Some predaddy components can be used in any projects regardless of the fact that you are using DDD or not. I have got several ideas from [Google's Guava EventBus](http://code.google.com/p/guava-libraries/wiki/EventBusExplained) and [Axon framework](http://www.axonframework.org/).

Some libraries are used which are just API libraries and you must care for their implementations:

1. [lf4php](https://github.com/szjani/lf4php) for logging. Without an implementation predaddy is not logging.
2. [trf4php](https://github.com/szjani/trf4php) for transaction management. In most cases you will need to use a trf4php implementation (eg. [trf4php-doctrine](https://github.com/szjani/trf4php-doctrine))
