Dominique Hausler

I am currently working as a PhD student in the DFG Project NoSQL Schema Evolution and Big Data Migration at Scale II. My work contains the analysis of graph databases, in particular evolution in graph databases. To do so, I am analyzing the evolution capabilities of graph databases and plan to develop on top of Cypher an evolution language. The second topic focuses on inter-model linkage. The aim is to develop a system where different database stores with heterogeneous schemas can be accessed at once. To connect different data models, inclusion dependencies are used.
