Infix: The typical mathematical form of expression that we encounter generally is known as infix notation. In infix form, an operator is written in between two operands. For example: An expression in the form of A * ( B + C ) / D is in infix form. Prefix: In prefix expression, an operRead more
Infix: The typical mathematical form of expression that we encounter generally is known as infix notation. In infix form, an operator is written in between two operands.
For example:
An expression in the form of A * ( B + C ) / D is in infix form.
Prefix: In prefix expression, an operator is written before its operands. This notation is also known as “Polish notation”.
For example, The above expression can be written in the prefix form as / * A + B C D.
Postfix: In postfix expression, an operator is written after its operands. This notation is also known as “Reverse Polish notation”.
For example, The above expression can be written in the postfix form as A B C + * D

The deferred-modification technique ensures transaction atomicity by recording all database modifications in the log, but deferring all write operations of a transaction until the transaction partially commits (i.e., once the final action of the transaction has been executed).

The deferred-modification technique ensures transaction atomicity by recording all database modifications in the log, but deferring all write operations of a transaction until the transaction partially commits (i.e., once the final action of the transaction has been executed). Then the information in the logs is used to execute the deferred writes. If the system crashes or if the transaction aborts, then the information in the logs is ignored.
The immediate-update technique allows database modifications to be output to the database while the transaction is still in the active state. These modifications are called uncommitted modifications. In the event of a crash or transaction failure, the system must use the old-value field of the log records to restore the modified data items.
