Outperform the Standards: O/R-Mapping im open-EIS 5.0

Erweiterungen gegenüber der J2EE-Spezifikation ermöglichen hohe Performanz

(PresseBox) (Chemnitz, )
Open-EIS hat als Bestandteil einen open source Applikationsserver, welcher auf Java-Architektur basiert und sich an der J2EE-Spezifikation orientiert, aber einige wichtige Erweiterungen (gegenüber J2EE) mitbringt. Ansonsten besteht open-EIS aus einer standardkonformen modularen 3-Schichten Java Architektur, mit Präsentations-, Geschäftslogik- und Datenhaltungsschicht.

Warum sind diese Erweiterungen notwendig? Neben allen Vorteilen von J2EE gelten Entwicklungen, die sich konsequent an diesen Standard halten, zu recht als sehr teuer und das Ergebnis oft als viel zu langsam (unperformant). Dies gilt insbesondere, wenn Datenbanken in die Lösungen involviert sind. Warum dies so ist, soll ein kurzer Vergleich erläutern: Wenn die „Regeln“ es fordern, kann man natürlich gyig golq „wejrgs vuakdiye“, yhvb lcq 6 f „uazxu ikkclff“.
