a. Which itemsets (of any length) are frequent if you know that {ace} and {ad} are the only maximal frequent itemsets? b. If all transactions that contain {bcd} also contain {def}, which of the following itemsets {bcd}, {def}, {bcde}, {bcdf}, {bcdef} are not closed?
The lost update anomaly is said to occur if a transaction Tj reads a data item, then another transaction Tk writes the data item (possibly based on a previous read), after which Tj writes the data item. The update performed by Tk has been lost, since the update done by Tj ignored the value written by Tk. a. Give an example of a schedule showing the lost update anomaly. b. Give an example schedule to show that the lost update anomaly is possible with the read committed isolation level. c. Explain why the lost update anomaly is not possible with the repeatable read isolation level.

The CSM Tech organization has a substantial web presence with several publicly accessible web and application servers. You have DNS servers that handle Internet queries for all your publicly accessible resources. However, after doing some statistics analysis on your public DNS servers, you find that your servers are handling recursive lookups for clients that are not within your organization. Your public DNS servers should handle recursive queries only for your internal clients, but the servers should handle iterative (nonrecursive) queries from external sources. What do you recommend? What are the commands needed to implement the solution?

Each Semuarasa restaurant branch has a mainstay menu that is very popular with customers, so information on the availability of the number of servings is needed to be able to serve orders. Here are two transactions that are ordering a food menu at the same time. T1: Start the transaction at time t1, read 10 servings of food stock at t2. Because ordering one portion, the stock is reduced by 1 at t3. On t6, update the stock count, and commit to t7. T2: Transaction T2 starts a transaction on t2, reads the number of stocks in t3 as many as 10. At t4 orders 3 portions. On t5 it updates the stock to 7 and then on t6 commits it. As a result of the T1 and T2 transactions above, there was an incorrect amount of food stock. Make a solution with 2PL. What kinds of problems happened? Give a reason why choosing this type of problem! How much food is still available?
A job scheduler receives job requests with a priority of execution attached to it,in the following sequence. The higher the priority value, the higher the priority of job execution.Job ID: 464 212 110 840 976 343Priority: 3 2 3 1 2 2Build a treap for the jobs scheduled for execution. How would the treap look when the highest priority jobs have completed execution and therefore have quit the treap?
