An overview of various dependencies used commonly across various projects in the form of categories.

Server

Database

H2

• H2 Database offers both in-memory and file-based database options. Integrating H2 database into Maven project involves two main scenarios i.e. using it for persistence in application or for integration testing. Dependency scope as test ensures the dependency is only available during tests and not included in the final packaged application.

H2 Database Dependency

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.199</version>
    <scope>test</scope>
</dependency>

H2 database specific properties can be defined in application.yaml file like below.

spring:
  datasource:
    url: jdbc:h2:mem:testdb
    username: sa
    password:
    driver-class-name: org.h2.Driver

• In-memory: Use jdbc:h2:mem:your_database_name for a private in-memory database

• File-based: Use jdbc:h2:~/your_database_name or jdbc:h2:file:your_database_name to store data in a file on your local system.

Oracle

• Oracle Driver

Oracle JDBC driver for Java allows Java applications to connect to Oracle database. It's commonly used when developing Java applications that need to interact with Oracle database.

Utility

• Lombok

Lombok is a Java library that helps reduce boilerplate code by providing annotations to generate getter, setter, constructor, and other utility methods during compilation. This can lead to cleaner and more concise code.

It provides annotations which help reduce boilerplate code for getters, setters, equals, hashCode, , toString, constructors, builders, loggers, checked exceptions handling with @SneakyThrows, data validation with @NonNull to enforce non-null fields etc.
