Nowadays, most of the systems are transforming data in the form of XML, JSON, etc, but legacy applications/systems are still using Flat files to exchange data between the systems.
A Flat File can contain multiple lines of data with each line containing different line identifiers. Each line can have many fields of data, separated by a special character like Comma, Pipe, and Fixed width. https://goo.gl/PtHoHL #DataIntegration #ML
