Many companies already have some established architectural design patterns which are supposed to be used in most of their applications. For example it makes sense to standardize the layering of business components. It also makes sense to establish specific rules how one business component can access another one. In the upcoming 9.4 release of Sonargraph-Architect we implemented a new feature in our architecture DSL which should make it very easy to add generic architectural blueprints to a quality model which would allow automatic verification of those architectural design patterns on any business component without having to create a component specific architecture.
In modern object-oriented languages, inheritance is massively used with its pros and cons. Moreover, languages such as Java offer simple inheritance but also allow classes to implement an arbitrary number of interfaces. With inheritance and interface implementation comes one additional ingredient that is naturally expected: method overriding. When a software evolves, you end up with hierarchies involving multiple classes and interfaces with methods definitions and implementations and then, the classes that are part of this hierarchy will be used by some other classes. In this context, it is difficult if not impossible to have control by hand over the usages or overriding classes of methods we would be interested in. Hereafter, I will present this problem in more detail with a very concrete and yet complex enough example, as well as some tools that can empower software architects and developers to gain more control over their code.
