Thank you for your help Jos this week.
I feel like I've come a long way since HelloWorld.java
Just out of curiosity, What would a databse program cost (read, write, edit, delete, search options with it as well as creating an invoice with the fields entered). Just wondering if it's time to get a job in this field?!!
You're welcome of course; Java 1.6 comes bundled with JavaDB which is Sun's version (read: clone) of Apache's Derby database system; it's a complete SQL engine and it can do everything you described above and then some. It costs you nothing.
You at least need to know something about table normalization (e.g. Boyce Codd normal forms etc.), views on (joins of) tables, transactions etc. to get a decent job in the database field.
kind regards,
Jos
