What is the role of transactions in TinyDB, and how are they implemented?
Transactions in TinyDB ensure data consistency by providing atomicity and isolation.
* Atomicity : All operations within a transaction are treated as a single unit of work that either succeeds or fails as a whole.
* Isolation : Transactions are isolated from each other, so changes made in one transaction are not visible to other transactions until they are committed.
Transactions in TinyDB are implemented using the transaction() context manager, which wraps a block of code in a transaction.
