Suppose that a large store has a transactional database that is distributed among four locations. Transactions in each component database have the same format, namely Tj {1,..., im}, where Tj is a transaction identifier, and ik (1 ≤ k ≤ m) is the identifier of an item purchased in the transaction. Propose an efficient algorithm to mine global association rules. You may present your algorithm in the form of an outline. Your algorithm should not require shipping all of the data to one site and should not cause excessive network communication overhead.

:
. Suppose that a large store has a transactional database that is distributed among four locations.
Transactions in each component database have the same format, namely Tj {₁,..., im}, where Tj is
a transaction identifier, and ik (1 ≤ k ≤ m) is the identifier of an item purchased in the transaction.
Propose an efficient algorithm to mine global association rules. You may present your algorithm in the
form of an outline. Your algorithm should not require shipping all of the data to one site and should
not cause excessive network communication overhead.
