US Patent 7890454 Method and system for data disaggregation

A method and system for migrating source data from a source database to a destination database based on energy efficiency and conservation. A migration server evaluates the source data for usage and requirements and defines data usage and requirement tags for the source data. The source data is disaggregated into one or more source data sets based on the data usage and requirement tags. The migration server then identifies candidate destinations for the source data, wherein each candidate destination has stored data identified with usage and requirement tags. The data migration server compares the first usage and requirement tags of the source data with the second usage and requirement tags of the stored data and identifies an optimal destination database based on the comparing step. The data migration server migrates the source data to the optimal destination database.
