Question
Chapter 8, Problem 8.31RQ
Program Plan Intro
Distributed
- A database that can store and process the data in one or more system is called as distributed database.
- Distributed database can be available either partitioned and in a replicated manner.
Replicated database:
Replicated database is where multiple copies of the database are stored at different locations.
Partitioned database:
A Partitioned database is where individual chunks of the database contents are stored on different computers.

Isolation requires that each transaction sees a consistent database at all times and that an executing transaction cannot reveal its results to other concurrent transactions before its commitment. ANSWER If two concurrent transactions access a data item that is being updated by one of them, it is not possible to guarantee that the second will read the correct value. Dirty reads and nonrepeatable reads may occur when one transaction can see intermediate results of another transaction before it has been committed.. Given below are two concurrent transactions T1 and T2 whose balances of amount x (balx) were recorded at times t, between t₁ and tg. As shown in the table below: If these two transactions interfere with each other, fill in the table below by selecting from the drop down list the values of balance X (bal,) at specified times…arrow_forward
