PPROBLEM TO BE SOLVED: To efficiently perform reference access authority check processing on retrieval data. PSOLUTION: In the data retrieval device, a reference access authority range check part 012 registers a host node ID having reference access authority information matched with an input user ID in a referable host node ID list 132 in reference to a host node list 122. An attribute/ID collective retrieval part 013 retrieves data IDs having attribute information matched with a retrieval condition in reference to a data information list 121. At that time, the retrieval part 013 checks on whether a host node ID corresponding to the matched data ID exists in the referable host node ID list 132, and also checks on whether inheritance corresponding to the matched data ID exists. The retrieval part 013 outputs a data ID which is "matched with the retrieval condition", "the host node ID thereof exists in the referable host node ID list 132", and "has inheritance" as a retrieval result.
