Abstract
A data retrieval system for a relational database, for retrieving a relational table in a relational database having parts separately identifiable within the system. A link data file stores link data which include parts descriptors that describe command names assigned to parts located at table item positions of the relational table, attribute descriptors which which describe command names of parts arranged in a row of the relational table corresponding to the command names described by the parts descriptors, and mode descriptors which describe command names of parts arranged in a column of the relational table corresponding to the command names described by the parts descriptors. An actual data file is provided for storing actual data related to the command names of the parts which form the relational table. A link process responds to requests for retrieval from the relational table. The link process obtains a command name corresponding to a retrieval request by referring to the link data file and then obtains the actual data described by the command name, from the actual data file.
