Pre 1946 school desk
restore the wood, but preserve the markings dating back to 1946, 1947,
1948, 1953 and 1955. I will also keep the metal on the original
condition. The sits fold. Oh, and by-the-way, it is very comfortable,
I can sit in it just day-dreaming.
DAO: creating new model
1. Write a model class with annotations. 2. Run hibernate3:hbm2ddl to create database scripts. 3. Write DAO interface. 4. Write jUnit test for DAO and make sure that they fail initially. 5. Implement DAO. 6. Pass jUnit test with all possible inputes to verify that DAO methdod work.

Baby Steps
Good code is a succession of small programming steps that would eventually create a well-written functionality.
In order to create a clean, simple, and functional code, it is good to follow some of the best practices of programming:
Let's say we want to create UI with following functionalities:
- List
- Add
- Edit
- Delete items
1) Create a skeleton UI with "comming soon.." text, you test and commit code.
2) Make a fake, hardcoded list and you display it , you test and commit code.
3) Fetch the list via a service call that returns a fake list, , you test and commit code.
4) Implement the DAO , you test and commit.
5) Connect all pieces, you test and commit.
Now you have the "list" and you can move to the "add" functionality.
