Hi Rickard
A made the abstraction of having a data layer, business layer
and a environment layer in object level. Basically the business
object is a pure java class with no dependencies other than a VM.
This functionality can be tested on each own with a unit test.
This object can then be wrapped up by a servlet, EJB or
Jini wrapper. The wrapper will just extend the business
object, inheriting all the business methods. The wrapper
itself then add all the functionality in order for this
object to exists in whatever environment. The data that
the object accesses, is also abstracted into a data access
object (DAO). At the end of the day you end up with a mini
three tier architecture where you have your DAO, Business object
and environment wrapper. Each of these will have a unit test.
In this way your business logic is nicely abstracted and environment
independent.
Your thoughts on this?
