Data retrieval apparatus, program and recording medium

A non-transitory computer-readable recording medium storing a program causing a computer to function as a data retrieval apparatus that retrieves data from two or more databases that return retrieved data in response to a retrieval instruction, the program causing the computer to function as:

• a data dictionary including
• presentation structure definition information for assisting an input of a user terminal to issue a retrieval request compliant with a retrieval requirement, and
• retrieval request definition information for managing relevance between different retrieval requests;
• and
• a business intelligence circuit that
• assists an input of the user terminal to issue a retrieval request described according to a presentation structure defined in the data dictionary, and
• outputs a retrieval result based on the retrieval result, the retrieval result being obtained from the two or more databases, to the user terminal,
• wherein the data retrieval apparatus associates a plurality of retrieval results prepared in response to the different retrieval requests with each other according to the retrieval request definition information.

A method of analyzing data using a retrieval apparatus that retrieves data from two or more databases that return retrieved data in response to a retrieval instruction, the method comprising:

• storing, in a memory of the retrieval apparatus, a data dictionary, the data dictionary including;
• presentation structure definition information for assisting an input of a user terminal to issue a retrieval request compliant with a retrieval requirement, and
• retrieval request definition information for managing relevance between different retrieval requests;
• and
• assisting, by the retrieval apparatus, an input of the user terminal to issue a retrieval request described according to a presentation structure defined in the data dictionary,
• obtaining, by the retrieval apparatus and from the databases, a retrieval result based on the retrieval request,
• outputting, by the retrieval apparatus and to the user terminal, the retrieval result based on the retrieval request, and
• associating, by the retrieval apparatus, a plurality of retrieval results prepared in response to different retrieval requests with each other according to the retrieval request definition information.
