what is agile development framework

Agile is the name of a software development methodology that calls for rapid iterations through the traditional software development life cycle (analysis, design, development, testing, acceptance). The term was coined when a group of programmers came together and published the Agile Manifesto back in 2001.

Agile software development methods are ways of breaking down and splitting up the problem that lets you adapt to rapidly changing requirements.

An agile development framework is a software development framework that encourages working in an agile manner.

You might want to look into the MVC pattern of writing software. The idea is to split the logic away from what is viewed. I don’t really want to get into it but this link might help.

MVC—while an excellent way of organising code—doesn’t really have anything to do with Agile.

Agile software development is a competitor to Waterfall.

Agile is characterized by the quick communication and the huge involvement of the client (be it an internal stakeholder or a real client) in the development phase.
