Chapter 21, Problem 1PE

Explanation of Solution

Benefits property:

If the query range contains only few tuples, then each query is executed quickly on a single disk. This allows the parallel execution of queries and leads to the reduced overhead on multiple disks.

Drawbacks:

If the query range has many tuples, every query required long time to execute as there is no parallelism within its execution. Some disks become hot-spots and thus increases the response time.

Refer to page 80 for problems on white-box testing. Instructions: • Perform control flow testing for the given program, drawing the control flow graph (CFG). • Design test cases to achieve statement, branch, and path coverage. • Justify the adequacy of your test cases using the CFG.

Refer to page 10 for problems on parsing. Instructions: • Design a top-down parser for the given grammar (e.g., recursive descent or LL(1)). • Compute the FIRST and FOLLOW sets and construct the parsing table if applicable. • Parse a sample input string and explain the derivation step-by-step.

Refer to page 20 for problems related to finite automata. Instructions: • Design a deterministic finite automaton (DFA) or nondeterministic finite automaton (NFA) for the given language. • Minimize the DFA and show all steps, including state merging. • Verify that the automaton accepts the correct language by testing with sample strings.
