Pehapkari.cz: Domain-Driven Design - Language

On the Pehapkari.cz blog today they've posted an article about something that, while not directly related to the code of your application, can help to improve the end result: defining a common language for domain-driven design.

Domain-driven design is a software design that focuses on understanding underlying business. It is useful for long-term projects because it leads to high-quality software that serves users. It helps when dealing with difficult problems, keeps track of core problems and prevents us from getting lost in the code.

The author starts the article by talking about issues before adopting a domain-driven design process and briefly describes what DDD is and what its goals are. The post then gets into some the basics behind defining your own domain and gives an example of definition of "account" and "price" for an e-commerce application. It then goes on to talk about goal of creating a ubiquitous language for the product that also includes functionality and process, not just the objects in the system.
