Web Service

Definition

A web service is a standardized way of integrating web-based applications using open standards over an internet protocol backbone.

Detailed Description

Web services enable communication and data exchange between software systems over the internet. They use standardized XML messaging systems such as SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) to facilitate this integration. In the context of ERP systems, web services allow different modules to communicate seamlessly, enabling the integration of various business processes across disparate systems. By leveraging web services, organizations can ensure that their ERP systems effectively interoperate with other enterprise applications, thereby extending functionalities, enhancing interoperability, and improving flexibility.

Key Features

• Decoupled architecture for flexibility
• Platform-independent communication
• Scalability for integration with multiple systems
• Standardized protocol usage (SOAP, REST)
• Supports multiple data formats (XML, JSON)

Examples

import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloWorldController { @GetMapping("/hello") public String sayHello() { return "Hello, World!"; }}
