Dummy Data

Dummy Data. Dummy data is a information that does not contain any useful data but serves to reserve space where real data is nominally present Dummy data can be used as a placeholder for both testing and operational purposes For testing dummy data can also be used as stubs or pad to avoid software testing issues by ensuring that all variables and data fields are occupied.

Generate and download fake/dummy data to populate your database for development or testing.

Dummy data isn’t exactly dumb — on the contrary Analysts that use dummy data are often the smart ones in the room since dummy data is kind a safety mechanism for data integrity It’s a trial subject of sorts applied to unknown programs or program modifications before valuable data is used.
