How DBMS can be interleaved?
A DBMS is typically shared among many users. Transactions from these users can be interleaved to improve the execution time of users’ queries. By interleav- ing queries, users do not have to wait for other user’s transactions to complete fully before their own transaction begins.
What is a transaction in DBMS?
1. Atransactionis an execution of a user program, and is seen by the DBMS as a series or list of actions. The actions that can be executed by a transaction include reads and writes of database objects, whereas actions in an ordinary program could involve user input, access to network devices, user interface drawing, etc. 2.
