Indicate the changes (using the shorthand representation) that you would need to make to the original KimTay Pet Supplies database design to support the following requirements. There is no relationship between customers and sales reps. When a customer places an order, any sales rep can process the order and create the invoice. On the invoice, you need to identify both the customer placing the order and the sales rep responsible for the invoice. Draw an E-R diagram for the new design.

Design a simple database for a hotel. This hotel may include guests, reservations, rooms, online rates, employees, services, and suppliers. You should draw the E-R diagram and design the relational schema.
Which of the following is a key part of physical design in an entity relationship model? O This model converts attributes into columns. O This model does not depend on the database management software or the hardware used to implement the model. O This model avoids any database model-specific details. This model resolves the many-to-many relationships to multiple one-to- many relationships.
When constructing a database, the designer must know what types of relationships exist between records in different data sets, such as one- to-many or many-to-many. Give three examples for each of these relationships.
Assume that you are the database developer for this task, complete the information-level design for the new database “Hostipal_Management” that satisfies the constraints and user view requirements given below. User view 1 requirement: The database should have information about Patients, Doctors, Appointments Bills and Payments. User view 2 requirements: Database system will store Patient’s details such as-Patient_ID, name, phone, email and home_address. Patients can make one or more appointments. However, one appointment is scheduled with only one patient. Patients can make several payments to the system, each payment belongs to only one patient. User view 3 requirements: Each doctor has an identification number and his/her name, telephone number, email and speciality should be recorded in the database. Examples for Doctor’s speciality - Cardiologist, Orthopaedics, Oncologists, Urologist, ..etc.(Note: It is a multi-valued attribute). User view 4 requirements: It is required to keep…

Topic: Database Design and Entity Relationship Diagrams Please convert the following diagram to Crow's Foot notation.
Your job as a database designer is to design a database with a schema that captures all the information that galleries need to maintain. Galleries keep information about artists, their names (which are unique), birthplaces, age, and style of art. For each piece of artwork, the artist, the year it was made, its unique title, its type of art (e.g., painting, photograph, sculpture), and its price must be stored. Pieces of artwork also classified into groups of various kinds, for example, portraits, still lives, works by Picasso, or works of the 19th century; a given piece may belong to more than one group. Each group is identified by a name (like those just given) that describes the group and property. Finally, galleries keep information about customers. For each customer, galleries keep that person’s unique ID, name, address, total amount of dollars spent in the gallery, and the artists and groups of art that the customer tends to like. Draw the ER diagram for the database.
