What are Database Files?

A database is a collection of data that has been organized to be accessible and manageable to make data access quick and easy. Database Files are data files that are used to store the contents of the database in a structured format into a file in separate tables and fields. Database files are commonly used by dynamic websites (eg. Facebook, Twitter, etc.) to store data.

There are a number of popular database file extensions, with some of the most popular being “.DB”, “NSF”, and more.
