 In its default configuration, Petclinic uses an in-memory database (HSQLDB) which
-gets populated at startup with data. Since there is no persistent support, once
-the application is destroyed, so is the database.
-If a persistent database configuration is chosen, make sure to change the datasource
-inside the relevant application-*.xml so that the schema and the data do not get 
-inserted each time the application is started. Additionally, update the jdbc.properties
-file to reflect your change.
