Talk Description:

Software development is not just about translating business requirements into a static software design. It is about ensuring that in the long run, the system can evolve with the business needs and facilitate communication between business people and developers around the business domain in order to quickly and accurately add or modify features. This requires superb knowledge crunching and domain modeling skills.

Domain Driven Design is an approach that Eric Evans popularized in the mid 2000s to address these concerns. It is a process that centers design of software around the business domain.

This presentation will cover several of the topics and ideas in the Domain Driven Design approach (but not all topics of the book):

• Domain Modeling
• The Ubiquitous Language
• Model Driven Design

Additionally, there will be a few code examples to illustrate some of the Domain Driven Design ideas as applied in a Ruby on Rails application.
