Question
Chapter 13, Problem 7RQ
Program Plan Intro
Operational Data:
- Data quality is one of the key features of enterprise data management.
- The data obtained from the
operational system is low quality data because of the following reasons:- Obtaining the data from outside the organization.
- Redundant storage of data and inconsistent metadata.
- Problems while entering data due to poor interfaces, manual mistypes of data.
- The poor quality of the data is not recognized by the organization itself is an issue.
Data warehouse:
- Data warehouse contains the collection of data that are used for decision making and business intelligence.
- It is a unique kind of
database so it focuses on business intelligence, time variant data, and external data. - It is a subject-oriented, integrated, time-variant, and non-updateable data.

Modern life has been impacted immensely by computers. Computers have penetrated every aspect of oursociety, either for better or for worse. From supermarket scanners calculating our shopping transactionswhile keeping store inventory; robots that handle highly specialized tasks or even simple human tasks,computers do much more than just computing. But where did all this technology come from and whereis it heading? Does the future look promising or should we worry about computers taking over theworld? Or are they just a necessary evil? Provide three references with your answer.

- Objective: 1. Implement a custom Vector class in C++ that manages dynamic memory efficiently. 2. Demonstrate an understanding of the Big Five by managing deep copies, move semantics, and resource cleanup. 3. Explore the performance trade-offs between heap and stack allocation. Task Description: Part 1: Custom Vector Implementation 1. Create a Vector class that manages a dynamically allocated array. 。 Member Variables: ° T✶ data; // Dynamically allocated array for storage. std::size_t size; // Number of elements currently in the vector. std::size_t capacity; // Maximum number of elements before reallocation is required. 2. Implement the following core member functions: Default Constructor: Initialize an empty vector with no allocated storage. 。 Destructor: Free any dynamically allocated memory. 。 Copy Constructor: Perform a deep copy of the data array. 。 Copy Assignment Operator: Free existing resources and perform a deep copy. Move Constructor: Transfer ownership of the data array…arrow_forward2.68♦♦ Write code for a function with the following prototype: * Mask with least signficant n bits set to 1 * Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF * Assume 1 <= n <= w int lower_one_mask (int n); Your function should follow the bit-level integer coding rules Be careful of the case n = W.arrow_forwardHi-Volt Components You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys- tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not capable of handling EDI. Tasks 1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur- chasing system? 2. What terms or concepts describe the proposed computer-to-computer relationship between Hi-Voltage and Green Industries? why not? 3.
