Abstract: A storage unit stores therein information for specifying a cell contained in a file in a table format and attribute information on the file in an associated manner. When first information is stored in the storage unit in association with attribute information on a first file in a table format and second information is stored in the storage unit in association with attribute information on a second file in a table format, whether there is a relevance between the first file and the second file is determined by comparing the first information and the second information by referring to the storage unit.

Abstract: A non-transitory computer-readable recording medium stores a data management program that causes a computer to execute a process. The computer is configured to store data, which is a development deliverable of a product, in one of folders included in a storage folder group having a hierarchal structure. The process includes referring to a storage unit storing a plurality of items constituting an ISO (International Organization for Standardization) specification defining a development process of the product; outputting one or more items as options among the plurality of items constituting the ISO specification defining the development process of the product, when applying an attribute to the one of the folders included in the storage folder group; and implementing control to store the attribute corresponding to a selected item among the one or more items that have been output in association with the one of the folders.

Abstract: A storage unit stores therein an association relationship between information for specifying a first portion of a file in a first table format and information for specifying a second portion of a file in a second table format. The control unit extracts, upon receiving a search request for an area to be influenced by the first portion, the information for specifying the second portion associated with the information for specifying the first portion by referring to the storage unit, and outputs the information for specifying the second portion and information for specifying the file in the second table format containing the second portion, as a reply to the search request.
