Doctors have id. name. date of birth. and specialty. Patients have id. name, and date of birth. and address. Medicines have name. patent number, and milligrams We want to build A database that keeps track of the medicines prescribed by a doctor to patients The prescription process happens in a hospital. (a) Draw a complete Entity-Relationship diagram for the description above. You must include all the details, such as keys, weak entities (if any). cardinality constraints., etc Your diagram must use n-ary relationships You must use arrow notation Your diagram must avoid redundancy.
The conditions under which the database designer should employ supertype and subtype connections are outlined.
Design a database for a worldwide package delivery company (e.g., DHL or FedEx). The database must be able to keep track of customers who ship items and customers who receive items; some customers may do both. Each package must be identifiable and trackable, so the database must be able to store the location of the package and its history of locations. Locations include trucks, planes, airports, and warehouses. Your design should include an E-R diagram, a set of relational schemas, and a list of constraints, including primary-key and foreign-key constraints.
The conditions under which the database designer should employ supertype and subtype connections are outlined.
Please give a step-by-step answer. The ER Diagram must contain the ER-Diagram Symbols. Design an EER diagram for a Hospital Management System. The hospital wants to keep track of all their doctors, nurses, other staff, wards, patients and appointments. They have hired you to help them design the database for that purpose. You can design your EER as you wish, but it must satisfy the following constraints: a) there should be at least one disjoint-total specialization/generalization. b) There should be at least five regular/strong entities [excluding subclasses] c) There must be a weak entity d) There must be at least one M:N relationship. e) There must be at least one derived attribute.
When utilizing subtype associations, it is important to discuss the database table options that are available.Decide on the design you want to use and discuss the challenges that arise as a result of it.

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality. Swing Jazz Club The Swing Jazz Club teaches swing and jazz dancing and offers both private and group lessons. Swing Jazz charges $60 dollars per hour for a private lesson and $10 dollars per hour for a group lesson.…
San Diego Hospital Example ERD Problem Entity Relationship Diagramming is a "top down" user process. Take the following user provided information and draw the appropriate ERD. Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. Please use a drawing tool of some type to show the ERD diagram (Word, PowerPoint, and Visio all work well). I want you to get in the habit of drawing these with a computer instead of by hand, as this will be important as we get to more difficult…
Design an E-R diagram for a database for an airlines system. The database must keep track of customers and their reservations, flights and their status, seat assignments on individual flights and the schedule and routing of future flights. Apply all the database design constraints as much as possible.
Air West Airlines is a regional carrier that operates primarily in the southwestern United States. Draw an ER diagram to capture the following information in a database for the airline company. An airport is identified by a unique airport code and has a location which consists of (city, state), an elevation, and one or more phone numbers. An airport may have several flights to arrive at it and depart from it. A flight has a unique flight number, a base fare, and the number of seats. A flight can arrive at one or more airports and depart from one or more airports. For each arrival, the scheduled arrival time should be recorded. For each departure, the scheduled departure time should be recorded. Each flight has one or more staff members in its crew. Each staff member (who may be an attendant or a pilot, but not both) has a unique ID number, a name, and a hire date. A staff member may be assigned to several flights. Each flight attendant has a date for an advanced certification. Each…
