Patent ID: 8412670

Claim:
A non-transitory computer-readable recording medium storing an information integration program, the information integration program causing a computer to transform data extracted from an information source and load the transformed data onto a storage destination, the information integration program causing the computer to perform operations comprising: detecting a schema modification of the information source by comparing first schema information acquired from the information source with second schema information acquired from the information source prior to modifying the first schema information; searching a correspondence table storage unit for an attribute value of an item related to the schema modification, the correspondence table storage unit storing the attribute value included in schema information and item information in a data model, with the attribute value mapped to the item information; generating a post-modified data model by correcting a pre-modified data model stored on a metadata information storage unit 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, the metadata information storage unit storing the pre-modified data model corresponding to the second schema information; 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, the post-modified integration logic transforming the post-modified data model stored on the storage device into a data model corresponding to the storage destination.
