Stock Control Database

P: 5
Hello all,
I'am currently working on a stock control database of a small business.The business deals with buying products from suppliers and store it in the shrowroom. Then these products are sold to customers.

I have made the database so that it will calculate the product quantity level after sales and purchases and also product a reorder report.

The attachment shows the table design of my databae.
Can someone check my relationships if it is correct??

I need help for calculating the product quantity level.

Shall I use queries for that...that is one delete or update query that will decrease the quantity in the tblProduct upon Order( Sales/Customer Order). Also an append query for adding to the quantity in the tblProduct upon purchase Order

Thanks in advance.

Here is SQL code for tblProducts that may help you.
Expand|Select|Wrap|Line Numbers
  1. SELECT tblProducts.ProductID, tblProducts.ProductName, Sum(tblProducts.Inventory) AS StockLevel, Nz([ReOrderLevel],0-Nz([StockLevel],0)) AS ReStockAmnt, tblProducts.ReorderLevel
  2. FROM tblProducts
  3. GROUP BY tblProducts.ProductID, tblProducts.ProductName, tblProducts.ReorderLevel;
