Entity-Relationship Diagram (ERD)
An ERD visually represents the relationships between entities in a database. Here's what you need:
Entities:
Product: Represents items sold by the coffee shop.
Transaction: Represents a sale event.
Payment: Represents the payment method used for transactions.
BeanCard: Represents the loyalty or prepaid cards customers can use.
Attributes:
Product: Product ID, Name, Category (Beverages, Bakery goods), Price.
Transaction: Transaction ID, Date, Total Amount.
Payment: Payment ID, Type (Cash, Credit, BeanCard), Amount.
BeanCard: Card ID, Customer ID, Balance.
Relationships:
Products to Transactions: A transaction can include multiple products (many-to-many).
Transactions to Payment: A transaction is completed with a single payment method (one-to-one).
BeanCard to Payment: A BeanCard can be used for many payments…
Computer Science
After completing a course in database management, you have been hired as a summer intern by Mountain View Community Hospital. Your first assignment is to work as part of a team of three people to develop a high-level E-R diagram for the hospital. You conduct interviews with a number of hospital administrators and staff to identify the key entity types for the hospital. As a result, your team has identified the following entity types:
• CARE CENTER—a treatment center within the hospital. Examples of care centers are maternity, emergency care, or multiple sclerosis center. Each care center has a care center ID (identifier) and a care center name.
• PATIENT—a person who is either admitted to the hospital or is registered as an outpatient. Each patient has an identifier, the medical record number (MRN), and a name. The hospital also records the date of first contact with the hospital (Contact Date)
• PHYSICIAN—a member of the hospital medical staff who may admit patients…
ERD and Keys
A hotel has many rooms. A guest can make a reservation for one room or multiple rooms. A reservation is associated with only one guest. Draw an ERD with the relationships and resolve any many to many relationships. Create an ID for each entity you create (for example RoomID, GuestID, Reservation ID) as the Primary Key. Identify any foreign keys in each entity where appropriate.

- 1. Create an entity relationship diagram for the conceptual design using UML notation. The diagram can be created by hand or via some modeling tool. 2. Create a data dictionary for the entities, relationships and attributes. Make your best guess for representing the attributes. Schema 3 You have been hired by the Snowbird ski mountain resort to build a database for their data. The resort has ski mountain peaks, chair lifts, trails, stores and restaurants. For each mountain peak, you track the name, the elevation and its latitude and longitude. Each peak name is unique. The names of the mountain peaks are: Mount Superior, Mount Baldy, Twin Peaks and Hidden Peak. For each chair lift, you track a unique name, the vertical rise, the travel time, the number of people per chair (ranging from 2 to 4) , and its closing time. For each trail, you track its unique name, its elevation, its length, and the typical time it takes to complete. Each ski trail is classified by its level of…arrow_forwardManufacturer A manufacturing company produces products. The following product information is stored: product name, product ID and quantity on hand. These products are made up of many components. Each component can be supplied by one or more suppliers. The following component information is kept: component ID, name, description, suppliers who supply them, and products in which they are used. Create an ERD to show how you would track this information. Show entity names, primary keys, attributes for each entity, relationships between the entities and cardinality. Assumptions A supplier can exist without providing components. A component does not have to be associated with a supplier. A component does not have to be associated with a product. Not all components are used in products. A product cannot exist without components.arrow_forwardERD Diagram LucidChart Please be sure to accurately draw each entity, connecting lines, cardinality, actions (relationships), and attributes. Please be sure to properly label – if appropriate – your attributes. Please be sure to designate a primary key and foreign key(s) for each attribute. Please sure to properly label your associative entity – if appropriate. Please be sure to add to your diagram entities “user defined” primary key fields and appropriate foreign key fields Red Light Minor Emergency Clinic located in Wichita Falls, Texas is a 24-hour clinic that provides patients with minor emergency medical care. The clinic would like you to draw and ERD diagram that depicts their customer care process.

- ENHANCE ENTITY RELATIOSHIP DIAGRAM The entity type PERSON has the following attributes: SSN, name, address (City/State/Zip), date of birth, age, and contact number. The entity also has the three subtypes: CAMPER, BIKER, AND RUNNER. Draw a separate diagram segment for each of the following situations: 1. At a given time, a person must be exactly one of three subtypes. 2. A person may or may not be one of these subtypes. However, a person who is one of these subtypes cannot at the same time be one of the other subtypes. 3. A person may or may not be the one of these subtypes. On the other hand, a person may be any two (or even three) of these subtypes at the same time. 4. At a given time, a person must be at least one of these subtypes.arrow_forwardWhich of the following is a key part of conceptual design in an entity relationship model? This model uses column names instead of attributes. In this model, the characteristics such as location, path, and format are described. This model converts entities into tables. In this model, no primary keys are specified in the entities.arrow_forward______ represent real-world associations between entities. Entities Attribute Relationships Primary Keyarrow_forward

Faculty should have an attribute identifying their rank. Properly identify all of the primary keys (use solid underlines). Create an entity relationship diagram (ERD) from the entities. You may use SmartDraw, Visio, Erwin, or even Word to draw the diagram. Take a screenshot (no need if you use Word), and insert it into the Word document. Part 2 Use Microsoft Access to implement the database that you designed in Part 1, and include the following: Create the Student, Faculty, and Course tables in Access.
