Solved in 3 steps
- If any of the following choices are applicable, please tick them. This model includes entities like as customers and accounts; employees; checks; and transactions. Using recursive relationships correctly, which of the following is the proper choice?(A) Checks drawn on a checking or savings account are referred to as "checks."Bank transactions that are both credit and debit belong to the same account, as do checks, and so do employees and their managers.With examples, explain the distinctions between is-a relationship and has-a relationship.In computer programming, selection structures are essential, but they have their limits. The same repetitive procedure is required for many consumers, online clients, and other forms of transactions across all applications. Does each of these occupations have its own set of rules? What sets these structures apart from the rest?
- A/An ___________ is an association among entities. Write the letter of the correct answer in the blank. a. Object-based logical model b. Relationship c. Data modelStore the following fields for a library database: AuthorCode, AuthorName, BookTitle, BorrowerAddress, BorrowerName, BorrowerCardNumber, CopiesOfBook, ISBN (International Standard Book Number), LoanDate, PublisherCode, PublisherName, and PublisherAddress. A one-to-many relationship exists between publishers and books. Many-to-many relationships exist between authors and books and between borrowers and books. Draw the Crow’s Food entity-relationship diagram for the library database.Draw the relationships and entities model for each of the following: * in the traditional way* for example: see the pic??. In the database of the library, the author can author more than one book, and the book can be subscribed toWritten by more than one author
- A _____ relationship exists when an association is maintained within three entities. strong binary ternary unary1. What technique is used to model the situation that Student may have multiple addresses? A) Associative Entity (gerund)B) Weak entitiesC) Super/sub typesD) Recursive relationships 2.There is m:m relationship between students and classes. Which technique is used forrepresenting the student grade? A) Associative Entity (gerund)B) Weak entitiesC) Super/sub typesD) Recursive relationships 3. An associative Entity (gerund) may be used whenever there are data that depends on twoentities even when their relationship is 1:m. True or FalseA) TrueB) False 4. (check all that apply) When do you use recursive relationships?A) the relationship between employees and their supervisorsB) the relationship between employees and their dependentsC) the relationship between employees and their departmentsD) the relationship between employees and their team membersE) the relationship between employees and their job assignments 5. How is a gerund converted into a relational model?A) ignore the gerund in the…On three paragraphs, clarify the distinctions between variables and attributes.
- Programming cannot exist without the use of selection structures, however these structures are not without flaws. Because of the large number of users, online customers, and diverse types of transactions, each application must follow the same iterative method. Are those working in these fields required to comply by a certain code of ethics? What exactly is it that sets these constructions apart from others?76. Aggregation is which of the following? a. Expresses a part-of relationship and is a stronger form of an association relationship. b. Expresses a part-of relationship and is a weaker form of an association relationship. c. Expresses an is-a relationship and is a stronger form of an association relationship. d. Expresses an is-a relationship and is a weaker form of an association relationship.Using a graphics program, develop an entity-relationship diagram for a database application for an Internet bookstore where students buy textbooks from a salesperson and receive invoices for their purchases. Use Figure 5.5 as a guide.
