Q271. Can you explain spring boot project Architecture?

Ans. The architecture of a Spring Boot project can be divided into three layers:

Presentation Layer:
This layer is responsible for handling user requests and generating responses. It includes the user interface, which can be a web UI or a RESTful API. Spring Boot provides various options to develop web applications, such as Spring MVC, Thymeleaf, and others.

Service Layer:
This layer contains the business logic of the application. It is responsible for processing the user requests and generating responses. The Service Layer interacts with the Data Access Layer to fetch and store data.

Data Access Layer:
This layer is responsible for interacting with the database or any other external data source. It includes the database model, repositories, and data access objects. Spring Boot provides support for various data access technologies, such as JPA, JDBC, and Spring Data JPA.

Q275. Explain Hibernate caching mechanism

Hibernate

Ans. Every fresh session having its own cache memory, Caching is a mechanism for storing the loaded objects into cache memory. The advantage of cache mechanism is, whenever again we want to load the same object from the database then instead of hitting the database once again, it loads from the local cache memory only, so that the no. of round trips between an application and a database server got decreased. It means caching mechanism increases the performance of the application.

In hibernate we have two levels of caching

First Level Cache [ or ] Session Cache
Second Level Cache [ or ] Session Factory Cache [ or ] JVM Level Cache
