If you change the DBMS being modeled, the model will be altered to conform with the new DBMS as follows:
-
All data types specified in your model will be converted to their equivalents in the new DBMS.
-
Any objects not supported by the new DBMS will be deleted
-
Certain objects, whose behavior is heavily DBMS-dependent may lose their values.
Note: You may be required to change the
DBMS
if you open a model and the associated definition file is unavailable.
