What is a coded application?

A application is an interface that lets people connect to data and insights through a front end application.  An application does not have to have a graphical user interface either.  An application can also be a coded program that can help with moving data or connect to an API to perform some sort of service like data cleaning, data moving, or data quality.  Windows is an example of a GUI operating system, and DOS is an example of an application without a GUI that can do functionality like you can do in windows.
