Product_id (pk) Product_Catg_id(fk) Product_Sym_id(fk)

Product_name Product_name Product_name

Product_MRP Category_name Symptom_name

......................................................................

in my asp application if i delete product_name in product table it has to delete in Product_Categories and Product Symptoms also. Same thing for Update also.

The easiest way is to let SQL handle it: use Cascading Delete.
