SQL & PL/SQL :: Insert Into Target Table And Delete From Source

We have a requirement to archive and purge the tables dynamically based on the control table input. For that we have to design a control table to gather the necessary information and passed to generate the queries.

I have designed the table as below.But in this case I am not able to handle the parent and child relation ship.

Suppose one table needs to be archived and purged and that table is parent table and it is having 2 child tables, so first required data will be inserted into target table and delete from source parent and child tables. so before deleting from parent we have to delete data from all 2 child tables.

Suppose one table needs to be purged and that table is parent table and it is having 5 child tables, so before deleting from parent we have to delete data from all 5 child tables.

To handle this scenario how can I design my control table.

For archive and purge the query like this.
INSERT INTO towner_name.ttable_name
(SELECT * FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30));
DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);

for purge the quey is like this.
DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);

This is my control table and I have 300 tables list to archive and purge.

CID SOWNER_NAME STABLE_NAME TOWNER_NAME TTABLE_NAME CONDITION_COLUMN PERIOD UNIT TYPE
1 wedb_au OFFER_HEADER wedb_au OFFER_HEADER LAST_DATE 30 D A
1 wedb_sa OFFER_CUSTOMER wedb_sa OFFER_CUSTOMER LAST_DATE 60 D A
1 wedb_au OFFER_SERVICE LAST_DATE 1 Y P
1 wedb_us OFFER_CUSTOMER LAST_DATE 90 D P
1 wedb_cn OFFER_CARDS UPDATE_DT 2 Y P
2 wedb_au ORDER_HEAD wedb_au ORDER_HEAD LAST_DATE 120 D A
2 wedb_us ORDER_CUSTOMER wedb_us ORDER_CUSTOMER LAST_DATE 150 D A
2 wedb_sa ORDER_HEAD wedb_sa ORDER_HEAD CREATION_DT 1 Y A
3 wedb_us DELIVERY_HEAD wedb_us DELIVERY_HEAD UPDATE_DT 50 D A
3 wedb_au DELIVERY_CARDS wedb_au DELIVERY_CARDS UPDATE_DT 200 D A
3 wedb_au DELIVERY_SERVICE wedb_au DELIVERY_SERVICE LAST_DT 100 D A

WHERE TYPE=P means insert and delete
TYPE=A means only delete

wedb_au.OFFER_HEADER is Parent Table.
child tables for wedb_au.OFFER_HEADER are wedb_au.OFFER_SERVICE,wedb_au.OFFER_BODY,wedb_au.OFFER_EMAIL,OFFER_TAX.
wedb_au.OFFER_SERVICE is child table and parent for this table is wedb_au.OFFER_HEADER
wedb_sa.OFFER_CUSTOMER Stand alone table no relationship
wedb_us.OFFER_CUSTOMER Stand alone table no relationship
