Subject RE: How to shutdown with authentication
Date Fri, 29 Jun 2007 18:02:01 GMT
I might add that MYSQL's commercial license is very expensive. So
expensive that it precluded its use
in my case. It is true that Derby is not in the same league as MYSQL,
but it is better than writing your own
file system.
I use Derby in both embedded and client-server applications. I was
pleasantly surprised at the response time
the client-server model gave me. It is used in a LAN application, but
there was still no perceptable difference
between the response time of the client-server and the embedded mode. It
works great using a Windows client and
a linux server. All the code is on the client machine and the server
just has the Derby jar files. I have enhanced it
as of late and added some administrative functions on the server written
in Java with a GUI interface using the Swing

I can't answer for Leonard, obviously. But it could be beacuse:

A) He wants to embed the db in a java app, but also let remote clients

B) It may because he wants to be sure that the DB runs anywhere Java

C) Maybe he needs to deploy his DB server on many different machines and
likes that fact that he only needs to install a couple of jar files

D) Maybe he cannot use MySQL's dual GPL/commercial licence for some
