An analysis is performed based on the nucleotide sequences. An in situ hybridization experiment is conducted, and expression statuses of genes that correspond to the genetic clones in a specific cell, tissue or organ are examined.

Abstract: A structured data described in a structured description language and a schema data that defines a structure of the structured data, are acquired from an external database. The structured data and the schema data are converted based on schema format conversion instruction information. The structured data and the schema data converted are registered in a database. A tool program and schema resource definition information are registered in a corresponding manner. When a tool program is started, the structured data and the schema data registered in the database are converted into a format suitable for the tool program, based on the schema resource definition information corresponding to the tool program. The structured data and the schema data after this conversion are input to the tool program.
