Final answer:
When transactions are executing concurrently in an interleaved fashion, the order of execution of operations from all the various transactions is known as a scheduler. The scheduler is responsible for determining the order in which operations from different transactions are executed.
Step-by-step explanation:
When transactions are executing concurrently in an interleaved fashion, the order of execution of operations from all the various transactions is known as a scheduler. The scheduler is responsible for determining the order in which operations from different transactions are executed. It ensures that operations from different transactions do not interfere with each other, maintaining the consistency of the database.
For example, let's say two transactions T1 and T2 are executing concurrently. T1 performs an update operation and T2 performs a select operation. The scheduler may allow T1 to execute first, followed by T2. However, it can also choose to execute T2 first, depending on various factors such as transaction priorities, timestamps, or other scheduling algorithms.
