Show your work—just showing the final answer is not acceptable. For each iteration show the candidate and acceptable frequent itemsets. You should show your work similar to the way the example was done in thePowerPoint slides.(b)List all of the strong association rules, along with their support and confidence values, whichmatch the following metarule, where X is a variable representing customers and itemi denotes variables representing items (e.g., “A”, “B”, etc.).x  transaction, buys(X, item1)  buys(X, item2)  buys(X, item3)Hint: don’t worry about the fact that the statement above uses relations.

When you use a transaction, the database tables/views/other resources used in the transaction are locked until the transaction is either committed or rolled back in order to ensure all modifications are either ALL made, or none of them made. Usually databases also have options on the level of locking used such as no one can read or make changes to those resources when locked, or users can’t make changes to the resources but they can read data in the tables/views/read access to resources. Pick a potential problem with database locks on tables/views/resources and one popular way database administrators and / or database users use to address that problem?
