DAS C++ has now its own exceptions, such as DASInvalidTypeNameException, DASInvalidPropertyNameException, DASNullPointerException, DASColumnNotFoundException, DASInvalidColumnNameException, DASInvalidRelationshipNameException, DASInvalidSQLTypeException and DASInvalidTableNameException.

DAS C++ is now non-case sensitive, once most dbms are non-case sensitive, DAS C++ will be so, at least for now. Maybe on future, there can be added an option on config file that set DAS as case sensitive. All type and property names are converted to lower case when the SDO graph is created.
