Database and app orchestration in Spring Boot - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the role of Spring Boot in database and app orchestration?

Spring Boot simplifies app setup and orchestration by auto-configuring database connections, managing transactions, and integrating data access layers seamlessly.

What is a DataSource in Spring Boot?

A DataSource is a factory for connections to the physical database. Spring Boot auto-configures it to manage connection pooling and database access.

How does Spring Boot manage transactions in database orchestration?

Spring Boot uses the @Transactional annotation to handle transactions, ensuring that database operations complete fully or roll back on errors, keeping data consistent.

What is Spring Data JPA and how does it help in app orchestration?

Spring Data JPA provides easy integration with JPA-based databases, allowing developers to write less code for database operations and focus on business logic.

Explain the concept of connection pooling in Spring Boot database orchestration.

Connection pooling keeps a set of open database connections ready to use, improving app performance by reusing connections instead of opening new ones each time.

Which annotation in Spring Boot is used to manage database transactions?

A @Service

B @Autowired

C @Component

D @Transactional

The @Transactional annotation tells Spring Boot to manage transactions for the annotated method or class.

What does Spring Boot auto-configure to manage database connections?

A Service

B DataSource

C Controller

D Repository

Spring Boot auto-configures a DataSource to handle database connections and pooling.

Spring Data JPA helps developers by:

A Writing SQL queries manually

B Managing UI components

C Simplifying database operations with less code

D Handling HTTP requests

Spring Data JPA reduces boilerplate code for database operations, letting developers focus on business logic.

What is the main benefit of connection pooling?

A Reusing open connections to improve performance

B Slower database access

C Increasing database size

D Encrypting data

Connection pooling improves performance by reusing existing database connections instead of opening new ones.

In Spring Boot, which layer typically interacts directly with the database?

A Repository

B Service

C View

D Controller

The Repository layer handles direct database access in Spring Boot applications.

Describe how Spring Boot orchestrates database connections and transactions in a simple app.

Think about how Spring Boot sets up and manages database access without much manual setup.

Explain the advantages of using Spring Data JPA in app and database orchestration.

Consider how Spring Data JPA helps developers write less code for database tasks.
