Competencies / intended learning achievements

After successful completion of the module, students will be able to
  • formally describe and compare common consistency models,
  • understand and explain how classical concurrent and replicated data structures work,
  • explain and justify the limits of non-blocking synchronization,
  • separate application areas of replication in distributed systems.
