In relational databases, flat file is sometimes used as a synonym for a "relation." However, they are typically extremely limited as opposed to a database that structures its data. In this blog, we will discuss most widely used file format in Hadoop Parquet ecosystem. After the transmission is complete, the data is altered and saved in different forms. Coupa's Common Flat File templates are designed to import many records from a single file sent to Coupa, not designed to process a high volume of files containing a single record each. Apache Parquet is designed for efficient as well as performant flat columnar storage format of data compared to row based files like CSV or TSV files. All of the descriptions are included on this page, so it can be printed as a single document. Compared to a traditional approach where data is stored in row-oriented approach, parquet is more efficient in terms of storage and performance. A file layout is a definition that represents the data structure of a flat (text) file to be processed.

A good example of a flat file is a single, text-only file that contains all the data needed for a program. They can be harder to update, contain non-unique records, have increased potential for duplication, and over time, can become inefficient.

Flat File data format (FF/EDM) – FF/EDM is a spreadsheet-compatible, comma separated values (CSV) file format whose content is specified by NAESB standards. All the rows in the flat file database follow the tuple concept in relational algebra, where tuples are an ordered list of elements. CSV files are files where table data is gathered in lines of American Standard Code for Information Interchange (ASCII) text with the value of each table cell separated by a comma, with each row represented by a new line. While it uses a simple structure, a flat file database cannot contain multiple tables like a relational database can. Simple systems can easily contain basic information for a quick database.
