Given the data requirements, design an Entity-Relationship diagram for the following statements. Show all entities along with minimum and maximum cardinalities. State any necessary assumption, if required. Note: You can upload the ERD image that can be either drawn by hand or online using any tool. Make sure to upload the image within the quiz duration. No extra time will be given to upload the image. Statements 1. A grade need not be associated with any staff members, or it can be associated with an many staff members; a staff member must be associated with one or more grades 2. A customer can place only one order and a given order can be placed by at most one customer

Draw an ER diagram for the following scenario- • An instructor has an ID, a name, and a phone number. An instructor teaches a course • A course has a code, course name, credits, and an instructor. Each course uses a textbook. • A textbook has ISBN, name, publisher, editor, and authors. Your ER diagram should have entities, attributes, composite attribute, multivalued attribute, key attributes, binary relationships, and a total participation. Explain your rationale behind each design choice. Please draw the ER diagram on paper showing all seperate parts for each instructor, course and textbook.

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.
Use ER Assistant to draw your diagram. Draw an ER diagram that includes entities for Clients, Contracts, and Contacts. Clients have the following attributes: ClientID (primary key), ClientName, ClientAddress. Contracts have the following attributes: ContractID (primary key), ContractType, LicenseFee. Contacts have the following attributes: ContactID (primary key), ContactName, ContactAddress. Draw a relationship between Clients and Contracts such that a Client can be assigned to many contracts, but it can also exist without having any contracts at all in the database. Conversely, a contract can be assigned to only one client but must be assigned to a client in order to exist. Name your relationship “Signs”. Draw a relationship between Clients and Contacts such that a client must be assigned to one and only one contact. A contact can exist in the database without being assigned to a client, but a contact can be assigned to more than one client. Name your relationship “Has”.
