To create a new database, user leverages the 'Export' feature of HSQLDB

Create your data model and when done, click the 'Database Connections' icon as shown below:a.

b. In the DB connection set tings dialog box, enter information as shown below ( in this case, 'centerice' is the new data model

name and that is also the default name of the underlying HSQLDB we are creating). Because this is the very first time we

create this database, we need to check "Is New HSQL Database" checkbox! Click 'Export' will bring the DDL for dropping

tables (if applicable) and table creation script for user to verify. Just click OK to proceed with exporting the data model. See

the second screen shot below.

e. Click 'Save'. This will update the system's property to point to your newly imported project's web app root and therefore the

new HSQLDB directory. Note: you do NOT need to do anything in this dialog box, just clicking the 'Save' button will fulfill your
