DATA LINK ASSISTANCE DEVICE AND DATA LINK ASSISTANCE METHOD

WIPO Patent Application WO/2014/192116

A1

Provided is a data link assistance device for efficiently detecting in a data link which table has a reference relation with a link destination table. A data link assistance device specifies a primary key first column and a second column which is not a primary key for each respective table other than a link destination table, from a plurality of columns included in the tables. The data link assistance device extracts a table from the tables other than the link destination table wherein a third column is present in the link destination table which is similar to the first column and a fourth column is present in the link destination table which is similar to the second column. The data link assistance device outputs recommendation information which recommends using the combination of the link destination table and the extracted table in the data link.
