Use ER Assistant to draw your diagram.   Draw a generalization hierarchy containing Employee, Administrator, and Faculty entities.  The Employee entity is the supertype, and the Administrator and Faculty entities are the subtypes.  The Employee entity has attributes as follows:  EmpNo (primary key), EmpName, and EmpAddress.  The Administrator entity has attributes as follows: AdmTitle,  AdmContractLength The Faculty entity has attributes as follows:  FacTenure, FacRank The generalization hierarchy should be disjoint but not complete.

Design the UML class diagram to support the system below and upload a picture of your diagram. Used Class Material Website: You are designing a website where students can resale their used material for a course.   A course may have multiple sections.  The course material is specific to each section of a class. Not all course may require class materials, but they may require many of them. A student can have many used materials for sale. The class material can be either:   ·       Textbook: which has a price(mandatory), title(mandatory), authors(optional), edition(optional) ·       Software: which has a price(mandatory), title(mandatory), publisher(optional), and also its operating system (mandatory) ·       Equipment:  which has a price(mandatory), title(mandatory), description(mandatory) All class material can be either available or sold. Do a class diagram with: 1.     all the classes , 2.     their associations  3.     their multiplicity .    4.     For each classes, where are the…

Draw UML class diagram according to descriptions given below. Please include appropriate labeling and multiplicity in your diagrams. You do not need to include the attributes and operations for the classes. A Rectangle object is composed of exactly four Line objects A Customer object is able to initiate zero or more Transaction A Student Object must enrolls in at least one, at most five Subject A Mouse object is kind of a Rodent A Rodent object is a kind of Mammal Object.

Q1. Draw an E-R Diagram for the following situation. At the university system each STUDENT must be assigned an ADVISOR who counsels students about degree requirements and helps students register for classes (COURSE). Each student must register (REGISTRATION) for classes with the help of an advisor, but if the student's assigned advisor is not available, the students may register with any advisor, We must keep track of students, the assigned advisor for each, and the name of the advisor with whom the students registered for the current term. Tips: Attributes of STUDENT include Student ID (the identifier), Name, and Major. Attributes of ADVISOR include Advisor ID (the identifier), Name, and Department. Attributes of COURSE include Course ID (the identifier), Title, and Credits. Attributes of REGISTRATION include Semester, and Year. Based on your background, think of logical and standard relationships between the given entities.

b) An ER/EER diagram modeling your database (use appropriate symbols, and don’t forgetassociative entities where appropriate). This will be based on the business rules you created, somake sure you’ve written clear rules! (30 points)• Feel free to use an appropriate design tool you would like for your ER diagram (e.g.http://draw.io), or do it by hand and scan it in; just make sure it is legible and that itfollows the notation/style taught in class. Do NOT use other styles, such as “Visio”notation that includes PK/FK.c) A list of normalized relations (using the notation from class) that is based on your ER diagram.Be sure to include foreign keys, etc. (30 points)

What is NOT another name for an associative entity?     Linking table Bridge entity Composite entity Strong entity

b. Draw an Entity Relationship diagram from each of the following descriptions. Include the attributes, primary keys (underlines) and the relationships in the diagram (like relationship in Access). i. Each of the department has many employees assigned to it, but each employee works for only one department. if. A customer can rent many videotapes from the video store. Each of the videotapes can be rented to many customers.

Let's break down the information into entities, attributes, and relationships: Entities: 1. Ship - ShipID (Primary Key) - ShipName - ShipType 2. Captain - CaptainID (Primary Key) - CaptainName - CaptainLicense 3. ShipmentTrip - TripID (Primary Key) - DeparturePort - ArrivalPort - RouteDetails 4. ShipmentManifest - ManifestID (Primary Key) - Date - GoodsList 5. Goods - GoodsID (Primary Key) - GoodsName - GoodsType (BM or LM) 6. Port - PortID (Primary Key) - Street - City - State - PostalCode - Country Relationships: - Ship to ShipmentTrip (Many-to-Many): - Ship can participate in multiple ShipmentTrips, and a ShipmentTrip can involve multiple Ships. Create a junction table `Ship_ShipmentTrip` with attributes `ShipID` and `TripID`. - Captain to ShipmentTrip (Many-to-Many): - A Captain can be assigned to multiple ShipmentTrips, and a ShipmentTrip can have multiple Captains. Create a junction table `Captain_ShipmentTrip` with attributes `CaptainID` and `TripID`. - Captain to Ship…

It's not immediately clear what distinguishes a weak entity from a strong entity that requires a relationship with another entity.

Domain Model Class Diagram LAB 6: Academic Scenario With the following information given below, design a domain model class diagram. A university has only full-time and part-time instructors. The details of an instructor include name, address, email, and number. The students in the university can enroll in a seminar and the details to be stored for each student include name, student number, and email. Each seminar consists of seminar name and seminar code. Full-time instructors are responsible for taking the seminars. Each seminar can be taken by at least one and at most two instructors. Part-time instructors can teach courses as well as full-time instructors. Each course consists of a name and course code. Students can register for a maximum of five courses per semester. A course can either be a university elective or an area elective. The availability of an area elective course depends on the number of available students for that course. A student can either be a bachelor, master's,…
