What is the primary benefit of using slots in the slotted page structure?

Review the following C++ class structure:class Employee {private: std::string name; int age;protected: double salary;public: Employee(const std::string& empName, int empAge, double empSalary) : name(empName), age(empAge), salary(empSalary) {} void displayInfo() const { std::cout

In some database management systems, free space metadata is stored in dedicated pages rather than alongside data within the same page. These dedicated pages track the amount of free space available in each data page across the entire database.What is a primary benefit of using dedicated free space metadata pages in a database management system?

Consider a C++ class Document which holds a text content using a std::string (which internally utilizes pointers to manage its data) and an integer representing the document length. The class is represented in-memory with pointers facilitating dynamic memory management, while it is serialized to disk without using pointers.Here’s an outline of the class and its serialization method:class Document {public: std::string text; int length; void serialize(std::ofstream& out) { length = text.length(); out.write(reinterpret_cast(&length), sizeof(length)); out.write(text.c_str(), text.length()); }};Which statement best captures the distinction between the in-memory and on-disk representations of the Document object regarding pointer usage?

Consider the behavior of variables in statically typed languages like C++ compared to dynamically typed languages like Python. Which of the following statements correctly reflects a fundamental difference between static and dynamic typing?

Consider the scenario where a database designer is structuring a relational database for a university. The database includes two tables: Students and Enrollments. The Students table has a primary key StudentID, and the Enrollments table lists the courses students are enrolled in, with CourseID and StudentID as its columns. The designer plans to enforce referential integrity between these tables.Which of the following implementations correctly utilizes primary and foreign key constraints to maintain database integrity and why?

Name the specific structure labeled A.

Name the epidermal layer labeled A.

A movie studio invited a representative audience to a preliminary screening of a movie. At the end of the movie the members of the audience were asked to answer a survey comparing the ending of the movie with two alternative endings. For simplicity let us denote the ending the audience saw by A, and the two alternative endings by B and C. Suppose that a member of the audience provided the following answers.Is A at least as good as B? NOIs A at least as good as C? YESIs B at least as good as A? YESIs B at least as good as C? YESIs C at least as good as A? YESIs C at least as good as B? NO

Consider the Utility function U(x,y)=x+ y2, where x denotes the amount of commodity 1 and y the amount of commodity 2. What is the value of utility for basket G in the following graph?
