class-design

Let me introduce my situation:

I have Java EE application and in one package, I want to have classes which will act primarily as cache for some data from database, for example:

class that will hold all articles for our website
class that will hold all categories
etc.

Every class should have some update() method, which will update data for that class from database and also some other methods for data manipulation specific for that data type.

Now, I would like to call update() method for all class instances (there will be exactly one class instance for every class) from one place.

What is the best design?

I read this question and it got me thinking about another fairly recent thing. Object oriented languages.

I have been programming for many years but I am still not comfortable with the concept of "Interfaces". I try to use interfaces but many times I don't see a mandatory use for it. I think this is probably because the projects weren't so big, or because interfaces are more useful when teamwork is involved… >>> More
