Mobile Apps with HTML5 and PhoneGapThis presentation was held at the Agon Solutions annual technology meetup 2013. It focuses on the capabilities and power of HTML5 and how it can be harnessed for the implementation of hybrid mobile applications. I am absolute convinced that HTML5 web apps are the only sensible way to build mobile apps, above all in order to avoid multiple implementation for different platforms. The talk also explains how the framework PhoneGap (Apacha Cordova) works and how it can be used e.g. in conjunction with Sencha Touch.
Agile Project ManagementI gave this talk at the Lufthansa Online & Mobile Lab 2012. The slides start off with the term "uncertainty" and why we need agile management to handle uncertainty and reduce risk. Then I present the argument of information growth during project lifetime which directly needs us to the necessity of anticipation and adaption. My main point is, that - in order to sensibly being able to adapt - you need correct documentation and a solid software architecture.
Proactive requirements engineeringThese slides were presented at the Agon Solutions Technology Workshop 2010. I argue in favor of planned and organized requirements engeneering and give reasons why this is worthwhile. Furthermore, I present a special approach called proactive requirements engineering which heavily build on agility and communication.
Architecture for mobile applicationsThese slides were prepared for a talk at the Agon Solutions Technology Workshop 2011. The presentation gives an overview about the technology development in the mobile market and describes four different architectural approaches for mobile application. Additionally, pros and cons for each architecture are presented.
Important aspects of Quality ManagementThis presentation was delivered at an internal meeting of a customer in the aviation business . It mainly argues why quality management is important. Moreover, it describes the different, contradicting goals of quality management and how they can be balanced in an iterative project.
Enterprise portals with LiferayThis presentation was was given at the 2nd LUGD (Liferay User Group Deutschland) meeting in March 2009. In this talk I highlighted variuous important aspects of web portal implementation (like SSO and timeout management) and showed how Liferay was utilized to achieved the conceptional goals in the Zeppelin projects.
Datenpressen - Crystal Reports und BIRT im VergleichThis article was published in iX 10/2008. It compares the leading Report Editors/Reporting Engines Crystal Reports and BIRT (Opensource). It is based on concrete project experience at Zeppelin Baumaschinen GmbH and GI (Gesellschaft für Informatik).
Opensource Portal-Entwicklung mit LiferayAn article I wrote for the Magazine JavaSPEKTRUM describing the way how a employees portal was build at Zeppelin Baumaschinen GmbH. In this project, headed by me as project lead, we used the opensource portal server Liferay. The article was published in JavaSPEKTRUM.
Application integration in enterprise portals - methods and challengesToday, Internet Portals are important platforms for enterprise communication and process integration. Neverthelesse, they can only unfold their full potential when services and applications are integrated. This paper describes the basic principles and the essential methods of application integration and explains the consequences for the applications to be integrated.
Writing and using UFLs for Crystal ReportsThis paper describes in detail how to use and create user function libraries (UFLs) for Crystal Reports, mainly concentrating on version XI and C++ UFLs. The document shows how to configure the software to use a custom DLL and also describes how to build a new one from scratch. Source code snippets are included.
Using Crosstabs in Crystal ReportsThis paper summarizes how to build and use crosstabs with the well-known Crystal Reports reporting tool. Especially, it focuses on getting around certain limitations in the Crystal Reports crosstab, e.g. integrating images and dynamically changing the facts and dimensions in the crosstab. There is also a german version of the paper.
Von der Idee zum Projekt - Möglichkeiten und Grenzen der Model Driven ArchitecturThis article was written for the book Software Engineering Live which was published by Oldenbourg in 2005.

Performance beim DatenbankimportIn most software projects there is the necessity to import data into a relational database system. One of the most important aspects of this is the performance for most of the projects deal with mass data. This paper describes the aspects which influence the performance of data import most. It gives insight on how to use the different strategies and when to avoid them.
Generierung einer Datenbankstruktur aus C++This document deals with the problem, how to structure and store information about the data dictionary in such a way, that big relational database schemas can be genrated from C++ code, without interfering with the maintainability of the system.
