Payroll Flowchart Analysis Discuss the risks depicted by the following payroll system flowchart. Describe the internal control improvements to the system that are needed to reduce these risks with specific explanations. An illustration of the above flowchart: It is represented in six columns and the column header reads: supervisor; payroll; data processing; accounts payable; cash disbursement; general ledger. In supervisor column, timekeeper enters into time cards and that leads to “Review Time cards and prepares Personnel Action Form” that further leads to two source documents “time cards, per action form.” Per action, form enters into prepare payroll in payroll column. Prepare payroll enters into paychecks and two source documents “payroll register, payroll register.” Payroll register leads to inverted triangle and payroll leads to A. Paycheck enters into review and distribute in supervisor column leads to paycheck and that further leads to employees. In data processing column,…

Using the following execution shown below, explain what is done in each of the ARIES recovery algorithm phases: LSN LOG 00 begin_checkpoint 10 end_checkpoint 20 update: T1 writes P1 30 update: T2 writes P2 40 update: T3 writes P3 50 T2 commit 60 update: T3 writes P2 70 T2 end 80 update: T1 writes P5 90 T3 abort CRASH, RESTART In addition to the execution shown here, the system crashes during recovery after writing two log records to stable storage and again after writing another two log records

A new application is being developed and will be using a database that includes a relation about items: Item (item_id:integer, item_name:string, color:string, price:real). Both the purchasing department in charge of obtaining raw material and the manufacturing department in charge of manufacturing the items can change the price of manufactured items according to changes that may happen in the raw material cost or production cost. The two departments use different transactions to update the price of items. The new application uses the following sequences of actions, listed in the order they are submitted to the DBMS: Sequence S1: T1:R(X), T2:W(X), T2:W(Y), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit Sequence S2: T1:R(X), T2:W(Y), T2:W(X), T3:W(Y), T1:W(Y), T1:Commit, T2:Commit, T3:Commit For each of the following concurrency control mechanisms, describe how they will handle each of the sequences (S1 & S2). Strict 2PL with timestamps used for deadlock prevention. Conservative…
