An apparatus acquires a first input-table, based on target table information, and acquires a script for generating a first output-table from the first input-table, and a constraint condition between columns included in the first input-table and the first output-table. The apparatus converts the first input-table into a second input-table such that the second input-table obtained by converting a column structure of the first input-table and a second output-table to be obtained by converting a column structure of the target table comply with the constraint condition, and generates assignment information indicating a correspondence relationship between columns to be included in the second output-table and the target table. The apparatus generates the second output-table from the script and the second input-table, and converts the second output-table into the target table, based on the assignment information.

A method includes acquiring one or a plurality of first tables including a first data group regarding a first item, acquiring a second table corresponding to a result of executing a program with the one or the plurality of first tables set as an input, the second table including a second item and a second data group, generating, when a first name of the first item and a second name of the second item have a relationship in which the first name partially matches the second name, first information indicating the relationship between the first name and the second name while defining parts that partially match, registering the first information in a memory as metadata for the program, the metadata indicating a relationship between the one or the plurality of first tables set as the input and the second table set as an output.

Metadata registration method and device

A data processing method includes steps of; allowing establishment of a first flag or a second flag for each of a plurality of items where corresponding values are inputted sequentially; upon detecting that a value associated with an item where the first flag is established in an Nth place is inputted and that a value associated with an item where the second flag is established in an Mth place (M is equal to or larger than N) is inputted, executing a predetermined processing to values in a range from the value that is inputted by associating with the item where the first flag is established in the Nth place to the value that is inputted by associating with the item where the second flag is established in the Mth place; and executing a processing of outputting a processed result in order from the item in the Nth place.

A retrieval device according to the present embodiment associates one tag key with one node and removes a node not having a tag key when a trie tree generating unit generates a trie tree. Moreover, because a tag key having a low priority is registered in a node close to a root node when the trie tree generating unit registers tag keys in the nodes of the trie tree, the retrieval device can narrow down a node region that is a comparison target when a trie tree searching unit performs a retrieval process.
