How to design Parent and Child relationship tables using Talend.

I have to establish the relationship between parent and child tables using Talend.
I tried to design but it is not working as expected.
Please suggest the best way to do this.
I am using Oracle_Sequence for my key column in the the parent table.

Could you explain your design issue a little more? Are you trying to use a sequence to load parent and child tables?

Hi Willim,
Thaks for replying to my post..
I have a Act_id in parent table which uses oracle sequence and same Id i need to insert into two child tables..
While inserting it is working as expected.But for update operation,the key value is getting changed.
Both in parent and child tables..
If i change the key to different column ..It is inserting another record in child table.If i process the same file for one more time..
The way i have designed is..I created a tMap and from there i mapped to tables..I used tOracleInput for getting the sequence id value and mapped to the parent and child tables..
If you can provide the steps to design the workflow that would be really great..I am new to talend and trying to learn step by step..
i have selected the Table Action as "Update or Insert" for both the tables..
I have attached my design as an image to this post..Let me know if you need any more details.

Looks like you're merging data from your XML with data from your Oracle table that includes a sequence number... Can you share a screenshot of your tMap?
