Interface engines are software applications that provide a platform for connecting two or more disparate systems. They are used to enable communication between different systems and to ensure that data is exchanged in a consistent and reliable manner. Interface engines provide a bridge between different systems, allowing them to interact with each other without requiring any changes to the underlying systems. They are often used to facilitate data integration, system interoperability, and automated data exchange. Interface engines are also used to provide a secure, efficient, and reliable platform for exchanging data between different systems. By providing a secure and reliable platform for data exchange, interface engines can help to reduce the complexity of data integration and system interoperability. Additionally, interface engines can help to reduce the cost of data integration and system interoperability by providing a platform for automated data exchange.
