Definition Domain Driven Design

The approach enables the development of software that is focused on the complex requirements of those that need it and doesn t waste effort on anything unneeded.

Definition domain driven design. Domain driven design ddd is the concept that the structure and language of software code class names class methods class variables should match the business domain for example if a software processes loan applications it might have classes such as loanapplication and customer and methods such as acceptoffer and withdraw. Domain driven design is a methodology and process prescription for the development of complex systems whose focus is mapping activities tasks events and data within a problem domain into the technology artifacts of a solution domain. Base complex designs on a model. Proverbe gascon malgache ddd est l acronyme de domain driven design.

Chapter 2 talks in detail about how a domain is divided into bounded contexts and chapter 3 is the best source on drawing context maps.

Domain driven design ddd advocates modeling based on the reality of business as relevant to your use cases. Duplicates showed up in the database some information was not saved at all and you could run into optimistic locking errors anywhere and anytime.

Domain driven design also defines a number of high level concepts that can be used in conjunction with one another to create and modify domain models.
