One of the main advantages of a flat file based system is having all of the available data in the same location. This setup makes the data very readable and understandle to anyone who has access to the file. A "flat file" database allows the user to specify data attributes (columns, datatypes, etc) for one table at a time, storing those attributes independantly of an application. There would need to be multiple users accessing the data to process the amount of updates we would generate. A relational database uses multiple table structures, cross-referencing records between tables. Include the pros and cons of the relational database format and the flat file format. A flat file database is a one record per line text file, a binary file (or a combination of both text and binary) file which separates columns by using "delimiters" which separate the fields in a standard recognisable way. The expense of maintaining and even setting up a database system is relatively high and one of the drawbacks of relational databases.

A flat file is a text file that stores a single record per line with each piece of information separated by a comma — its data structure is self-contained and limited. Relational databases are far more flexible (though harder to design and maintain) than what are known as flat file databases, which contain a single table of data. Flat files are easy to create and use (for small amounts of data). These tables provide a systematic way of accessing, managing, and updating data. A relational database is one that contains multiple tables of data that relate to each other through special key fields. This means that all the data available is within any given record. Think of flat files as being similar to the files in a file cabinet drawer—a collection of single records each containing standalone data. These databases can support a variety of data models, including key-value, document, columnar and graph formats.
