Sure. Join your various tables and group the result set by product, counting
the various measurement along the way.
E.g.
select product.product_id,
sum( inventory.??? ) as inventory,
sum( sale.??? ) as sale,
sum( receive.??? ) as receive,
sum( balance.??? ) as balance
from product
left join inventory
on inventory.product_id = product.product_id
left join sale
on sale.product_id = product.product_id
left join receive
on receive.product_id = product.product_id
left join balance
on balance.product_id = product.product_id
group by product.product_id
order by product.product_id
