The object is not the primary citizen, instead the class is the primary artifact. In most mainstream OOP languages, Objects are derived from classes, not that classes are assigned to created objects. Therefore, we think it should have been called Class Oriented Programming. We can also see this class focus in many of the technologies in Java today: in Spring you declare -class names in application contexts, JSP uses class names to declare beans and so forth.</p><p>This in turn leads to that there is no good OOP solution for the problem we describe below.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_behavior_depends_on_context_2"></a>Behavior depends on Context</h4></div></div></div><p>Once you start thinking of "Behavior depends on Context", you have a hard time understanding how people for the last 20 -years or so of Object Oriented Programming (OOP) has ignored this fact.</p><div class="section"><div class="titlepage"><div><div><h5 class="title"><a id="_who_am_i"></a>Who am I?</h5></div></div></div><p>When I sitting in front of the computer, I am a software developer, but if I go out in the jungle, I am suddenly +class names in application contexts, JSP uses class names to declare beans and so forth.</p><p>This in turn leads to that there is no good OOP solution for the problem we describe below.</p></div><div class="section" title="Behavior depends on Context"><div class="titlepage"><div><div><h4 class="title"><a id="_behavior_depends_on_context_2"></a>Behavior depends on Context</h4></div></div></div><p>Once you start thinking of "Behavior depends on Context", you have a hard time understanding how people for the last 20 +years or so of Object Oriented Programming (OOP) has ignored this fact.</p><div class="section" title="Who am I?"><div class="titlepage"><div><div><h5 class="title"><a id="_who_am_i"></a>Who am I?</h5></div></div></div><p>When I sitting in front of the computer, I am a software developer, but if I go out in the jungle, I am suddenly hunter-gatherer and prey.

When an object is stored in the database it is of a different class, than when it is transported to the client and possibly when it is displayed in the GUI. We see the effect of this problem in many of the design patterns and so called "best practices" -in Java EE development.

In reality, however, we have found that classes becomes tightly coupled with many other classes in their neighborhood, leading to impossibilities of single class re-use. Many tricks are introduced to minimize the "Coupling Hell", such as Inversion of Control and Dependency Injection. Although those tools are good, the underlying problem remains.</p><p>Why do we end up with large coupled class network graphs?</p><p>Essentially, it boils down to "scope". Classes are too large, their scope is too large, and for each small functional unit within the class, there will be additional coupling to other classes. And this often progresses to the full -boundary of the entire domain the class remains in.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_application_layer_impedance_mismatch"></a>Application layer impedance mismatch</h4></div></div></div><p>Almost all technologies used in modern software development, starts by looking at an infrastructural problem and try to +boundary of the entire domain the class remains in.</p></div><div class="section" title="Application layer impedance mismatch"><div class="titlepage"><div><div><h4 class="title"><a id="_application_layer_impedance_mismatch"></a>Application layer impedance mismatch</h4></div></div></div><p>Almost all technologies used in modern software development, starts by looking at an infrastructural problem and try to solve that the best way.

We think that increasing abstraction often also increases complexity, and that the abstraction benefits are somewhat linear whereas the complexity negatives are exponential. So, our conclusion is that by making no distinction between different kinds of objects, many sound technologies run into incredibly difficult problems. The implementation of the programming platform (e.g. Java) is of course easier to implement with a hefty amount of scope reduction into as few as possible abstractions. But that is not the situation for the user. The abstraction is then required to be reversed when the rubber hits the road, e.g. ORM mapping must be declared explicitly by the programmer, often using separate tools -and languages.</p></div><div class="section"><div class="titlepage"><div><div><h4 class="title"><a id="_solution"></a>Solution</h4></div></div></div><p>We think the solution was expressed more than 2500 years ago, first by Indian scholars and slightly later by Leucippus +and languages.</p></div><div class="section" title="Solution"><div class="titlepage"><div><div><h4 class="title"><a id="_solution"></a>Solution</h4></div></div></div><p>We think the solution was expressed more than 2500 years ago, first by Indian scholars and slightly later by Leucippus and Democritus.
