Concept explainers

Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

Question

Another action may be triggered by the execution of a trigger. There is often a
limit on how deep nesting may go in database systems. Why could they impose
such a restriction?

In a database for an airline, "snapshot isolation" should be considered. Is a strategy that does not permit serialization a realistic alternative if airlines can enhance their overall performance?
Let's say there are two students interested in enrolling in a class but there is only room for one of them there. What factors prohibit both students from being assigned to the last open seat in the database system?
What's the difference between implicit and explicit locking in multiple-granularity locking?
Implementations of database systems often employ strict two-phase locking. Why is this technique so well-liked and regarded?
Many database system implementations strictly adhere to a two-phase locking paradigm. Weirdly, a lot of people seem to like and support this protocol.
Assume that a database does not enforce the requirement of maintaining referential integrity. Is it likely that any errors will occur?
Consider the term "snapshot isolation" as an example for a database used by an airline. Is the selection of a strategy that does not lend itself to serialization suitable in the event that airlines are able to improve their overall performance?
What is the distinction between optimistic and pessimistic locking?
In a database for an airline, "snapshot isolation" should be considered. Is a strategy that does not permit serialization a realistic alternative if airlines can enhance their overall performance?
What are the effects of an attack on a database's referential integrity? What kinds of mistakes could happen?
Consider the following scenario: there is only room for one student in the class that two students are trying to enroll in. What aspect of the database system makes it impossible for both students to claim the last open seat?
Consider a database for an airline that uses "snapshot isolation" for the sake of this demonstration. It is possible that the Airline will agree to a non-serializable execution if doing so will improve performance as a whole.
