At this point, you have a database server, but you have no database to store your data. To create a database, we will connect to the network server through the ij interactive JDBC tool and create our initial tables.
bash$ . setNetworkClientCP.ksh
bash$ sh ij.ksh
ij version 10.1
ij> connect 'jdbc:derby://localhost:1527/MYDB;create=true';
You should now see a directory called MYDB.
