Aggregate-Oriented Modeling with DDD and NoSQL

Many of the problems encountered in scaling, parallelizing and distributing systems that tend to be addressed in ad-hoc ways are actually deeply connected with the manner in which the business domain has been modeled. Domain-Driven Design (DDD) has rich modeling resources for tackling concurrency, transactional and distribution boundary issues within the domain model itself, enabling teams to be more effective in dealing with business complexity and change.

Learn about how aggregates can enrich your domain models, improve system performance and loosely couple your systems. We will give examples of how aggregate design choices are manifested in NoSQL data schemas, focusing particularly on MongoDB, and the consequences of making these choices for domain modeling, performance, and scaling.
