How can the factor() function be used to map R onto a relational database management system (RDBMS)? It is used to map R's double values to the RDBMS's double values. It can be used to coerce the data into a categorical observation. It can be used to map logical data from R to a single character column in a database. It can be used to map character data to a fixed sized "CHARACTER" column.

Answer the following prompts 1The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team. 2The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Create a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the three fields. The CAR_ID and MAINTENANCE_TYPE_ID…

We need to create a database for the Circulation Department of a public library. The database will store information about the patrons, books, and circulation. It contains the following: 4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table. CHECKOUT table records the date of check-out, patron’s ID, the…

Suppose you are given the following business rules to form the basis for a database design. The database must enable the manager of a company dinner club to mail invitations to the club’s members, to plan the meals, to keep track of who attends the dinners, and so on. Each dinner serves many members, and each member may attend many dinners. A member receives many invitations, and each invitation is mailed to many members. A dinner is based on a single entree, but an entree may be used as the basis for many dinners. For example, a dinner may be composed of a fish entree, rice, and corn. Or the dinner may be composed of a fish entree, a baked potato, and string beans. A member may attend many dinners, and each dinner may be attended by many members. Because the manager is not a database expert, the first attempt at creating the database uses the structure shown in Table I: Table I Sample RESERVATION Records Attribute Name Sample Value Sample Value Sample Value…
