Chapter 1, Problem 1.31RQ
Program Plan Intro
Database is a container or structure that is used to store or hold the data. It is a collection of organized data and it can be used to keep track of things.
Complexity in a database:
- DBMS (Database Management System) is a large, complex program or software that is used to manage and administer the stored databases and it is a computer based system to keep records.
- Query language such as SQL is used along with DBMS to interact with the database.
- It solves all the problems related to database and fulfils the requirements of the user.
- All these performance of DBMS makes it very complex software. Not understanding the functionalities of DBMS may cause database failure or data loss.

- 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.arrow_forwardObjective: 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_forward
- Hi-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. Would Hi-Voltage's proposed new system be a transaction processing system? Why or 4. Before Hi-Voltage makes a final decision, should the company consider an ERP system?

Two of the refernces can be from an article and the other two from websites.arrow_forwardAssume that a string of name & surname is saved in S. The alphabetical characters in S can be in lowercase and/or uppercase letters. Name and surname are assumed to be separated by a space character and the string ends with a full stop "." character. Write an assembly language program that will copy the name to NAME in lowercase and the surname to SNAME in uppercase letters. Assume that name and/or surname cannot exceed 20 characters. The program should be general and work with every possible string with name & surname. However, you can consider the data segment definition given below in your program. .DATA S DB 'Mahmoud Obaid." NAME DB 20 DUP(?) SNAME DB 20 DUP(?) Hint: Uppercase characters are ordered between 'A' (41H) and 'Z' (5AH) and lowercase characters are ordered between 'a' (61H) and 'z' (7AH) in the in the ASCII Code table. For lowercase letters, bit 5 (d5) of the ASCII code is 1 where for uppercase letters it is 0.
