Message Translator

Summary

A Message Translator is a component that translates a message from one format to another. It's used to connect systems that use different data formats.

What it is

Different applications often use different data formats. For example, one system might use XML, while another uses JSON. To make them communicate, you need to translate messages from one format to the other. This is what the Message Translator pattern does.

A Message Translator is a component that sits between two applications. It receives a message from one application, transforms its structure and format into what the other application expects, and then sends the translated message on its way.

This pattern is essential for integrating legacy systems or third-party applications that you can't modify. It allows you to decouple your systems, as the sender doesn't need to know about the receiver's data format, and vice versa. The translation logic is encapsulated in a dedicated component, making the integration easier to manage and maintain.
