I have one parent table (table_p) with 3 child tables (table_ch1, table_ch2 and table_ch3). Each record of the parent table can be associated with 1 and only 1 child table records. This means that:
* Some records of the table_p will link to records of table_ch1
* Some records of the table_p will link to records of table_ch2
* Some records of the table_p will link to records of table_ch3
At first look, this does not make very much sense to me. I thought about considering 3 parent tables, one for each child table. However, the 3 parent tables would have the same exact structure and I would like to know if there is a workaround for this issue.
