How do you start and finish a transaction in DBMS?
any change in database is called transaction.
Transactions' Importance:Users can submit transaction and can think of each transaction as executing by itself.A transaction might commit after completing all its actions, or it could abort(or be aborted by the DBMS) after executing some actions.

schedule is an interleaving of action from a set of transactions where the action of any transaction is in the original order.
DBMS (Database Management Systems) typically overcome TFBS (Transaction Failure Before System) by using transaction management techniques such as ACID properties (Atomicity, Consistency, Isolation, Durability). These ensure that transactions are either fully completed or reverted to their original state in case of failure, maintaining data integrity. Additionally, DBMS often implement logging and recovery mechanisms to help recover the database state in case of unexpected failures.
Durability is the part of recovery system ,it has response to recover the failure data,it also comes under transaction managment
A "start transaction" is set to be the system's first screen displayed once you log in to GCSS-Army. Setting up a start transaction is ________
Primarily it's based on rules about when changes to data are posted in a transaction and read by other users, which are part of the record-locking features of the DBMS. Some DBMS's manage this with undo and redo logs, which support snapshotting the data before the updates were started, so that other users can access the records before the update transaction was started.
An accounting transaction is the exchange of request/response messages to perform accounting. Accounting can be performed in the form of accounting transactions that report on resource usage by a session. Accounting transaction can occur during a session if accounting or charging indications are needed [pol based acct] or only at the start and the end of the session. http://209.85.175.104/search?q=cache:EcDJEY4QjJAJ:www.aaaarch.org/doc09/session_id-29nov2000.doc+%22accounting+transaction+is+the%22&hl=id&ct=clnk&cd=2&gl=id A transaction is 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 includes the reading and writing of database.
Yes! The master file of a DBMS is a data file containing relatively permanent records that are generally updated periodically. The transaction file is a temporary file that holds all changes to be made to the master file, such as additions, deletions, and revisions. A transaction file has to be sorted before it is used to update the master file. By the way, I didn´t get your question, but I hope I helped =D
