A search apparatus includes: an array index storage in which an array index having attribute position information for specifying a position at which an attribute value is located is stored for each of one or more records out of records and for each of one or more attributes of each record; a condition accepting unit that accepts a search condition including an attribute identifier corresponding to an attribute value; a search unit that retrieves attribute position information corresponding to the attribute identifier included in the search condition, from the array index, and retrieves an attribute value corresponding to the attribute identifier included in the search condition, using the attribute position information, from a data source storage in which a data source including two or more records having two or more attribute values is stored; and a result output unit that outputs a search result including the attribute value.

Search apparatus, search method, and storage medium

A data retrieval apparatus includes a processor, and a memory. The memory stores a virtual database that analyzes a retrieval request input from a user terminal to generate a retrieval instruction, executes the generated retrieval instruction in the database to acquire two or more retrieved data, and integrates the acquired two or more retrieved data to prepare a retrieval result responding to the retrieval request.

Data retrieval apparatus, program and recording medium

A data retrieval apparatus includes a processor, a memory and a business intelligence circuit. The memory stores a data dictionary including presentation structure definition information for assisting 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. The business intelligence circuit assists input of the user terminal according to a presentation structure defined in the data dictionary to issue a retrieval request described according to the presentation structure, and outputs a retrieval result based on the retrieval request, the retrieval result being obtained from the databases, to the user terminal. The data retrieval apparatus associates retrieval results prepared in response to different retrieval requests with each other according to the retrieval request definition information.

To provide a data retrieval tool for analyzing data including inconsistency that is difficult to cope with in a single cube. This data retrieval tool is characterized in that data respectively obtained from a plurality of databases are integrated to prepare a plurality of retrieval results on the basis of different retrieval requests and a plurality of reports obtained from the plurality of retrieval results are automatically associated and manipulated, by integrating a function of a virtual database unit with a function of a business intelligence unit by means of integral software and controlling the integrated result with a single data dictionary capable of managing the associations between the different retrieval requests.
