C++ type mapping to from data element types

From class model to logical (ER) data model

Source type			Target type
C++ pre-type	C++ type	C++ post-type	Data element type
	Bool		bit
	byte		tiny integer
	short		small integer
	int		integer
	long		long binary
	float		float
	double		double precision
const	char		character
	char		character varying
const	char	*	long character
	char	*	long var character
	default		long var character

From logical (ER) data model to class diagram

long binary	C++ Types		long
decimal	C++ Types		int
number	C++ Types	unsigned	double
