Title:
Towards a Better Organization of Programs

Speaker:
Karl Lieberherr

A common problem in software is that programs are a tangled 
artifact of several design concerns. This makes them hard
to understand and maintain.

In this talk we will present an approach to programming in the
Java programming language that allows many (not all) concerns
to be expressed loosely coupled rather than tangled together with
other concerns. This leads to programs that are
less tangled and that are easier to understand and maintain.

We show an important separation of structure from behavior that is
based on the Inventor's Paradox. The Inventor's Paradox is about
problem solutions becoming easier when we solve more
general problems. We apply this idea
to programming and show that programming becomes easier if 
we write the programs for generalized object structures rather than specific
object structures.

We will demonstrate how to keep an important family of design concerns
separate in Java programs that are written with the DJ Package.
