Cooperative transaction management for XML

This research project is funded by Deutsche Forschungsgemeinschaft (DFG).

The requirements of the media production process, as a current non-standard application of database technologies, can only be complied by classical relational database systems in a limited way. In addition to the necessity of a flexible but transactional management of hierarchical (scene) structures, the support of a cooperative working process is required in wide fields of possible system and distribution scenarios, ranging from small work group solutions to world wide acting production scenarios. The goal of our work is, starting from a concrete media process - the sound production for movies - and the current state of transaction management technologies, to develop technologies for implementing cooperative transaction models. Therefore, appropriate architecture variants are considered and concrete synchronization and change propagation concepts, which meet the special requirements, have to be developed and evaluated.
