File-Based Exchange
File-Based Exchange is a data integration approach where systems share information by reading from and writing to files in a common format, such as CSV, XML, JSON, or proprietary formats, stored in shared directories or cloud storage. It enables interoperability between disparate applications, often in batch processing scenarios, without requiring direct API connections or real-time communication. This method is commonly used for legacy system integration, data migration, and ETL (Extract, Transform, Load) processes.
Developers should learn and use File-Based Exchange when dealing with systems that lack modern APIs, require scheduled data transfers, or need to handle large volumes of data in bulk, such as in financial reporting, inventory updates, or healthcare data sharing. It is particularly useful in environments with network constraints, as it allows for offline data preparation and reduces dependency on continuous connectivity, making it a cost-effective solution for integrating older or heterogeneous systems.
