Database Datatypes
Using Enterprise Architect's 'Database Datatypes' dialog, you can add to the set of data types that are available for a particular DBMS. You can:
- Identify the DBMS in use and, if required, set this as the model default
- Include any new data types that are supported by later versions of the DBMS and not yet included with Enterprise Architect
- Remove any previously-added data types that are no longer relevant
- Add a new DBMS product and its built-in data types if, for example, you want to create a physical data model for a DBMS product that is not yet supported natively by Enterprise Architect
