Answer 1

Transaction schedules are noted in a tabular format, while transactions are noted by an identifier or name.

Step-by-step explanation:

In transaction schedule notation, each schedule is noted using a tabular format. A transaction schedule is a chronological order of transactions and their corresponding operations. It shows the order in which transactions are executed in a database system. Each operation is represented as a row in the table, with columns indicating the transaction identifier or name, the type of operation (e.g., read or write), and the data item involved.

On the other hand, each transaction is noted by an identifier or name. This identifier uniquely identifies the transaction and allows it to be differentiated from other transactions. The identifier can be used to track the progress of the transaction and ensure that it completes successfully.
