Question

Write the transaction log using Table 10.1 from the textbook as your guide. Assume that product ‘ABCD’ has a PROD_QOH = 1,214 at the start of the transaction and that the transaction is representing the addition of 1 new product. Also assume that PART components “AAAA”, “BBBB”, “CCCC” and “DDDD” have a PROD_QOH equal to 547, 108, 249, and 89 respectively.

ACTION ITEMS
Suppose you are a manufacturer of product ABCD, which is composed of parts AAAA, BBBB,
CCCC and DDDD. Each time a new product is created, it must be added to the product
inventory, using the PROD_QOH in a table named PRODUCT. And each time the product
ABCD is created, the parts inventory, using PART_QOH in a table named PART, must be
reduced by one each for parts AAAA, BBBB, CCCC and DDDD. The sample database contents
are shown below for these items:
