Design an ER schema for keeping track of information about votes taken in the U.S. House of Representatives during the current two-year congressional session. The database needs to keep track of each U.S. STATE's Name (e.g., 'Texas', 'New York', 'California') and include the Region of the state (whose domain is {'Northeast', 'Midwest', 'Southeast', 'Southwest', 'West'}). Each CONGRESS_PERSON in the House of Representatives is described by his or her Name, plus the District represented, the Start_date when the congressperson was first elected, and the political Party to which he or she belongs (whose domain is {'Republican', 'Democrat', 'Independent', 'Other'}). The database keeps track of each BILL (i.e., proposed law), including the Bill_name, the Date_of_vote on the bill, whether the bill Passed_or_failed (whose domain is {'Yes', 'No'}), and the Sponsor (the congressperson(s) who sponsored that is, proposed the bill). The database also keeps track of how each congressperson voted on each bill (domain of Vote attribute is {'Yes', 'No', 'Abstain', 'Absent'}). Draw an ER schema diagram for this application. State clearly any assumptions you make.

An insurance company needs to store their salespeople’s information who are selling their insurance policies. They already have a database with multiple tables, one of the tables (Salesperson) stores information about each salesperson along with the bonus percent they receive, based on the city where the insurance is sold. The table has the following fields: Salesperson(spID, spName, spBirthDate,spCitySelling, bonusPercent) spID: Unique identification number of the salesperson. spName: Full name of the salesperson. spBirthDate: Birthdate of the salesperson. spCitySelling: The city in which the salesperson is selling the insurance. bonusPercent: The bonus percent received by the salesperson based on the city in which he/she sells the insurance.

For example, all of the salespeople who sells insurance in…

calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
Software Engineering The recruitment agency TEMPO proposes internship employees for enterprises for a periodof time. An internship employee is a temporary employee that will be recruited for a periodof time. You must develop a database application in order to satisfy these specifications: The enterprises (id, name, address and phone number) define the posts for which theyneed one or many employees. A post is defined with a label, a daily remuneration, thestart date, the end date and the number of employees for this post. A post needseventually diploma(s) and a list of many skills. An internship employee is described by a ssn, first name, last name, an address, aphone number, his/her diplomas (we store for each diploma the year when it isobtained) and his/her skills. An employee could be recruited for one or many posts. This recruitment of anemployee for a given post is validated by a chief (ssn, first name, last name, address)designated by the enterprise. This chief is unique to an…

“Martial Arts R Us” (MARU) needs a database. MARU is a martial arts school with hundreds of students. The database must keep track of all the classes that are offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance. Students are given a student number when they join the school. The number is stored along with their name, date of birth, and the date they joined the school. All instructors are also students, but clearly not all students are instructors. In addition to the normal student information, for all instructors, the date that they start working as an instructor must be recorded along with their instructor status (compensated or volunteer). An instructor may be assigned to teach any number of classes, but each class has one and only one assigned instructor. Some instructors, especially volunteer instructors, may not be assigned to any class. A class is offered for a…

Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher. Abook is identified by its ISBN, and other attributes are title, price, and number of pages. Each book iswritten by one or more authors; an author writes one or more books, potentially for differentpublishers. Each author is uniquely described by an author ID, and we know each author's name andaddress. Each author is paid a certain royalty rate on each book he or she authors, which potentiallyvaries for each book and for each author. An author receives a separate royalty check for each book heor she writes. Each check is identified by its check number, and we also keep track of the date andamount of each check.TasksDesign a SQL database using the above US superstore sales data set.1.Use Visual Paradigm to draw conceptual diagram2.Use Visual Paradigm todraw ERD
