Course: Database Systems: Design and Application Web Shop scenario: A supplier (Supp-#) processes many purchase orders (PO-#) and sells a number of products (Prod-#). A product is sold by only one supplier. Each of the purchase orders that a supplier may process includes several products. The relationship between order and product is defined as "Line Item". A customer (Cust-#) may place one or more purchase orders. A purchase order may be placed by only one customer. Assignment requirements: Answer the following questions using above scenario: Identify the entities and attributes that required to draw the ER diagram. Integrate the entities with appropriate relationship and design the unified ER model.

Give Authentic and relevant answer. DATABASE SYSTEMS Construct an Enhanced ERD along with Possible entity clusters of the given below system. This describes the business process to publish an academic paper. The author submits a paper to an editor of a journal. The editor first checks whether the paper fit the theme of the journal. If not, the editor rejects the paper. Otherwise, the editor assigns the paper to a number of reviewers. The reviewers review the paper, and write a review. The review is sent to the editor. The editor then assesses the quality of the paper with the help of reviewers’ comments. If the quality is good, the paper will be accepted, and the author notified. Furthermore, the paper is forwarded to the publisher for publication. If the quality is bad, the editor rejects the paper.

A satisficing model is one that will find a good problem solution, although not necessarily the best problem solution. True or False?
Every company having customers maintains customer accounts and supports a complete life cycle of the account from its creation until it is closed. There are differences in what are the stages (states) in the account's life cycle, and what are conditions or events causing account to change its state.For the user account to be created, it has to meet some initial requirements. For example, user id (used as a login name) must be unique, at least for the existing accounts. After account was created, it might need to be verified. Verification depends on the company and could include e-mail, phone, and/or address verification. If account was not verified during some predefined period of time, that account could be moved to the suspended accounts. New, active, or suspended accounts could be cancelled at any time by client's request. Note, the precondition for this usually includes payment of any outstanding balances, and might require some separate account state or substate to handle this…
Ball at the wallcontext In a ball-at-the-wall game, children in the schoolyard must throw balls at the school wall to reach lines placed at certain heights. You want to predict how high the ball will hit the wall based on the parameters of the throw. Constraints and information The children are all placed behind a line drawn on the floor, at a known horizontal distance ? from the wall;The initial height at which the ball leaves the child's hand is known;The speed and angle of the throw are known; Modelization Creates a model to determine how high the ball will hit the wall based on the children's distance from the wall and the height, speed and angle of the ball as it leaves the child's hand . Then test your model with the following parameters Distance between the wall and the child: 3.9?; Height of the ball when it leaves the child's hand: 1.05?; Throw Speed: 14.1?/?; Throw angle: 51∘
Activity: Interaction Models Consider the university system. Departments offer courses. Professors teach courses. Students can declare majors and are admitted to university departments if they meet minimum requirements. Students and professors have schedules based on courses they take/teach. Courses have rosters, scheduled times, and instructors. Courses may get full. Students can request to sign up for courses, and if the course is not full and they meet pre-requisites, the course is added to their schedule and the course will have them as a student in that course. Students can also drop courses. Students should be informed of the consequences such as change of status from full-time to part-time, loss of scholarships, and delays in graduation. Perform the following: 1. Create a use-case diagram for this university. Make your use-case diagram as complete as you can. 2. Pick two use cases from your use case diagram, CourseAdd and CourseDrop, and describe these use cases in the standard…
