In OpenERP/Odoo, we have one2many and many2many datatype field. For add, update, delete we have some trick to link with record, which are listed below.
1. (0, 0, { values }) link to a new record that needs to be created with the given values dictionary
2. (1, ID, { values }) update the linked record with id = ID (write *values* on it)
3. (2, ID) remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
4. (3, ID) cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
5. (4, ID) link to existing record with id = ID (adds a relationship)
6. (5) unlink all (like using (3,ID) for all linked records)
7. (6, 0, [IDs]) replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)
