Hello Welcome to Forums,
Repeating recursive means each group has itself one more group which is repeating node. If you want to submit the same structure of data to one table then you have to get the list of repeating section nodes. For each repeating section node you have to submit via code.
If you want to submit for same structure of repeating node data to different table then you have to submit by the position of the node you can submit to the database. For this you have to limit the number of tables which are repeated the same structure for each table.
