Note that if you do not specify yourself where the database is to be
stored, it will be stored in current directory.  I am not a Windows
expert, but from your experience it seems like the current diretory
may be the directory where the executable is located.

You can take control of where the database is located in at least two

1. Set the property derby.system.home to the directory where you want
    your database.

2. Explicitly state the location of your database when connecting:

    URL: jdbc:derby:C:/server/javadb10.3.1.4/bin/realty

The server mode works because the default directory when starting the
server will be used regardless of which client is connecting to it.
However, there should be no need to use the client/server mode if you
do not need to support concurrent connections from multiple clients.

Hope this helps,
