A concurrent schedule in DBMS refers to multiple transactions running concurrently without interfering with each other. This allows for improved performance and efficiency in handling multiple operations simultaneously. However, it requires careful management to ensure data consistency and avoid conflicts such as race conditions.

What is View Serializable in DBMS?
View Serializable is a correctness criterion in database management systems that ensures that the final result of executing concurrent transactions is the same as if they were executed one after the other. This property helps maintain data consistency and ensures that the database remains in a consistent state despite concurrent transaction execution. Transactions are said to be view serializable if their interleaved execution produces the same results as if they were executed sequentially.
What is data isolation in dbms explain with example?
Data isolation in DBMS refers to the concept of keeping data from interfering with each other in concurrent transactions. This means that changes made by one transaction are not visible to other transactions until they are committed. For example, if two users are updating the same database record simultaneously, data isolation ensures that one user's changes are not visible to the other user until they have both finished their transactions and committed the changes.
What is the fullform of DBMS?
The full form of DBMS is Database Management System.
What is the difference between flat file and DBMS?
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.
How does DBMS handle concurrent updates in MySQL?
MySQL is an RDBMS.
Serial schedule differs serializable schedule in dbms?
Serial schedules are the schedules during which all statements in a transaction are executed consecutively. Serializable schedule is a schedule that is equivalent to a serial schedule
WHAT TASKS does dbms do?
A Database Management System or DBMS provides the interface between users and a database. Some of its tasks include: data integrity, security, recovery of data, support concurrent updates and update data.

What is scheduling in dbms?
schedule is an interleaving of action from a set of transactions where the action of any transaction is in the original order.
What is concurrent schedule?
A complex reinforcement procedure in which the participant can choose any one of two or more simple reinforcement schedules that are available simultaneously. Concurrent schedules allow for the measurement of direct choice between simple schedule alternatives.

Difference between serial and non-serial schedule?
Serial ScheduleNon-Serial ScheduleA serial schedule is a sequence of operation by a set of concurrent transaction that preserves the order of operations in each of the individual transactions.A non-serial schedule is a schedule where the operations of a group of concurrent transactions are interleaved.Transactions are performed in serial order.Transactions are performed in non-serial order, but result should be same as serial.No interference between transactionsConcurrency problem can arise here.It does not matter which transaction is executed first, as long as every transaction is executed in its entirely from the beginning to end.The problem we have seen earlier lost update, uncommitted data, inconsistent analysis is arise if scheduling is not proper.A serial schedule gives the benefits of concurrent execution without any problemIn this schedule there is no any benefit of concurrent execution.Serial schedule that does interleaved the actions of different transactions.Where non-serial schedule has no only fix actions of any transaction.EXAMPLE:If some transaction T is long, the other transaction must wait for T to complete all its operations.EXAMPLE:In this schedule the execution of other transaction goes on without waiting the completion of T.If we consider transaction to be independent serial schedule is correct based on (property ACID) above assumption is valid.The objective behind serializability is to find the non-serial schedule that allows transactions to execute concurrently without interfering one another.
