In the New Database
Connection dialog, provide the Database URL as jdbc:derby://localhost/iepseDB,
user name as iepseDB and password as iepseDB and click OK.
When you have connected successfully with the DB, browse the tables in iepseDB. All
of the tables are auto-generated and you are not expected to alter or delete any of them.

A CURRENTITINERARY table is also created. This is the name specified in the
Global property field in the Table Output IEP operator.
Note that along with the CURRENTITINERARY and EMS tables, there
are other tables starting with 'Q'. They are data tables that store the
current output of the operator. There are two basic types of data tables:
one for output types and one for relation types. You are not expected to
alter these tables.
When the IEP is invoked, the stream data is stored in the
CURRENTITINERARY table.
The IEP example shown in this chapter needs a stream input simulator
to test the IEP process. The source code bundle provided in the site has
a TestItineraryIEP NetBeans project that reads an external data file and
sends a data stream to the IEP module. The project is available under
src\PartG\TestItineraryIEP.
