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.

Let's imagine a database for an airline that uses "snapshot isolation" for this example. Airline could agree to a non-serializable execution if it results in better overall performance.
Consider a database that belongs to an airline and employs snapshot isolation for its database management system. Describe an instance in which a nonserializable execution takes place, but the airline is open to the possibility that it will be prepared to tolerate it in exchange for improved overall performance.
Consider a database system that leverages snapshot isolation for an airline. Describe a situation in which a nonserializable execution happens, but the airline is ready to tolerate it to improve overall performance.

The utilization of "snapshot isolation" can be employed as an illustrative example to elucidate the construction of a database for an airline. In the event that airlines are capable of enhancing their overall performance, could the acceptance of a non-serializable method be deemed appropriate?
There are a number of databases that employ snapshot isolation in their systems, such as an airline's, for example. The airline may be willing to accept a nonserializable execution in order to improve overall performance.
In this case, an aircraft database with "snapshot isolation" is used. What if non-serializable processing improves how well a flight works?

Let's look at an airline database to see how snapshot isolation is used in practice. The airline, for instance, could agree to a nonserializable execution if it means better long-term outcomes.
