  46. * \brief qx::dao::strategy : class inheritance strategy and database (Concrete Table Inheritance is the default strategy used by QxOrm library)
  47. *
  48. * With ORM tools, there is usually 3 strategies to manage inheritance and database :
  49. * - Single Table Inheritance
  50. * - Class Table Inheritance
  51. * - Concrete Table Inheritance
  52. *
  53. * QxOrm works by default with Concrete Table Inheritance strategy (others are not supported yet).
  54. * Many tutorials and forums are available on internet to more details about ORM inheritance and database.
  55. * You can find a sample in the directory ./test/qxDllSample/dll2/ with the class BaseClassTrigger.
