Design Patterns in Database Applications with Java (JEE / JSE)

Hello everybody, I've been reading StackOverflow for quite a while now and I'm only now building the nerve to ask a question. I'm 20 years old and currently enrolled in college in IT here in my hometown (Cluj-Napoca, Romania). Enough for introductions :D.

Basically I have my little software firm that provides Book-keeping appz. They're (horrifyingly) written in Delphi and I want to start from scratch and write them in Java. I've had little experience with Java in the past but I want to learn and I've chosen Java because of the cheap and quality tools the platform offers.

Now could you please point me to the right direction as where could I find some complete documentation (books, web-sites, blogs etc) as where to get some info on properly building database applications including design patterns with DBs(my choice is PostgreSQL and have already ordered a book) and also Java. I know I won't be able to get it right the first time but at least get it close to right.

Thank you

Head First Java is a great place to start.

also agree with moritz!

Thank you Chris, will try to get my hands on this book also

I think I'm also going to get Head First Design Patterns. Is it good?

Yes, it's excellent! However, I would recommend waiting until you have completed a few projects first. You will get more out of the book if you have some experience and cases to relate it to. I actually think Design Patterns may lead you down the wrong path if you don't have sufficient experience to guide you (i.e. you may get "pattern fever"). So, spend at least a year of two doing development and then go pick up a copy of design patterns.

ok... will do that. Thank you Chris

But... aren't patterns like MVC useful to start with? I may be new to Java but not really new to programming. And I would like to build the appz in Java properly and following good patterns.

First of all: welcome at so :-)

There are a lot of good and free resources covering Java as a language ( e.g. wikibooks ), and the reference documentation by Sun is also quite comprehensive. Once you have understood the basics of the language, I think its time to dive into the depths of database applications, and patterns. How?

First of all, you should try to build some simple database schemes, "playground"-scenarios are helpful from what I can tell. Imagine e.g. a library and try to model that. It doesn't take long yet you will learn a lot.

For patterns, I generally think of them as a guide, like the MVC pattern which you will likely incorporate. Don't force yourself to use them all in the first place, try to understand one at a time and refactor your code to have some pattern represented there rather than writing to a pattern in the first place.

So, good luck! ( and of course, once you're stuck, just ask! )

Thanks a lot, also for the quickness of the answer. I have a few books ob the language itself which I read but that's just the tip of the iceberg. Will look more into MVC and what's it all about. Again thank you

Martin Fowler's "Patterns of Enterprise Application Architecture" is quite popular.

Thank you. Will add it to the "to read" list
