3- United Broke Artists (UBA) is a broker for not-so-famous artists. UBA maintains a small database
to track painters, paintings, and galleries. A painting is created by a particular artist and then
exhibited in a particular gallery. A gallery can exhibit many paintings, but each painting can be
exhibited in only one gallery. Similarly, a painting is created by a single painter, but each painter
can create many paintings. Using PAINTER, PAINTING, and GALLERY, in terms of a relational
database:
a. What tables would you create, and what would the table components be?
b. How might the (independent) tables be related to one another?
C.
Create a basic ERD.
d. Convert the ERD above to a UML Class Diagram.
United Broke Artists (UBA) is a broker for not-so-famous painters. UBA maintains a small network database to track painters, paintings, and galleries. A painting is painted by a particular artist, and that painting is exhibited in a particular gallery. A gallery can exhibit many paintings, but each painting can be exhibited in only one gallery. Similarly, a painting is painted by a single painter, but each painter can paint many paintings. Using PAINTER, PAINTING, and GALLERY, in terms of a relational database:
a.What tables would you create, and what would the table components be?
b.How might the (independent) tables be related to one another?
2. Using the ERD from Problem 1, create the relational schema. (Create an appropriate collection of attributes for each of the entities. Make sure you use the appropriate naming conventions to name the attributes.)
To access a database, we need to open a connection to it first and close it once our job is done. Connecting to a database depends on the type of the target database and the database management system (DBMS). For example, connecting to a SQL Server database is different from connecting to an Oracle database. But both these connections have a few things in common: •They have a connection string •They can be opened•They can be closed•They may have a timeout attribute (so if the connection could not be opened within the timeout, an exception will be thrown).Your job is to represent these commonalities in a base class called DbConnection. This class should have two properties: ConnectionString : stringTimeout : TimeSpanA DbConnection will not be in a valid state if it doesn’t have a connection string. So you need to pass a connection string in the constructor of this class. Also, take into account the scenarios where null or an empty string is sent as the connection string. Make sure to…

- PrimeVideo is a startup company providing concierge DVD kiosk service in upscale neighborhoods. PrimeVideo can own several copies (VIDEO) of each movie (MOVIE). For example, a kiosk may have 10 copies of the movie Twist in the Wind. In the database, Twist in the Wind would be one MOVIE, and each copy would be a VIDEO. A rental transaction (RENTAL) involves one or more videos being rented to a member (MEMBERSHIP). A video can be rented many times over its lifetime; therefore, there is an M:N relationship between RENTAL and VIDEO. DETAILRENTAL is the bridge table to resolve this relationship. The complete ERD is provided in the figure. Write the SQL code to create the table structures for the entities shown in the figure. The structures should contain the attributes specified in the ERD. Use data types (and lengths, if applicable) that are appropriate for the data that will need to be stored in each attribute. Enforce primary key and foreign key constraints as indicated by the ERD.

The database also stores the make, model and year of the truck. Drivers are identified by SSN (Social Security Number) which is 9 characters long. The database also stores first name, last name and address of each driver. Trips are also stored in the database. Each trip has one truck making the trip, one driver, date of trip, and total miles covered. Any driver can be assigned to any truck. Write the tables and attributes you would need to have in your database to track this information.

The bookstore carries 13,000 titles, but you plan to sample only 200 books. You will select a sample of 200 books, record the price of each book, and use the average of the 200 books to estimate the average price of the 13,000 titles in the bookstore. Assume that the bookstore can give you access to a database that lists all 13,000 titles that it carries. 1. How would you collect a cluster sample from the scenario above? 2. How would you collect a simple random sample of books? 3. Discuss one possible way that you could end up with a biased sample when conducting this study (hint: be sure to discuss how the sample could be gathered and the type of bias that could occur).arrow_forward
- Suppose you are asked to design a club database system based on the following information. Each student has a unique student id, a name, and an email; each club has a unique club id, a name, a contact telephone number, and has exactly one student as its president. Each student can serve as a president in at most one of the clubs, although he/she can be the members of several clubs. Clubs organize activities and students can participate in any of them. Each activity is described by a unique activity id, a place, a date, a time and those clubs that organize it.
