/*!

 * \brief qx::dao::strategy : class inheritance strategy and database (Concrete Table Inheritance is the default strategy used by QxOrm library)
 *
 * With ORM tools, there is usually 3 strategies to manage inheritance and database :
 * - Single Table Inheritance
 * - Class Table Inheritance
 * - Concrete Table Inheritance
 *
 * QxOrm works by default with Concrete Table Inheritance strategy (others are not supported yet).
 * Many tutorials and forums are available on internet to more details about ORM inheritance and database.
 * You can find a sample in the directory ./test/qxDllSample/dll2/ with the class BaseClassTrigger.
