PPT-Implementation of relational operations

based on slides from UC Berkeley Join Operators Join Operators Joins are a very common query operation Joins can be very expensive Consider an inner join of R and S each with 1M records Q How many tuples in the answer. Takeoff speeds are a safety key element fo r t of an d en able pilot sit at ion l awareness and decisionmaking thi very dynami c si tuati n The use of erroneous takeoff speeds can lead to tail strikes highspeed rejected ta keoffs or initial climb w Also formal definitions of insertion anomaly and deletion anomaly are presented It is shown that a schema is in DKNF if and only if it has no insertion or deletion anomalies Unlike previously defined normal forms DKNF is not defined in terms of trad Patricia A.
