Chapter 9, Problem 9.39PAE
You are to construct a star schema for Simplified Automobile Insurance Company (for a more realistic example, Kimball, 1996b). The relevant dimensions, dimension attributes, and dimension sizes are as follows:
| InsuredParty |
Attributes: InsuredPartylD and Name. There is an average of two insured parties for each policy and covered item. |
| Coverageltem |
Attributes: CoverageKey and Description. There is an average of 10 covered items per policy |
| Agent |
Attributes: AgentID and AgentName. There is one agent for each policy and covered item. |
| Policy |
Attributes: PolicylD and Type. The company has approximately 1 million policies at the present time. |
| Period |
Attributes: DateKey and FiscalPeriod. |
Facts to be recorded for each combination of these dimensions are PolicyPremium, Deductible, and NumberOfTransactions.
- Design a star schema for this problem. See Figure 9-10 for the format you should follow.
- Estimate the number of rows in the fact table, using the assumptions stated previously.
- Estimate the total size of the fact table (in bytes), assuming an average of 10 bytes per field.

He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

- In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
