Flat File Integration is a way of transmitting data between two separate systems in a flat, or unstructured, file format. In this type of integration, each record (or block of information) is transmitted separately as a string of characters without any structure. This makes Flat File Integration ideal for use when transferring data between two unrelated systems with different data formats and definitions. With Flat File Integration, businesses are able to quickly and smoothly exchange data without worrying about costly translations or conversions.
