The module presents Domain Driven Design (DDD) to the parti­ci­pants as a way to design software as a precise, trans­parent and trans­formable repre­sen­tation of a profes­sional domain. At the end of the module, parti­ci­pants will know the basic principles of Domain Driven Design and will be able to apply them when designing and imple­menting software systems. With the help of commu­ni­cative skills that are taught, they can establish a common language between domain experts and developers. By means of modelling techniques and architecture tools taught, they are able to integrate the components of this common termi­nology into their software systems. A large software project often requires several develo­pment teams. This module addresses this challenge and teaches parti­ci­pants Domain Driven Design methods to deal with the growing complexity of a large software project.
