- Consider the database schema below for cities in countries. A country have many cities, and the same city name can be found in different countries. Country (ID: integer, Name: String (unique)) City (serialNo: integer (unique, not null), CountryID: Integer, CityName: String, Population: integer) A city can have unknown CityName? No, violates domain constraints. Yes. No, violates entity Integrity constraint No, violates key constraint. No, violates referential integrity constraint.Subject:database administration and management question: select a database like customer tb,employee tb and customer tb make a set of predicate generate minterm predicate and fragments and make a correctness rule of fragmentationLet us consider the following relational database. Students(stuID, lastName, firstName, major, gpa) Faculty(facID, name, deptName, rank) Classes(classNhmber, facID, schedule, room) Enrolls(stuID, classNumber, grade) The primary keys are underlined. The referential integrity constraints are as follows: The column facID of relation Classes that references table Faculty, The column of stuID of relation Enrolls that references table Students, and The column classNumber of relation Enrolls that references table Classes. The following SQL statement is intended to define the table Students. However, this statement does not work correctly. CREAT TABLE Students( lastName VARCHAR(20), firstName VARCHAR(20), major VARCHAR(40) gpa DECIMAL(3,2), PRIMARY KEY(stuID)); However, this statement does not work correctly. Briefly explain why and list the corrected SQL statement.

- Computer Science When it comes to maintainable database persistence, a common code smell is... a. not using Future callbacks for the database-specific code found throughout our application b. not closing the database after each transaction c. using lower-case String literals for our SQL statements d. placing database-specific code in multiple places throughout our application codebaseCreate a Crow's Foot ERD for each of the following descriptions. (Note that the word many merely means more than one in the database modeling environment.)a. Each of the MegaCo Corporation's divisions is composed of many departments. Each department has many employees assigned to it, but each employee works for only one department. Each department is managed by one employee, and each of those managers can manage only one department at a time.b. During some period of time, a customer can download many ebooks from BooksOnline. Each of the ebooks can be downloaded by many customers during that period of time.c. An airliner can be assigned to fly many flights, but each flight is flown by only one airliner.d. The KwikTite Corporation operates many factories. Each factory is located in a region, and each region can be "home" to many of KwikTite's factories. Each factory has many employees, but each employee is employed by only one factory.In which of the following situations, the decision is NOT made based on efficiency vs. modifiability design trade-off? A when choosing between vertical or horizontal mapping for relational database design B when choosing between repository or MVC architectural pattern C when choosing between opaque or transparent layering D when deciding whether to use façade pattern E when determining the visibility of a class attribute that is heavily accessed by other classes
- What are constraints in database. Provide a real-world example. What are the consequences If we do not implement constraints? Describe the disadvantages of database system. What is a multivalued attribute? Provide a real-world example of multivalued attribute.Defineanomaly? Exists a database where the three anomalies were discovered? Give a response to any anomalies that could be caused by resolving the issues?. For each item below, specify whether the statement is true (T) or false (F). Each Database Management System (DBMS) is based on a Data Model. Database Users may desire to perform conflicting operations at the same time. For example, in an Airline Reservation System, two on-line users may see the last empty seat while trying to reserve a seat on a flight. Concurrency features of a DBMS prevents them from reserving the same seat, therefore avoiding inconsistent database states. In the Entity-Relationship Model (E-R), an Attribute maps an entity to another entity (or a set of entities). A Relationship, on the other hand, maps an entity to a primitive value. Specialization ISA is the result of taking the union of two or more lower-level entity sets to produce a higher-level entity set. It emphasizes the similarity. In the Network Data Model, relationships between record types are implemented by means of Link Types. Since…
