Assume for a moment that a bank employs a technique called snapshot isolation to guarantee the safety of its database. Can you provide an example of how the bank can have difficulties due to a non-serializable execution?

Take a database used by airlines and apply the concept of "snapshot isolation" to it. Is it acceptable for airlines to use a non-serializable method if they can boost their overall performance?

What is a stable database state, and how do you get one? There is no assurance that the database management system's representation of the transaction's underlying actual occurrence corresponds to its symbolic meaning. What consequences would such a restriction have? Give an example to illustrate what you mean. Does "serializable transactions" imply what it seems to mean?
