Each house is cleaned by one or more teams. A team goes out to a particular house on a certain day of the week. Each cleaning team has a team leader. Every cleaner eams R150 per day, except the team leader who earns a unique amount.

[Example: Mission: Impossible 2 is a 2000 American action spy film. This movie is sequel to 1996 film Mission: Impossible]. Movies are casted by actors where an actor has specific role [Example: MI 2 is starred (i.e., main character) by Tom Cruise] and an actor is identified by id, firstname, lastname and gender. A movie might have multiple genres [Example: MI 2 is characterized by three genres: Action | Adventure | Thriller]. A director who directs a movie is identified by id, firstname and lastname. We assume a movie can have at-most one director. [Example: John Woo is the director of MI 2 and he also directed well-known movies like 'A better tomorrow', 'Red Cliff', ‘Hard Boildeď’, ‘Face/Off'] Draw ER diagram with proper notation.
- 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…Could you perhaps elaborate on the Dataset object?Case Study:This case study considers the Credit approval dataset. This file concerns credit card applications.

Follow the same strategy used in chapter 7. please solve it using RStudio8. Matrix algebra is a theoretical way of manipulating a database. 9. The union of tables A and B is a table containing all rows that are in either table A or table B or in both table A and table B. 10. The intersection of two tables A and B is the set of all rows that are in table A but that are not in table B.

A user can request a quiz for the system. The system picks a set of questions from its database, and compose them together to make a quiz. It rates the user’s answers, and gives hints if the user requests it. In addition to users, we also have tutors who provide questions and hints. And also exam-inators who must certify questions to make sure they are not too trivial and those they are sensical. Make a use case diagram to model this system. Work out some of your use cases. Since we don’t have real stake holders here, you are free to fill in details you think is sensical for this example. Write a brief use case of Make quiz? Use case: Make quiz.
