Architecture, to build an app, or a house, it's important. But what is that concretely?

MVVM, MVP, Clean Architecture, Baroque, Multitier, you hear those words at every conference, at work, or anywhere else, but maybe you don't really know what it is? Or you are not sure why you should you a certain type of Architecture instead of another?

In this talk, I want to give you all the tools to know about architecture and I want to show you an overview of the most commun type of architectures we are using in the mobile world.

2. Why am I doing this talk?
3. Architecture, to build an app, or a house, it's important. But what is that concretely? Antoine Danois | @antoinedroid A bit of history START 1960s - Structured Programming - The comparison between software design and (civil) architecture was first drawn 1950s Non-structured Programming – Assembly late 1960s - Layering: 1 tier with the UI, Business Logic and Data Storage 1970s - Procedural / Functional Programming - Pascal / C
4. Architecture, to build an app, or a house, it's important. But what is that concretely? Antoine Danois | @antoinedroid A bit of history 1980s - Object Oriented Programming - C++ - Perl 1979 Model-View-Controller 1980s - Layering: 2 tier, the 1st tier with the UI, the 2nd tier with Business Logic and Data Storage
5. Architecture, to build an app, or a house, it's important. But what is that concretely? Antoine Danois | @antoinedroid A bit of history 1990s ~1991 – Python ~1993 – Ruby ~1995 – Delphi, Java, Javascript, PHP 1996 Model-View-Presenter 1990s - Layering: 3 tier, the 1st tier with the UI, the 2nd tier Business Logic (and the UI presentation logic in case of a browser as client), the 3rd tier with the Data Storage 1997 Web services
