They are used to protect user data from system failures in DBMS.
Transactions contain a finite number of steps and executing the same program multiple times generates multiple transactions.
Transactions can be implemented using SQL queries and servers.
ACID properties are desirable for a transaction to be performed in DBMS.
Transactions have different states such as active, partially committed, and committed.
Serializability is important to maintain database consistency.
Schedules are used to line up transactions and execute them one by one.
