Serializability: Serializability of the transaction specifies a list of transactions in a schedule (like read, write or commit) that is performed in a manner that it looks like transactions execute in a specific serial order. In a given schedule, the individual transaction executes consecutively in isolation (no interference by other transactions). The types of serializability in the database are conflict serializability and view serializability.

Serializability:

Serializability of the transaction specifies a list of transactions in a schedule (like read, write or commit) that is performed in a manner that it looks like transactions execute in a specific serial order.

In a given schedule, the individual transaction executes consecutively in isolation (no interference by other transactions).

The types of serializability in the database are conflict serializability and view serializability.

Explanation of Solution

b.

Ensuring global serializability:

The system is guaranteed to have the local serializability, any cycle occurring in the system-wide precedence graph should include two or more different sites and two unique global transactions.

The ticket scheme guarantees that whenever two global transactions will access data-items at a site, the conflict occurs on that data item (or ticket) at that site...
