Consider relations a and b. relation a represents the entity on the ""one side"" of a one-to-many relationship; relation b represents the entity on the ""many side"" of the one-to-many relationship. the delete rule between relations a and b is restrict. if an attempt is made to delete a record in relation a and its primary key value appears as a foreign key value in one or more records of relation b

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?

Write a program that reads a set of floating-point values. ask the user to enter the values, then print • the average of the values. • the smallest of the values. • the largest of the values. • the range, that is the difference between the smallest and largest. of course, you may only prompt for the values once.
