in data units different from each other. The third data format may include the real data and the metadata in a single data unit. A program may cause a processor to convert, in response to an input data being in the first data format or in the third data format, the data format of the input data to generate output data in the second data format.

First claim

The invention claimed is:

1. A data processing apparatus for processing input data to generate output data, the apparatus comprising:
a memory configured to store a program; and
a processor configured to execute the program,
wherein the input data is in a first data format, in a second data format, or in a third data format,
the first data format comprises real data,
each of the second data format and the third data format comprises real data and metadata indicative of an attribute of the real data,
the second data format comprises the real data and the metadata in data units different from each other,
the third data format comprises the real data and the metadata in a single data unit, and
the program causes the processor to convert, in response to the input data being in the first data format or in the third data format, the data format of the input data to generate output data in the second data format.

2. The data processing apparatus according to claim 1 , wherein
the program further causes the processor to generate the output data in the second data format in response to the input data being in the second data format.

3. The data processing apparatus according to claim 1 , wherein
the program further causes the processor to output the real data included in the output data to an ETL tool being an extract, transform, and load tool.

4. The data processing apparatus according to claim 3 , wherein
the program causes the processor to process the metadata in accordance with a process performed on the real data by the ETL tool.

5. The data processing apparatus according to claim 1 , wherein
the real data comprises sensing data generated by a sensor.

6. A data processing method for processing input data to generate output data, the input data being in a first data format, in a second data format, or in a third data format,
the first data format comprising real data,
each of the second data format and the third data format comprising real data and metadata indicative of an attribute of the real data,
the second data format comprising the real data and the metadata in data units different from each other,
the third data format comprising the real data and the metadata in a single data unit, the method comprising:
converting, in response to the input data being in the first data format or in the third data format, the data format of the input data to generate output data in the second data format.

7. A non-transitory computer-readable storage medium storing a data processing program, which when read and executed, causes a processor to process input data to generate output data,
format of the input data comprising a first data format, a second data format, and a third data format,
the first data format comprising real data,
each of the second data format and the third data format comprising real data and metadata indicative of an attribute of the real data,
the second data format comprising the real data and the metadata in data units different from each other,
the third data format comprising the real data and the metadata in a single data unit,
the program causing the processor to perform operations comprising:
converting, in response to the input data being in the first data format or in the third data format, the data format of the input data to generate output data in the second data format.

8. The data processing apparatus according to claim 2 , wherein
the program further causes the processor to output the real data included in the output data to an ETL tool being an extract, transform, and load tool.

9. The data processing apparatus according to claim 8 , wherein
the program causes the processor to process the metadata in accordance with a process performed on the real data by the ETL tool.

10. The data processing apparatus according to claim 2 , wherein
the real data comprises sensing data generated by a sensor.

11. The data processing apparatus according to claim 3 , wherein
the real data comprises sensing data generated by a sensor.

12. The data processing apparatus according to claim 4 , wherein
the real data comprises sensing data generated by a sensor.
