A method of transferring batches of data to a target database includes receiving ordered rows of data and loading the ordered rows into batch tables. Each batch table being either a parent table, a child table or a no dependency table. The parent batch tables and no dependency batch tables are entered into a ready queue and the child batch tables are entered into a into a waiting pool. Any batch table in the ready queue may be transferred to the database using one or more processors. Any child batch table is moved to the ready queue if no corresponding parent table is in the ready queue. A dependency count of a child table is maintained and decremented if a parent table is imported to a database. In one embodiment, the corresponding child table in the waiting pool is transferred to the ready queue if the dependency count is zero.
