What is the primary function of the EMIs in message handling?

The primary function of the EMIs (External Message Interfaces) in message handling is to transform messages. This transformation process is crucial in ensuring that messages are formatted correctly, and properly encoded, and that they meet the requirements of the receiving system or application. This involves converting the message from one format to another or modifying the message content so that it is compliant with the specifications needed by the end-point systems.

In many messaging systems, transformation can include mapping data fields from the source to the target schema, enriching messages with additional data, or converting data types to fit business rules. This capability allows for seamless interoperability between different systems, ensuring that data can be shared and utilized effectively across diverse platforms.

The role of transforming messages is fundamental in environments where various systems need to communicate and where data formats may differ. This ensures that the integrity and structure of the data are maintained during transmission, allowing the recipient to accurately interpret the information.

While temporary storage of messages or deleting invalid messages may be parts of the overall messaging process, they are not the main focus of what EMIs do. The emphasis is squarely on the transformation aspect, as it directly impacts how data is handled and utilized in business processes.
