These are common algorithmic solutions for deadlock prevention.
This requires Derived Horizontal Fragmentation using the join operation. We define the fragments of ASG based on the fragmentation of PROJ .
Assume PROJ is horizontally fragmented by location:
Option 1: (R1 ⨝ S2) then with T3
Suppose we have a distributed database system with three nodes, each storing a different fragment of a large database. We want to process a query that retrieves all customers who have placed an order for a specific product.
Basic TO rule for write_TS:
. A common exercise involves detecting "Global Deadlock" using a Distributed Wait-For Graph. Reliability & 2-Phase Commit (2PC):
