Abstract: An information integration method performed by a computer that transforms data extracted from an information source and loads the transformed data onto a storage destination, the information integration method includes detecting a schema modification of the information source by comparing first schema information with second schema information; searching a correspondence table storage unit for an attribute value of an item related to the schema modification; generating a post-modified data model by correcting a pre-modified data model using the item information corresponding to the attribute value of the item related to the schema modification when the attribute value of the item related to the schema modification is hit in the correspondence table storage unit, and storing the post-modified data model on a storage device; and generating a post-modified integration logic and storing the post-modified integration logic on the metadata information storage unit.
