One year ago, we published a set of slides about the main concepts implemented by our framework.
Mainly about ORM (and ODM), NoSQL, JSON, SOA, MVC (and MVVM), SOLID, DDD, CQRS and some patterns like Stubs, Mocks, Factory, Repository, Unit-Of-Work.
Worth a look, if you want to find out the benefits of the latest software development techniques.
They try to open the landscape of any Delphi developer (probably with a mostly RAD and OOP background) to some new areas.

I just updated the slides from our public GoogleDrive folder.
They now reflect the latest state of the framework (e.g. ORM real-time synchronization, asynchronous callbacks, DDD CQRS services...).
They have also been polished after several public presentations, since I used them as base for trainings I made for some European companies.

If you want to go further, or have some more enlightenment, ensure you took a look at our framework Documentation, which would detail all those patterns, and how mORMot may help implementing them for your projects!

Feedback is welcome on our forum, as usual!
