Spring

Spring Framework is an open-source framework for building Java applications. It provides a comprehensive programming and configuration model that simplifies the development of Java applications, especially in complex enterprise environments.

Key Features:
-Inversion of Control (IoC): Spring manages object creation and dependencies using Dependency Injection (DI), making it easier to manage and test application components.
- Aspect-Oriented Programming (AOP): Allows the separation of cross-cutting concerns (like logging, transactions, and security) from the business logic.
- Spring MVC: A web framework based on the Model-View-Controller pattern, used for building web applications and RESTful APIs.
- Transaction Management: Simplifies database transactions and integrates easily with various database technologies.
- Spring Boot: A sub-project of Spring that makes it easier to set up and run Spring applications by providing sensible defaults and auto-configuration.

Spring is widely used for building scalable, secure, and maintainable applications, ranging from simple web apps to large-scale enterprise systems.
