/** \defgroup fost_orm fost-orm

    \brief This package contains implementations of various concrete persistence layers for Fost and the abstractions that allow them to operate together.

    The database back ends are designed to work with both relational databases (RDBMSs) and non-relational databases. The back ends are also designed to be layerable, where one layer adds on the functionality of the layers below it. This library includes a simple transactional JSON database with minimum features.

    The abstraction layer is able to handle both dynamic models (i.e. the models are defined at runtime, possibly through introspection of an existing database), static models (the models are defined more or less as normal C++ classes with special annotations) and a mixture of the two (static models augmented with dynamic fields).
