Forschungszentrum Informatik (FZI)

Developing an application for the Business Process Monitoring (BPM) tool HORUS at the Research Center for Information Technology (FZI) in Karlsruhe

The application automates mapping real resources from the FZI Active Directory (AD) and integrates them into HORUS
First, I analyzed the FZI AD, read all data, and built an Eclipse Modeling Framework (EMF) model based on it
The resources from the Active Directory were then initialized as EMF objects or entities in Eclipse and persisted in an XML file
Properly handling updates in the AD and relationships between all resources was important during persistence
Different data structures from the Java API were used for this purpose
Other tasks in this project included:
Adjusting a logging component for business process simulation
Implementing changes to logging for file formats (XML schema)
Implementing, evaluating, and analyzing application code
