The following problems expand on the tinyvideo case from chapter 7. to complete the following problems, it is necessary to have first completed the table creation and data entry requirements specified in problems 44 and 45 in chapter 7.35. alter the detailrental table to include a derived attribute named detail_dayslate to store integers up to 3 digits. the attribute should accept null values.36. alter the video table to include an attribute named vid_status to store character data up to 4 characters long. the attribute should not accept null values. the attribute should have a constraint to enforce the domain ("in", "out", and "lost") and have a default value of "in".37. update the vid_status attribute of the video table using a subquery to set the vid_status to "out" for all videos that have a null value in the detail_returndate attribute of the detailrental table.38. alter the price table to include an attribute named price_rentdays to store integers up to 2 digits. the attribute should not accept null values, and should have a default value of 3.39. update the price table to place the values shown in the following table in the price_rentdays attribute.

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
