In one embodiment, a data processing system includes a first database 304 maintained by a first party (such as a customer); a second database 324, 328 maintained by a second party (such as a vendor) different from the first party; a work queue 316 to specify data to be added to the second database; an extract, transform and load module 308 to write data from the first database to the work queue; and a data import module operable 320 to import data from the work queue to the second database. In the system, the first party is not privileged to write the data directly to the second database but is privileged to write the data to the work queue. The import module transforms the data written to the work queue to a form semantically compatible with the second database.
