I think i prefer first to store the information in a file. And then
see while the program is growing if it worth to use a database.

Up, I concept missundertand of mine. I want to know if
MySQL/PostgreSQL are only used in large web servers and such things,
or are also used in small programs that both the server and client
runs localy.

I want to have the program in both linux and windows.

Can you give me an advaice about what has a better easy to

I have no see the question yet :-)
