Neulich wurde ich angehauen:

Es sei „unschön“, wenn man statt

einfach das schreibt, was man möchte:

Liebe Softwarepäpste und Enterprisearschitekten. Hier kommt meine Philosophie:

• Ich bin faul.
• Die Maschine soll für mich arbeiten.
• Und sie soll das möglichst schnell tun, ohne viel Ressourcen zu beanspruchen.
• Andere Menschen mit weniger Erfahrung sollen das, was ich entwickelt habe, Verstehen und weiterentwickeln können.

Aber nein, so geht das doch nicht. Was wir brauchen, sind möglichst komplizierte Strukturen und Muster, die überhaupt niemand mehr ausser der Autor selbst checkt, damits softwarearchitektonisch schön ist und die Wartbarkeit erhöht wird.

Und wenn man dann genug Singletons mit der Abstract Factory instanziiert hat, welche die Facade durch den Proxy decoraten, damit der Mediator den Observer nicht beim visiten des Mementos dependency-injected, dann kann das Data Access Object mit dem Plugin via Null Object Flyweight durch das Composite iterieren und das emitten, was man eigentlich ursprünglich wollte:

Hello World.

Grässlich. Und dann wird mit einer „höheren Schulbildung“ geprahlt; einer Bildung, wo einem das Hirni dermassen durchgemantscht und verdreht wird, dass man am Schluss überhaupt nicht mehr weiss, wie man einen simplen Text ausgibt, weil man ja erst eine abstrakte Factory braucht, die man dann in einer Implementation per Dependency-Injection instanziieren kann, damit man sie dann durch alle DAO und SOA-Layer rauf und runter über tausend Schnittstellen via XML schicken kann, damit am Ende… Ääh, was wollten wir eigentlich?

Dass so eine Erdölraffinerie* ordentlich Speicher frisst, liegt auf der Hand. Und warten können’s nur solche, die auch so eine Hochbildung haben. Die OOP-Sekte.

Kein Wunder fühlen sich Enterprise-Senior-Supermega-OOP-Engineering-Technical-Softwarearchitekts gleich angepisst, wenn man ihr lange und mühsam erlerntes Hoheitsgebiet mit schnellen, schlanken, praktischen und gut funktionierenden Quickwins erschiesst. Die wollen ihren „Marktwert“ erhalten.

Nein. So will ich nicht enden. Entwurfsmuster als Inspiration ja, aber schlichte Ansätze als „unschön“ bezeichnen, nur weil’s halt grad nicht in ein Enterprise-Pattern passt: FFFUUUU.

* Erdölraffinerie (engl. Gas factory)
Unnötig komplexe Systementwürfe für relativ simple Probleme werden abwertend als Erdölraffinerien bezeichnet.
