Think of a bank that has several database locations. Assume that persistent messaging is the sole method available for the databases to interact. This database is distributed, right? Why?

Assume that a database system is installed on a server with 3 core processors. You want your query to run on multiple processors so that each processor accesses in parallel a subset of the database. Or, you might set up your system in a way that partitions your query so that each part of the same query runs on a different processor. Explain, with an example, how a query might be broken apart so that each parallel processor handles a subset of the query

Imagine for a minute that a financial institution's database is being safeguarded by the snapshot isolation database technique.Do you offer a concrete example of how a nonserializable execution may be detrimental to a bank? If so, please distribute it.

Consider the database system of a bank that employs snapshot isolation. Describe a nonserializable execution that would pose a challenge for the bank.
