Which statement accurately describes the Message Handler?

The correct statement regarding the Message Handler is that it follows the instruction defined in the incoming message definition. The role of the Message Handler is to interpret the details embedded within incoming messages and execute the necessary actions according to those instructions. This can include processing commands, updating systems, or triggering workflows based on the content and structure of the incoming message.

This functionality is essential for maintaining effective communication within systems, ensuring that the commands and data conveyed in messages are accurately understood and acted upon. By adhering to the definitions provided in the incoming messages, the Message Handler plays a crucial role in integrating various components of the system and facilitating smooth operations that involve message exchanges.

In contrast, other options either misrepresent the primary function of the Message Handler or limit its scope. For example, while it may execute database-related tasks, saying it does so rapidly does not reflect its core capability related to handling message instructions. It is also not merely a type of message parser; it encompasses more complex interactions based on message content. Lastly, the notion that it only processes outgoing messages overlooks its fundamental role in responding to incoming messages and following their defined instructions.
