+
+1) Download and install the PostgreSQL database,

+
+2) Dependency for postgresql-driver included in Petclinic pom.xml file.
+ Alternatively, download PostgreSQL JDBC driver from here: https://jdbc.postgresql.org/download.html
+   and copy the PostgreSQL JDBC driver JAR file (e.g., postgresql-9.4.1211.jre7.jar) into
+   the db/postgesql directory.  
+
+3) Create the PetClinic database
+ 
+	CREATE DATABASE petclinic

+       ENCODING = 'UTF8'
+       TABLESPACE = pg_default
+       CONNECTION LIMIT = -1;
+       
+ and execute the "db/postgresql/initDB.sql" script, then execute "db/postgresql/populateDB.sql"
+
