Mastering the Core: Comprehensive Exercise Solutions for Principles of Distributed Database Systems

Principles of Distributed Database Systems

• Horizontal Fragmentation (HF): Uses selection predicates (e.g., DeptID = 10). Ensure completeness (every tuple goes to some fragment) and disjointness (a tuple belongs to at most one HF fragment, unless replication is used).
• Vertical Fragmentation (VF): Uses projection over attribute subsets. Must include the primary key in every fragment for reconstruction. Ensure lossless-join property.
