摘要

The method involves generating a function corresponding to an archive attribute, and generating a sub-structure of a relational database corresponding to a transaction associated to the function, within the relational database. A description of the sub-structure is generated. The description is sent under the form of a meta-document at a level of storage center. A new function is generated corresponding to the transaction.
