Which of the following is a key part of conceptual design in an entity relationship model? This model resolves the many-to-many relationships to multiple one-to-many relationships. This model adds all of the attributes for each entity. This model converts attributes into columns. This model does not depend on the database management software or the hardware used to implement the model.
Kindly find attached. Normalize the relations into first, second, and third normal form. First, describe the changes required to your relations to meet the standard of first 1NF and then 2NF and lastly 3NF. Then, you should provide an Entity Relationship diagram that is in 3NF. All attributes, entities, keys, and relationships should be included and labeled. Hint: (Attached)Remember that in the hospital software system, the “Patient” relation includes “medicines” attribute and the “Appointment” relation includes “allergies” attribute. Allergies describe a list of any known allergies and medicines describe a list of medicines prescribed for a patient. It should define or describe the changes required to get the relations into the 1st normal form. It should define or describe the changes required to get the relations into the 2nd normal form. It should include an Entity Relationship diagram in the 3rd normal form. The primary and foreign keys, at a minimum, are defined for each…
Create a database Entity and Relationship Diagram (ERD) for the following applicationThe Application idea: It is a mobile application called (Khair) to help people. This assistance is moral, material. This assistance is also provided by good people in our community. Example to understand the Application idea more: For example, a person urgently needs a medical chair or bed and does not have the ability to purchase what he needs. The medical chair or bed is requested through the application, and whoever has what he requests initiates the request through the application’s messages and determines the meeting place. Application models (page): Login included: login registration login included: user name password New registration included: name E-mail Password phone number date National Identification Number Home page included: Request - applicant name - address - send message Messages list form included: list of users Messager Personal information form: It contains a list of the user's…
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.
Question: Consider a relation named as BOOK that contains data about the books in a library. BOOK relation was initially created with the attributes BookID (an id that library assigns), ISBN, CopyNr (used to differentiate copies of the same book), Title, PublYear, Author, and AuthorBornYear. Primary key: BookID, CopyNr and Author Candidate key: ISBN, CopyNr and Author Below you see dependencies of attributes: Dependency 1 (D1): ISBN, Title, PublYear, AuthorBornYear were dependent on BookID, CopyNr, and Author Dependency 2 (D2): Title and PublYear were dependent on BookID, CopyNr Dependency 3 (D3): AuthorBornYear was dependent on Author First determine which normal form (1NF, 2NF, 3NF, or BCNF) the above relation is, and why. Then, if necessary, convert the above relation to the highest normal form (BCNF). Write any assumptions that you make Subject: MYSQL
Instructions: Create a complete ERD in Crow's Foot notation that can be implemented in the relational model using the descriptions below. The attributes required: Activity's ID, Activity's Title, Activity's description, Child's ID, Child's firstname and lastname, Child's Birthday, Parent's ID, Parent's number, Parent's address. The business rules are: An activity may or may not have a child signed up An activity may have many children signed up A child must have an activity A child may have many activities A child must have a parent A parent must have a child A child may have many parents A parent may have many children To submit: Write your answer in a clean sheet of paper and upload a picture of it to dropbox
The following ERD refers to an borrow system of a library. Member can borrow different books, which were written by different authors and published by different publishers. A writer can be contracted to one or more publishers. Each member can have different borrows with different books to different expiring dates.a)Give two Attributes for each entity. Draw them directly into the ER-diagram. b)Give a primary key for each entity. Draw it directly into the ER-diagram. c)Create the SQL statement for implementing the table for one of the entities of the up standing ERD
Which of the following statements are correct about EER model for this requirement? Book, Periodical, DVD, ReferenceItem, BorrowingItem, RegisteredUser, and TemporaryUser are set as entities. RegisteredUser and TemporaryUser can be generalized into a User entity. The specialization/generalization hierarchy for users is overlapping for disjoint constraint. Book, Periodicals, DVD, ReferenceItem, and BorrowingItem can be generalized into an Item entity
Draw an ERD that shows the entities, attributes, primary key(s), foreign key(s), and relationships. Each relationship must be labeled. List all identifying relationships (if any). List all non-identifying relationships (if any). List all independent entities (if any). List all dependent entities (if any). Whenever patients are seen for the first time, they complete a patient information form that asks their name, address, phone number, and insurance carrier, all of which are stored in the patient information file. Patients signed up to be seen by doctor must be a member of at least one insurance carrier. Each time a patient visits the doctor, an insurance claim is generated and will later be sent to the carrier for payment. The claim must contain information about the visit, such as date, purpose, and cost. It would be possible for a patient to submit two claims on the same day. The relational notation for the database is: Patient (Patient ID, Name, Address, Phone, Primary Carrier,…
Consider the following relations:Album (albumId: integer, title: string, artistId (FK): integer)Artist (artistId: integer, name: string)Composer (artistId: integer, name: string)Singer (artistId: integer, name: string)Write the following queries in relational algebra.(1) Find all the titles of the albums.(2) Find all the tuples whose albumId is 2.(3) Rename the relation Artist to Art and attributes to artId, title.(4) Find all the tuples that are either an Artist or a Composer.(5) Find the tuples of Artists who are not a Composer.(6) Find the tuples of people who are Composer and a Singer at the same time.(7) Find the titles of albums created by the artist ‘Black Sabbath’.
