Pattern I:
how to connect to the database?
1. load the embedded driver;
2. wanna create a DB? then set some properites;
3. create and connect to the database using DriverManager;
how to operate on the DB?
1. create a statement from the connection;
2. execute the statement and put the results into result set;
3. do something on the result;
some cleaning work?

Pattern II:
How it works?
It is just for application of different JVM, the classic client/server framework.
How to develop?
Client-code: nothing serious difference from the embedded pattern, other than some String arguments;
Server-code: just run a command to start up the server.
