CHAPTER 8 
Software Requirements Analysis Practice
administration of the personnel and group accounts, protect personal data, and 
monitor data access needs to be specified to ensure proper data security.
8.3.7 
Identify data storage transactions
The operational model should be analyzed to identify the requirements for each 
data storage and retrieval transaction. The rules for executing each transaction and 
the conditions that would necessitate rolling back the transaction should be iden-
tified. The selected DBMS should be reviewed to identify causes for transaction 
deadlock situations. During functional analysis, these potential deadlock situations 
should be further decomposed to identify how the software product will need to 
monitor each transaction to detect deadlocks and how these situations should be 
resolved by cancelling and rolling back the transaction, or the use of other preven-
tative measures that avert deadlock situations from occurring.
