Methods and associated structures for improving streaming database translation by use of an auxiliary database to store supplemental information derived as a by-product of the importation process and to then update the target database of the importation process using the supplemental information so generated. The supplemental information may include information such as supplemental attributes that define additional joins to be created in the target database following importation. In particular aspects hereof applicable to GIS database applications, supplemental geometric information may be derived from the source database during the importation process and stored in the auxiliary database. Following completion of the importation, the target database may be updated to add the geometric information from the auxiliary database to the newly imported objects in the target database.
