Question
Chapter 6, Problem 6.23RQ
Program Plan Intro
Consistency:
A transaction which proceeds to the valid state of data or if any failure occurs, it returns all the data to its state at the point where the transaction begins.
- It stands for correctness and ensures that any transaction will carry the
database from one valid to state to another valid state. - Application programmer is responsible for maintaining the consistency.
