ExDRa - Exploratory Data Science Over Raw Data

The idea of the ExDRa project is to investigate suitable system support for the exploratory data science process on heterogeneous and distributed raw data sources and to provide it as part of a prototype for real-world use cases. In detail, the approach includes the following main research areas:

  • Ad-hoc and federated data integration over raw data
  • Data organization and reuse of intermediate results
  • Horizontal optimizations across the entire data science life cycle
  • Request planning for limited access to data
