File-Based Integration
File-based integration is an approach to system integration where data is exchanged between applications or systems using files as the medium. This typically involves one system writing data to a file in a shared location, and another system reading from that file to process the data. It is commonly implemented with formats like CSV, XML, JSON, or flat files, often using protocols such as FTP, SFTP, or shared network drives for file transfer.
Developers should learn file-based integration for scenarios where systems are loosely coupled, batch processing is acceptable, or real-time communication is not required, such as in legacy system integrations, data warehousing ETL processes, or when dealing with intermittent connectivity. It is particularly useful in environments with high latency, for large data transfers, or when integrating with systems that lack modern APIs, as it provides a simple, reliable, and platform-agnostic method for data exchange.
