Domain-Driven Design in PHP

NoSQL

What about NoSQL mechanisms such as Redis, MongoDB, or CouchDB? Unfortunately, you can't escape these problems. In order to persist an Aggregate using Redis, you need to serialize it into a string before setting the value. If you use PHP serialize/unserialize methods, you'll face namespace or class name refactoring issues again. If you choose to serialize in a custom way (JSON, custom string, and so on.), you'll be required to again rebuild the Value Object during Redis retrieval.
