Question

Describe, in your own words, the most common concurrent transaction execution problems. Explain thoroughly how concurrency control can be used to avoid each of these problems. Give specific examples where warranted.

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:
Tablename: PRODUCT
Tablename: PART
